A small box on the floor, a thin cable clipped to the bar, a phone propped on the rack, and after every rep of a heavy squat a number pops up: 0.31 m/s. Last week the same weight moved at 0.27. Nobody has to guess whether you’re stronger; the bar told you. That’s velocity-based training, and it’s the most useful wearable tech for powerlifters. The classic fitness watch is less helpful under a barbell: it can’t see bar speed, it struggles to count squats and deadlifts, and heart rate says little about a heavy single. This page sorts out what’s worth buying for powerlifters, from a garage-gym beginner to a coach running a college club: velocity devices, heart-rate sensors and the recovery trackers that watch your sleep between sessions.

Prices change often. The prices below are what we saw at the maker or a major retailer in October 2026; check the current price before you buy. Back to the powerlifting hub.

What powerlifters actually need to track

• Bar speed: the core of velocity-based training (VBT). As a weight gets heavier relative to your max, it moves slower, so speed is a daily readout of readiness and a way to set loads. A 2021 meta-analysis found VBT built squat strength about as well as classic percentage-based programs. It’s a different way to steer training, not a shortcut. How it fits a program is on our powerlifting training page.
• Sleep and recovery trends: how much you slept, resting heart rate and heart rate variability (HRV) over weeks, especially during a hard block or a slow diet toward a weight class. See HRV for athletes.
• Heart rate during conditioning: useful for cardio days and rest timing, not for judging a heavy set.
• A training log: sets, reps, loads and RPE. A notebook or a spreadsheet still works fine.

The best wearables for powerlifters

1. RepOne Tether: best for measuring bar speed

A linear position transducer (LPT) sits on the floor and attaches to the bar with a thin cable, measuring how far and how fast the bar moves. A 2021 systematic review of commercial training devices concluded that linear transducers were more accurate and reliable than other device types, though it also noted that many validation studies didn’t use a gold-standard comparison. That suits the squat, bench and deadlift, where the bar moves in a fairly straight line. RepOne started as an open-source project called OpenBarbell. The Tether costs $449 at the maker and comes with straps and a USB cord. The personal app is free; team software costs extra.

• Good: the most accurate device type for barbell lifts; free personal app.
• Watch out: a cable to set up each session; pricier than sensors that sit on the bar.
• Best for: powerlifters running VBT seriously, and coaches.

2. Vitruve: an LPT that fits heavy, slow lifts

Vitruve is another linear transducer, listed at €447 by the maker. A 2024 validation study found it reliable at slower bar speeds (below about 0.45 m/s on the bench and 0.75 m/s on the squat, using mean velocity), but less accurate at faster speeds. That’s a good match for powerlifting, where the work that matters most is heavy and slow, and less so for fast, light speed work. Phone-camera apps are the budget route; Vitruve’s own guide notes there’s little research validating camera-based systems.

3. Enode Sensor: best compact VBT sensor

The Enode is a 16-gram inertial sensor (accelerometer and gyroscope) that straps to the bar, a weight-stack machine or, with a belt accessory, your hips for jumps. It shows live velocity, power and force in the Enode app. The maker lists about 12 hours of active use, micro-USB charging, and data sent to the phone at roughly 65 Hz. It’s €329 at the maker and $329 at SimpliFaster in the US.

• Good: tiny, no cable, quick to move between bars and exercises.
• Watch out: inertial sensors were generally less accurate than linear transducers in the 2021 review; compare like with like (same sensor, same setup).
• Best for: lifters who want easy daily speed tracking in a busy gym.

4. Polar H10: best heart-rate strap

Chest straps measure the heart’s electrical signal and track an ECG closely; wrist sensors are less accurate, and worse at high intensity. The Polar H10 ($104.95 at Polar) runs up to 400 hours on a coin battery, pairs over Bluetooth and ANT+ with most watches and apps, and stores one session on its own. For powerlifters it’s most useful on conditioning days and for seeing how fast heart rate comes down between heavy sets.

• Good: accurate, long battery, works with almost everything.
• Watch out: heart rate doesn’t measure how hard a heavy single was.
• Best for: lifters who also do conditioning or cardio.

5. Garmin Forerunner 570: for powerlifters who also run

Garmin’s strength activity records sets and counts reps (the count shows after four reps). You can edit reps and add the weight for each set, and follow strength workouts built in Garmin Connect. Garmin notes reps are counted when the arm wearing the watch returns to the start, so leg exercises may not be counted, and you’ll often fix squat and deadlift sets by hand. The Forerunner 570 ($549.99) adds HRV Status, Training Readiness and up to 11 days of battery. It’s more watch than a pure powerlifter needs, but a good fit if you run or do conditioning too. A 2026 study also found smartwatch calorie estimates were poor during resistance exercise, so treat that number loosely.

6. WHOOP 5.0 and Oura Ring 5: best for recovery tracking

WHOOP is a screenless band sold as a membership (Peak, $239 a year, sensor included). Its Strength Trainer feature estimates “muscular load” from the sets, reps and weights you log, plus motion data, and the maker says it works on WHOOP 4.0 and newer. Oura Ring 5 ($399 plus $5.99 a month) is excellent for sleep and readiness trends, but Oura’s own FAQ advises taking the ring off for high-friction activities like weightlifting. That’s no problem if it’s mostly a sleep tracker. Our WHOOP vs Oura vs Garmin comparison goes deeper, and WHOOP alternatives covers cheaper options.

• Good: long-term sleep, HRV and resting heart-rate trends that help you plan deloads.
• Watch out: ongoing fees; a readiness score is a hint, not an order.
• Best for: lifters who want to connect sleep and stress to training.

How to choose a wearable for powerlifting

• Want to steer training by bar speed? Get a VBT device: an LPT for best accuracy on the squat, bench and deadlift, an IMU for convenience.
• Use the same device and setup every time. Readings vary between brands, so trends on one device matter more than absolute numbers.
• Want recovery data? Pick something you’ll wear to bed: a band, ring or watch.
• Count the subscription. Two years of WHOOP or Oura fees can cost more than a VBT sensor.
• Meet day: leave the tech in the bag on the platform and follow your federation’s rules on what you can wear. Meet-legal gear is on our powerlifting gear page.

Wearables for powerlifting: FAQs

Is velocity-based training better than percentages?

Not clearly better, but just as good. A 2021 meta-analysis found no significant differences between VBT and percentage-based training for squat strength, jumps, sprints or change of direction. Many lifters like VBT because it adjusts to how they feel that day.

What is the most accurate VBT device?

A 2021 systematic review found linear position transducers more accurate and reliable than other types, such as bar-mounted inertial sensors. Even within one type, accuracy can vary with bar speed, so check validation studies for the lifts you do.

Can a smartwatch count my squats and deadlifts?

Not reliably. Garmin, for example, counts reps when the arm wearing the watch returns to the start, and notes leg exercises may not be counted. You can log or edit sets by hand.

Should I wear a smart ring while lifting?

Oura advises removing its ring for high-friction activities such as weightlifting, so most lifters take it off for training and wear it for sleep and recovery tracking.

Do I need a heart-rate monitor for powerlifting?

Not for the lifts themselves; heart rate says little about a heavy set. A chest strap is useful if you do conditioning work, and a recovery tracker can show sleep and HRV trends between sessions.
