A wearable that doesn’t care about your 10K time. That’s the pitch from Fort, a new fitness hardware company founded by former Tesla engineers, which opened pre-orders on March 21.

No screen. No heart rate zones. No VO2 max estimate. Fort tracks one thing: what happens when you pick up heavy objects and put them down. Reps, sets, rest periods, time under tension, rep velocity, form feedback. All passively, from a band on your wrist.

I haven’t worn one yet—nobody outside Fort’s team has, and anyone telling you otherwise is guessing. What I can do is break down what they’re claiming, how it compares to what’s already on the market, and whether the price makes sense for someone who actually trains with barbells.

Quick Verdict

Aspect	Assessment
Concept	Exactly what serious lifters have been asking for
Price	$319 device + $80/year ($289 pre-order)
vs. WHOOP Cost	Cheaper after year one, much cheaper by year three
Availability	Pre-order only. No confirmed ship date.
Risk Level	High. Unproven hardware from a new company.

Pre-order if: You’re a dedicated strength athlete frustrated with cardio-focused wearables and comfortable spending $289 on an unshipped product Wait if: You want actual user reviews before committing, or your training is mixed (cardio + lifting) Skip if: You need a wearable that works today, or your budget doesn’t allow for pre-order gambles

What Fort Claims to Track

The feature list reads like a strength coach’s wish list:

• Rep counting and set detection: automatic, no button presses or app interaction
• Rep velocity: bar speed on each rep, which is one of the better proxies for relative intensity. If your squat speed drops 20% across a set, you’re approaching failure whether you feel it or not.
• Time under tension: total duration of muscle engagement per set and per session
• Rest period tracking: passive monitoring of how long you sit on the bench scrolling between sets (no judgment, but also a little judgment)
• Form feedback: this is the big claim. Fort says the band uses accelerometer and gyroscope data to detect movement asymmetries and flag potential form breakdowns

That last one is where my skepticism kicks in. Wrist-mounted sensors can read bar path and velocity reasonably well for bilateral barbell movements. I’ve seen that work in the WHOOP Passive MSK update, though with real limitations. But “form feedback” from a wrist sensor is a much bigger claim. Detecting that your left elbow is flaring on bench press from accelerometer data on your right wrist? I’ll believe it when I see the data.

The Velocity Tracking Angle

Rep velocity is the most interesting part of Fort’s pitch, and it’s the one that actually matters for intermediate and advanced lifters.

Velocity-based training (VBT) has solid research behind it going back to 2010. The basic idea: the speed at which you move a barbell correlates with how close you are to your true max effort. A squat at 70% of your one-rep max moves faster than a squat at 90%. Each rep’s velocity (measured in meters per second) tells you how fatiguing a set is in real time. When velocity drops below a personal threshold (say, 0.3 m/s on squats), you know you’re approaching muscular failure regardless of how many reps you planned. Track that speed across weeks and you can autoregulate intensity without percentage-based programming or RPE guesswork.

Tools like the PUSH Band and GymAware validated this concept years ago. Fort is trying to bring that same measurement to a $319 wrist-worn device.

The problem until now: dedicated VBT tools (linear position transducers, camera-based systems) cost $300-$500 and only work for barbell movements in a gym setting. PUSH Band was the closest to a consumer solution, but it had accuracy issues and the company’s support has been spotty.

Fort is claiming comparable accuracy from a wrist-worn device at $319. If the accelerometer data is clean enough to give reliable velocity readings within, say, 5-10% of a linear position transducer, that’s a real product. If the readings are noisy and inconsistent, which is what happened when WHOOP tried to score musculoskeletal strain from wrist motion, it’s a $319 rep counter with fancy marketing.

The Cost Breakdown: Fort vs. WHOOP vs. Everything Else

Fort’s numbers look good. On paper.

Device	Year 1	Year 2	Year 3	3-Year Total
Fort (pre-order)	$369 ($289 + $80)	$80	$80	$529
Fort (retail)	$399 ($319 + $80)	$80	$80	$559
WHOOP 5.0	$240	$240	$240	$720
WHOOP MG	$360	$360	$360	$1,080
Garmin CIRQA	~$200 (est.)	$0	$0	~$200

Fort’s $80/year subscription covers cloud storage, algorithmic updates, and the app’s coaching features. That’s a third of what WHOOP charges. Over three years, a Fort pre-order buyer saves $191 compared to WHOOP 5.0 and $551 compared to WHOOP MG.

But there’s a catch in the comparison that Fort’s marketing conveniently skips. WHOOP tracks recovery, sleep, HRV, respiratory rate, and cardiovascular strain. Fort tracks strength training metrics. They’re not really competing for the same slot on your wrist—unless you only care about what happens during your lifting sessions and have zero interest in recovery data.

For lifters who already own a recovery tracker and want dedicated strength analytics on top of it, Fort fills a gap. For people looking for a single wearable to replace WHOOP entirely, the feature set doesn’t overlap enough. You’d need both.

We’ve covered every major WHOOP alternative if you’re specifically trying to escape WHOOP’s subscription. Fort isn’t on that list because it solves a different problem.

The Ex-Tesla Thing

Every hardware startup in 2026 leads with their founders’ pedigree. Fort’s team includes former Tesla engineers who worked on sensor integration and embedded systems for the Model 3 and Model Y production lines.

That’s legitimately relevant for a wearable. Building reliable consumer hardware with tight sensor calibration, long battery life, and consistent manufacturing quality—that’s closer to automotive sensor work than it is to software. It doesn’t guarantee the product will work, but the team isn’t coming from nowhere.

What concerns me more than the engineering talent is the fitness domain knowledge. Building accurate sensors is one thing. Understanding how a Romanian deadlift differs from a conventional deadlift in terms of wrist motion signatures, knowing that sumo stance changes the accelerometer profile versus conventional, recognizing that a barbell row and a Pendlay row look different from the wrist up—that’s training-specific expertise that takes years to develop. Fort’s website doesn’t mention any exercise scientists or strength coaches on staff. That’s a yellow flag.

What Could Go Wrong

Pre-order hype is building. The risks are real.

No ship date. Fort’s site says “shipping Q3 2026.” That’s a window, not a date. Hardware startups miss shipping windows constantly. The Garmin CIRQA preview showed a similar screenless form factor announced months before availability, and Garmin has decades of manufacturing infrastructure. Fort has none.

No independent testing. Every performance claim comes from Fort’s own data. No third-party validation. No beta tester reviews. The velocity accuracy claims, the form feedback, the exercise recognition—all unverified.

Pre-order economics. You’re paying $289 now for a product that doesn’t exist yet. Fort is a startup. If they run out of money before shipping, your $289 is gone. Check their refund policy carefully. (At the time of writing, they offer full refunds before shipping. After shipping begins, standard return policy applies.)

Subscription lock-in. The $80/year subscription isn’t optional for full functionality. Without it, Fort says the band will still count reps and sets, but velocity tracking, form feedback, and historical analytics require the subscription. So the “one-time purchase” framing is partially misleading. You’re buying hardware that needs ongoing software to deliver its core value.

Exercise coverage at launch. Fort lists barbell squat, bench press, deadlift, overhead press, and barbell row as supported movements at launch. Everything else—dumbbells, kettlebells, cables, machines—is “coming in future updates.” If your training isn’t built around the big barbell lifts, the device won’t do much for you on day one.

Who This Is Actually Built For

Be honest with yourself about which category you’re in.

The target user: You squat, bench, and deadlift at least three days a week. You care about progressive overload and track your training numbers. You’ve looked into velocity-based training but didn’t want to spend $400 on a GymAware or attach a linear transducer to every bar. You have a separate recovery wearable (or don’t care about recovery metrics). You’re comfortable being an early adopter.

Not the target user: You do mixed training, some lifting, some running, some classes. You want a single device. You need it to work today, not Q3. If you’re after a WHOOP alternative that tracks recovery, Fort isn’t that. Beginners especially: a good strength training app will do more for you than a velocity tracker right now.

How I’ll Test It

I’ve placed a pre-order. When (if) it ships, here’s the plan:

Run it alongside a PUSH Band and my gym’s GymAware unit for velocity accuracy on squat, bench, and deadlift. Compare rep counts against video review. Test the form feedback claims by intentionally introducing known technique errors and seeing if the band catches them. Track battery life over full training weeks.

I’ll update this review with hands-on data once the device arrives. Until then, everything above is based on Fort’s published specs and my experience testing similar claims from other wearables.

The Bottom Line

Fort is building exactly what a lot of serious lifters have wanted: a wearable that speaks their language. Not heart rate zones. Not steps. Not recovery scores. Bar speed, time under tension, rep quality. If the velocity tracking is accurate and the form feedback works even partially, this solves a problem nothing else has solved cheaply.

But right now it’s a promise, not a product.

The $289 pre-order is a bet on a first-generation device from a company with zero track record in fitness hardware. The engineering team has the chops to build good sensors. Whether they understand strength training well enough to make those sensors useful is the open question.

If you’re the type of lifter who already tracks every set in a spreadsheet and has been waiting for a VBT tool that doesn’t require clipping a transducer to the bar—Fort is worth watching. Pre-ordering is a personal call based on your risk tolerance and how badly you want to be first.

Me? I pre-ordered. But I’ve also been burned by fitness hardware promises before. I’ll believe the form feedback works when my deadlift tells me it does.
