DON'T GUESS
THE MACHINE.
GymLens identifies any piece of equipment from one photo — then shows you how to use it, what not to do, and what else trains the same muscles.

Point your camera at any machine, cable, bar, or weight.
Identify
Vision reads the equipment and what it trains, in seconds.
Train
Proper form, common mistakes, and alternatives with real demos.
Knowing the machine is half of it. The other half is the questions — how heavy, how many sets, is my form safe? On every scan, the AI coach reads what you scanned and answers like a trainer standing next to you, with real exercise demos to back it up.
What weight should a beginner start with?
Start with just the bar — 45 lbs. Smooth and controlled for 8–12 reps. If the last rep feels easy, add 5 lbs next session.

We never let AI invent exercise form — it gets anatomy wrong and that gets people hurt. GymLens names real movements and matches them to a public-domain library of 870+ demonstrated exercises, with a video fallback so there's always something to watch.
