Every rep. Every posture.
Finally readable.

Most wearables track movement: steps, reps, minutes. The Muscle Puck by LongevityQ reads the muscle signal behind it, synced to video, so you finally know which muscles are doing the work, not just how much you moved.

A small clip-on wearable that reads your muscles in real time and lines the signal up with video of your workout.

You've Been Guessing

You've been training hard. But do you know if the right muscles are firing?

Your form looks right. But you still can't tell if the right muscles are actually working, or if something else is quietly doing the job instead. The Muscle Puck reads the signal, not just the movement.

Watch your muscles work, rep by rep.

The Muscle Puck reads the electrical signal from your muscles in real time and lines it up with video of your set. Scrub back to any rep and see exactly which muscles fired, when, and how hard: the difference between guessing and actually seeing what your body did.

What You'll Finally See

What you'll finally be able to see.

Are you hitting the muscle you meant to?

Think a lift should be working your glutes but it's really all quads? Now you'll see which muscles actually did the work, and adjust until you're training what you meant to.

Is one side carrying the other?

Watch when your stronger side quietly takes over. Catching a left-right imbalance early is how you fix it before it turns into an injury.

Are you fading before you think you are?

See your muscle signal drop as you fatigue: a real read on when a set is actually done, not just when it starts to feel hard.
