I traditionally have avoided tying my phone to a specific carrier, but I threw all my principles out the window when my local AT&T offered me a free iPhone 17 Pro if I switched, and traded in my beloved unlocked Pixel 9. It was an offer too good to refuse. Now, T-Mobile is offering a similar deal nationwide. Switch allegiances to them and get a free iPhone 17e, no trade-in necessary. Or, you can choose an iPhone 17 if you trade in an eligible device and choose a premium T-Mobile plan. Here are the details.

You have two options: the recently released, affordable iPhone 17e, or the standard iPhone 17 with a more impressive camera.

The iPhone 17e will be totally free with most plans T-Mobile offers (Experience Beyond, Experience More, or the Essentials plan if you're a new member). You can also be a Go5G Plus or Go5G Next member and still qualify. You will need to complete 24 months of bill payments before the phone is truly yours (if you cancel before, you will be charged a pro-rated amount for it). You will still be charged for taxes on the $599.99 iPhone and will need to pay a $35 per line activation fee. And yes, you can keep your old phone number.

For the iPhone 17, the same general rules apply—but you'll also need to trade in an eligible device. These are the phones you can trade in to get up to $830 in credits towards the value of the iPhone 17:

  • Apple iPhone: 13, 13 mini, 13 Pro, 13 Pro Max, 14, 14 Plus, 14 Pro, 14 Pro Max, 15, 15 Plus, 15 Pro, 15 Pro Max, 16, 16 Plus, 16 Pro, 16 Pro Max, 16e

  • Google Pixel: 6, 6 Pro, 7 5G, 7 Pro 5G, 8 5G, 8 Pro 5G, 9 5G, 9 Pro 5G, 9 Pro Fold 5G, 9 Pro XL 5G, Fold 5G

  • Motorola: razr 2025, razr ultra 2025, razr+ 2023, razr+ 2024, razr+ 2025

  • OnePlus: 10 Pro 5G, 9 Pro 5G ​

  • Samsung Galaxy: Note 20 4G, Note 20 5G, Note 20 Ultra 4G, Note 20 Ultra 5G, S20, S20 5G, S20 FE, S20 FE 5G, S20 Ultra, S20+, S20+ 5G, S21, S21 FE, S21 Ultra, S21+, S22, S22 Ultra, S22+, S23, S23 FE, S23 Ultra, S23+, S24, S24 FE, S24 Ultra, S24+, S25, S25 Edge, S25 FE, S25 Ultra, S25+, Z Flip3 5G, Z Flip4 5G, Z Flip5 5G, Z Flip6 5G, Z Flip7 5G, Z Fold3 5G, Z Fold4 5G, Z Fold5 5G, Z Fold6 5G, Z Fold7 5G

Keep in mind, these phones offer up to $830 in credits, which will be applied to your bill over the course of 24 months to pay off the phone. The details will be ironed out by the T-Mobile sales rep you speak with. If you're a new member, you will need to join one of the following plans: Experience Beyond, the Experience More plan with at least 1 line, or the Better Value plan with 3+ lines (starting around $50 per line).

Running influencers are nothing new, but some of us plugged into the online running scene have noticed a shift lately. When I am drawn in by a caption that reads "my 5K race-day routine 🏃‍♀️ (full breakdown below)" only to discover that breakdown is sponsored by a major running app, I have to roll my eyes. Even if they aren't going as far as lying about their times, these "runfluencers" add a lot of noise and distraction to the community.

Not that there's anything wrong with running influencers in theory. I love seeing someone share their journey from couch to 10K—community is everything in this sport! The issue comes when, in their attempts to profit off the content creator economy, brands like Nike Run Club, Runna, and Strava platform a new class of runfluencer: aspirational, relatable, and, often, quite unqualified to be giving training advice. They're even unqualified to handle their own setbacks, as I've watched an influx of content creators blame brands for their injuries (especially the ones falling for crappy AI-generated training plans). If you prioritize being an influencer over being a runner, you can even get banned from the New York City Marathon.

In short, there's a widening gap between people who look like runners giving advice, and the people who actually know how to train runners. And if you're getting your programming advice from the wrong side of that gap, you are leaving valuable wisdom on the table at best, and setting yourself up for injury at worst.

How the runfluencer economy was born

I've watched this running boom happen in real time. The New York City Marathon lottery has become as laughable as the actual lottery. Even local road races are selling out way faster than before the pandemic. A new wave of first-time runners needed guidance, and they're turning to social media.

The problem is that social media rewards specific kinds of running content: race-day vlogs, before-and-after transformations, and even dramatized conflict with other runners. And where professional athletes have off-seasons built into their routines, content creators can't afford to take time off from their content.

These algorithms don't exactly reward nuance, like the unglamorous reality of base-building, or the importance of running most of your miles at a conversational pace. Boring, correct advice loses to exciting, compelling advice every time the algorithm runs its counts.

Meanwhile, brands have incentives to exacerbate the situation. A sponsorship deal with a creator who has a million followers on TikTok will reach more potential customers than a meticulous training guide written by a certified coach who has only 12,000 YouTube subscribers. As on every other corner of the internet, the result is an information ecosystem that's noisier, less reliable, and harder to navigate.

The most common mistakes runfluencers make

I need to get more specific here, because "influencer advice is bad" isn't necessarily true either. Some of it might be just fine—sensible even. But not all of it, by a long shot. Here are the specific red flags I keep seeing from unqualified runfluencers online:

  • Running way too fast, way too often. Roughly 80% of training mileage should be done at easy, conversational pace. Around 20% is fast work, like intervals, tempo, threshold runs. Easy runs don't make for "impressive" content, so the resulting advice pushes recreational runners to run too hard too often, which is one of the fastest routes to overuse injury and burnout.

  • Shoe, gear, and training plan misinformation. Creators are rarely positioned to give unbiased assessments of whether a $200 carbon-plate shoe is appropriate for the beginner marathon runner who is watching their video (it's usually not), because their income depends on the relationship with the brand. This is obvious, but worth saying: Content creators are ultimately trying to sell you something. If they give a ringing endorsement of any sort of app or gear, make sure to do your own due diligence on their claims.

  • Missing the individual picture entirely. A real coach asks questions. What's your injury history? How many days per week can you train? How much sleep are you getting? Influencer advice, structurally, cannot do this. A video or a post is a one-way street, and, again, their advice might even be based on falsified times.

How to evaluate running advice online

So how do you tell the good from the bad? Here's a set of questions to ask before you let someone's training philosophy into your head.

What are their credentials, and are they legit?

Look for trustworthy certifications: USATF (USA Track & Field) Level 1, 2, or 3 coaching certification; RRCA (Road Runners Club of America) certification; an exercise science, or sports physiology degree; or experience as a competitive athlete. A big follower count is not a credential.

Do they explain the why, or just the what?

Giving flat, prescriptive advice—"everyone should run at least five days a week," or "you should always do long runs on Sundays"—without caveats or explanations is a red flag.

To see what the "why" behind a workout might look like, I recommend reading up on why would you have to run slower, why you should start running stairs, and what the hell a fartlek even is.

Do they readily disclose their sponsors or financial relationships?

Sponsorships and brand deals aren't automatically disqualifying, but they should be disclosed clearly and factored into how you weight gear reviews and product recommendations. Undisclosed sponsorships are a significant red flag.

Where to find good (free!) running advice

An enormous amount of excellent running resources exist online, and most of them are totally free. Here are some of my favorites.

  • Hal Higdon's free training plans. These are my go-to. Higdon has been publishing free beginner-through-advanced marathon and half-marathon plans for decades. They're well-structured, conservative in progression, and built on real coaching principles.

  • Runner's World. They have trustworthy, downloadable plan options for whatever you might need, from "Start Running" to "Sub-3-Hour Marathon."

  • Your local running club. There's a solid chance the in-person collective knowledge in a room of people who've been running for years is worth more than most content online.

  • Reddit. Similarly, I often turn to running subreddits (r/AdvancedRunning, r/running), with appropriate skepticism applied. The advanced running community in particular has a high signal-to-noise ratio and actively calls out misinformation. Their wiki is a solid starting resource.

The problem with running apps

Of course, there are everyone's favorite running apps. You won't catch me claiming that Runna, Nike Run Club, and Strava's coach features are outright bad. Runna in particular uses a structured training model, and has credentialed coaches behind the programming.

The issue, then, isn't the apps themselves—it's the influencer-marketing layer that's been placed on top of them, which often creates unrealistic expectations about pace, mileage, and what progress should look like. If you use a structured app, try to understand the training principles it's built on, not just the workouts it assigns.

The bottom line

None of this means you should stop watching running content online—I know I won't. I love seeing other people's journeys, race experiences, and day-to-day running life. There's a big difference, however, between inspirational content and instructional content. Ask yourself the questions above to find runners you can really trust, and tune out the noise.

It happens to the best of us: You write up a comment on an Instagram post, hit send, and, whoops, realize you made a glaring typo. What do you do? Do you delete the comment, retype it, and submit again, doubling the notifications the poster will receive? Leave it, and hope others will overlook your foolish use of "it's" instead of "its"? Neither option is great, but they're the only two choices you have on Instagram, right?

No longer: On Thursday, Instagram announced some exciting news for frequent commenters: Going forward, you'll be able to edit your Instagram comments. Whether you regret one part of your comment, or you only need to fix a mistake, this new feature lets you make adjustments without having to delete your comment entirely, catching up to other platforms that let you make similar edits.

Comment editing, with limits

Comment editing can be a slippery slope. If someone makes a controversial comment but edits it after other people comment en masse, it only creates confusion for users stumbling upon the chaos after the fact. Perhaps that's why Instagram is adding some limitations here. First, you only have 15 minutes after posting a comment to edit it. This is how message editing works on platforms like Apple's Messages app—you only have a finite amount of time to adjust your comments before they're set in stone. Once that 15 minute window is up, your comment is locked to your last edit.

What's more, when you do edit your comments, Instagram places an "Edited" label next to it—letting everyone know you changed the comment in some way. Instagram doesn't make it possible to view the edit history, so no one will be able to see what you said before that last edit—unless, of course, someone took a screenshot of one of your previous comment versions. Also, you can only edit text comments, not images. If you post a comment with an image, you'll need to delete the entire thing to remove that image.

How to edit comments on Instagram

Once you make a comment on an Instagram post, you should now see a new "Edit" button appear next to "Replay" and "Share on Threads." Tap it, and your comment will appear in the text field again. Make your adjustments, then tap the "Send" button again. Remember: You only have 15 minutes from when you first made that comment to make your changes.

Every major browser puts a thin strip of tabs at the top of the window. It's great, until you open dozens of tabs, and all you can really see are little website favicons. A better way exists—placing tabs vertically in a sidebar—but browsers have been resisting it for years. Arc was the first mainstream browser that pioneered a sidebar-based navigation system, and since then it has propagated to Chrome, Edge, Firefox, and Arc's spiritual successor, Zen browser. If you're using one of these browsers, I highly recommend making the switch.

Why vertical tabs make more sense

Most websites are customized for a vertical reading experience, while laptops and desktops have widescreen displays. When you read articles on a website like Lifehacker, there's quite a lot of white space on the left and the right, while that vertical space is actually at a premium. Depending on your display size, your tabs might end up crunched along the top of the display, space that would otherwise be available for viewing the site in question. Moving the tab bar to a sidebar means you've freed up some useful space up top, with the added advantage of being able to see the names of all your tabs—even if you have 30 tabs open at once.

How to enable vertical tabs in Google Chrome

Chrome was the last major browser to add support for vertical tabs, introducing the feature in April 2026. To enable vertical tabs in Chrome, update to the latest version, then go to Settings > Appearance > Tab strip position and switch to Side. All of your tabs will be shifted to a new vertical bar on the left. The URL bar with extensions will move to the top, and a lot of Chrome's interface will disappear.

Chrome also offers a compact mode. You can click the Collapse Tabs icon at the top of the vertical sidebar to only show the website favicons as tabs to save even more space (hovering over a tab will show the tab title). You can still create tab groups from the top of the sidebar, and there's also a handy button to search between the tabs. Pinned tabs show up at the top in their own separate section, too.

How to enable vertical tabs in Firefox

Firefox has a sidebar that lets you add features like an AI chatbot, browser history, and quick access to tabs from other devices. Firefox also lets you move the sidebar to the right-hand side if you wish. To enable vertical tabs here, go to Settings > General > Browser Layout > Vertical Tabs (and make sure that Show sidebar is enabled). When the sidebar is open, click the Customize Sidebar button to customize the shortcuts—including the ability to remove all the Firefox features and AI chatbot shortcuts. There's also a compact mode here that only shows the favicons, but reveals the entire sidebar when you hover on it. Use the Expand sidebar on hover feature to switch to this mode.

How to enable vertical tabs in Edge

To enable vertical tabs in Microsoft Edge, go to Settings > Appearance > Tab Actions > Show vertical tabs. Once set, you'll be able to toggle the sidebar from the toolbar up top. Because Edge is based on Chromium, the vertical sidebar works much like the one in Chrome. Pinned tabs show up top, and you can collapse the sidebar for a compact mode.

Zen Browser has vertical tabs by default

If you are in favor of vertical tabs, you really should consider using the Zen browser. Currently in beta, it's a spiritual successor to Arc (RIP) that is based on Firefox instead of Chromium, with a focus on privacy and speed. But what's particularly relevant for this piece is that Zen Browser uses a sidebar interface by default. Zen uses workspaces to divide up your work, personal life, or projects. Each space can have its own pinned tabs and its own workspace. You can add tabs to the "Essentials" space that stay the same no matter what. There's also a compact mode that hides the entire sidebar unless you hover on the edge of the window. To know more, take a look at our detailed guide on the Zen browser.

I've written before about various software tricks to nudge a smartphone toward dumb-phone territory: stripping the home screen down to essentials, enabling greyscale mode, scheduling downtime windows. I tried all of it, and for a time it worked for me, but only in the way that hiding a bag of chips in a high cabinet works—technically an obstacle, but not really a barrier. One tap to "Ignore Limit," and I'm back to scrolling.

The problem is that the key to unlock everything is right there in your pocket. Turns out I needed a small device called Brick to physically restrain me create a physical barrier, and I can feel my screen time habits finally change for the better.

How Brick works with your smartphone

Brick is a small NFC fob—roughly the size of an AirPods case—paired with an app. You open the app, pick which apps or sites to block (or flip it around: choose only the apps you want to keep, and everything else gets blocked), name it something like Work or Family Time (or just Sanity), and tap your phone to the Brick to activate it.

That's it. And to get everything back, you have to physically walk to wherever you left the Brick and tap again. Each Brick comes with five emergency unbricks you can trigger from the app. I appreciate that those exist, and luckily, I haven't had to use them yet.

Why Brick actually helps you reduce your screen time

Here's the thing I keep coming back to: Every digital-based solution asks you to rely on yourself in the exact moment you're weakest. By the time you're faced with the "Ignore Limit" option, you've already picked up your phone. You're already mid-habit.

Brick changes the physicality of the problem. I've found that the greatest service Brick provides is that it doesn't ask you to resist temptation in the moment; instead, it forces you to set an intention earlier, then it makes that intention stick through physical separation rather than willpower. The research on behavior change says this is exactly the right approach. Environment design beats in-the-moment resolve almost every time. (I just apparently needed a $59 piece of hardware to finally internalize that).

I do have to be honest about how ridiculous this is for me: I spent a lot of money on my phone. And I have now spent additional money ($59) specifically to stop using it. Oh well! That's where my screen time had brought me. On the bright side, Brick is a one-time purchase with no need for a subscription or "premium plan." I'll admit I hesitated to make any purchase, given the irony of the situation and my desire to simply have more willpower. But I've realized my time and attention span is worth the cost, and I'm annoyed it took me this long to act on it.

On Wednesday, Google announced "notebooks," a new feature for Gemini designed to help organize your research materials while using the company's flagship chatbot. Google says you should think of notebooks as "personal knowledge bases shared across Google products, starting in Gemini."

If that's a bit too vague for you, here's a simpler explanation: Notebooks are like Gemini chats, but designed to focus on a single topic, complete with bespoke resources Gemini can reference as you discuss that topic.

How Gemini's "notebooks" work

If you're a frequent Gemini user, you probably have a number of chats spanning any number of topics. The goal of notebooks is similar, but more focused: When you know you want to start compiling resources on a specific subject, you can choose the "New notebook" option on the side panel of the Gemini app, give it a name, then start adding sources. These can be from anywhere, including your Google Drive, your computer, websites, or text from your clipboard. You can also move previous chats into this notebook, if they're relevant to the topic at hand.

Once everything is in the notebook, you can start prompting Gemini and asking the AI questions about your topic. Gemini will then pull from all the resources in the notebook to offer detailed, relevant responses. Depending on your subscription plan, Google says you may be able to add more sources to notebooks, too.

This tool isn't made in isolation. Despite launching in the Gemini app, notebooks will sync with NotebookLM, Google's deep research tool—which is perhaps its biggest perk. That means, notebooks you create in Gemini automatically appear in NotebookLM, so you can not only pick up where you left off, you can take advantage of NotebookLM's features. That means if you create a notebook in Gemini, you can open it in NotebookLM and turn your project into a video, or generate a "podcast" from your Gemini conversations.

I think this cross-platform syncing is probably the best use-case for notebooks. You could already share resources with Gemini if you wanted to chat about a specific topic, but now, you have a dedicated function for that purpose, one that automatically moves across Google's AI research platforms.

How to try notebooks in Gemini

Notebooks will be available to all Gemini users, even those on the free tier, but paid subscribers will have first dibs: Google is rolling out the feature to AI Ultra, Pro, and Plus plans this week, and will make the feature available to mobile and free users in the coming weeks.

The StairMaster may be having a moment, but straight-up stair running has been around forever. As a runner myself, I know real-world stair workouts are one of the most effective and accessible training tools out there, no gym membership required. Especially for my fellow city runners without mountains or hills nearby—or really anyone looking to add some variety into their workouts—stair workouts are a great option to try.

What is vertical training?

Vertical training is exactly what it sounds like: deliberately incorporating upward movement into your workout. Unlike "flat" running, every step up forces your body to fight gravity, which changes the muscular demand, the cardiovascular load, and the mechanical stress on your joints. There are plenty of reasons why you'd want to add vertical training of some kind into your routine.

It increases posterior chain strength

Running on flat ground is largely quad-dominant. Climbing stairs, on the other hand, requires serious glute, hamstring, and calf activation. Over time, stair training builds the posterior chain strength that flat running simply doesn't, and that strength translates directly into faster, more powerful running on any surface.

It gives you stride power and explosiveness

Each step up is essentially a single-leg press against gravity. That builds the kind of explosive hip extension that makes you a stronger pusher-off at ground contact. Sprinters have used stadium stairs for decades for exactly this reason. You don't need to be a sprinter to benefit from it.

It's lower impact than you'd think

Compared to pounding the pavement, the uphill phase of stair running is surprisingly low-impact. The key is going easy on the downhill.

It increases your mental toughness

There's a reason the stairs are the end of the "Rocky" training montage. Training yourself to stay composed and keep your form when your legs are screaming is a skill that pays off in all areas of your life.

These are my favorite stair workouts

Before diving into specific workouts, there are some form cues to understand. You want to make sure you're driving your movement through your whole foot, not just your toes. Try to lean slightly forward from the hips, pump your arms, and keep your gaze a few steps ahead. Avoid letting your heels hang off the edges of steps, locking your knees at the tops of steps, or otherwise causing yourself to trip up or down the stairs.

With all that in mind, here are the stair workouts I like to do when I'm training for a race. Ideally, you'll warm up for at least five minutes before you start climbing.

This simple beginner stair workout

Simply climb continuously for 20–30 minutes at a conversational pace. If you are on real stairs instead of a machine, allow yourself to descend slowly each time. Focus on consistent effort, not speed. Cool down with five minutes of walking and calf stretching.

A posterior chain focused stair workout

After your warm-up, run up one flight hard, and then walk down slow. Run two flights hard, walk down. Build up to five or six flights, then work back down. Rest 60–90 seconds at the bottom between sets.

I know that what constitutes a "flight" changes depending on what you have in front of you, so use your best judgment. The goal is explosive, powerful steps—two at a time, if you can do it safely. Aim for a total session time of around 30 minutes.

And intervals stair workout

This one you can do on a machine or outdoors. Do 8–12 repeats of hard uphill effort for 20–30 seconds, followed by 90 seconds of easy descent and recovery at the bottom. You should be working at a 9 out of 10 effort on the way up. (For experienced runners, this is the stair equivalent of track 200s: short, sharp, and effective.)

The bottom line

Be like Rocky. Seriously, when I'm training for a race with any significant elevation, stair work is non-negotiable. But even if your goal race is completely flat, the posterior chain strength and raw efficiency of stair intervals will make you a better runner on any terrain.
