The Strive puck · In development

You lift.
Strive logs.

Put your phone down between sets.

The Strive puck records your reps and sets as you lift. Follow your routine and the recommended weight, and there’s nothing to enter between sets.

Your routine, already loaded.

Reps and sets logged automatically.

Rep speed you can look back on.

One puck for almost every lift.

From your first set to your last

Phone down.
Next set.

A real set, recorded with the Strive app. Machine shoulder press, 140 lb × 12. The number is each rep’s speed.

Your routine already knows what’s next. You shouldn’t have to keep telling your log.

Start your routine in Strive. Your exercises and recommended weights are already there. Follow the plan, and the puck records your reps and saves your sets as you go.

Rest, get ready, and lift again. You can leave your phone alone between sets and come back to a record of the work you put in.

It goes where the work is: on your wrist for dumbbells and cables, stuck magnetically to the bar or machine for barbell and machine lifts, and on a small magnetic plate under your shirt for bodyweight moves. The strap and plate come in the box, so one puck covers almost every lift.

Beyond weight × reps

Five reps on paper.
A different story
under the bar.

You know when the last rep feels slower. Strive gives you the rep speed behind that feeling, so you can see where the set started to slow down.

That detail is recorded while you lift. Look back after training and see how the set went, rep by rep.

Strive also uses that slowdown to suggest the weight for your next set.

What bar speed can tell you

One set. Five reps.

A few things you might ask

Before you
join the list.

What is the Strive puck?

A small strength training sensor that connects to the Strive app and logs your reps and sets as you lift. Follow your routine and the recommended weight, and it has the exercise and weight ready too. You get a workout log with rep speed data, without typing in each set.

Do I have to log anything between sets?

If you’re following your routine and using Strive’s recommended weight, you don’t need to select exercises, enter weights, or log reps between sets. Start the routine and lift. If you switch exercises or use a different weight than recommended, update that in the app so your log matches your workout.

What lifts does it work with?

Almost everything you do in the gym. The puck comes with a wrist strap and a small magnetic plate, and that’s the whole kit. Wear it on your wrist for dumbbells and cables, stick it straight onto the bar or machine for barbell and machine work (it’s magnetic), and for bodyweight moves it sticks to the plate worn under your shirt. There’s nothing else to buy or attach.

When can I get one, and what will it cost?

The puck is in development. Price and a release date haven’t been announced. Join the waitlist and we’ll email you when there’s news.
