MuscleLit
See every
muscle work.
A real 3D body shows each exercise from any angle and lights up exactly what it trains. The camera counts your reps and checks your form. A plan is built around your goal. And now your sets become videos worth posting.
Built around a body you can turn.
Every feature starts from the same 3D body, so what you learn, train and track always looks like you.
Exercises in 3D
Watch each move from any angle, slow it down, see the common mistake, and switch between skin, muscles and X-ray.
Camera coach
Prop the phone up: the camera counts 92 exercises, scores each rep's form, ends the set and tells you when a rep goes shallow. Say "done" or "skip" and it listens. Nothing it sees leaves your phone.
A plan for you
Your goal, your sport, your equipment and your sore joints shape a weekly plan that builds on the last. Ask the coach to change it in your own words, cut a session to 15 minutes, or take a 28-day challenge.
Mirror and muscle cam
The 3D body copies you live, so you see your own form from the side while you move, and your working muscles glow on your own body.
Progress on your body
Muscle balance shows what you train and what you leave behind. Then and now lights the muscles your tape measure says grew, and your 3D twin changes build as you do.
Your week and year in 3D
A short video of your body with the week's muscles lit, a time-lapse of your whole year, a share card for every workout, and a link that gives a friend your plan.
Film a set. Make it a video.
Tap record while the camera counts you. The set is saved to Studio, and a template turns it into a 9:16 video with the count, the glow and the score already on it. Save it or share it anywhere. Creator Studio is free, every template and effect included.
Record a set
One red button in the camera coach, in a workout or from the Studio tab. Up to a minute, counted as you go.
Six templates
Rep counter, Muscle glow, Form check with joint angles, PR attempt with bullet time round your 3D body, Anatomy mirror, and Ghost rival racing your last set.
Challenge duet
"Beat my 25 push-ups in 45 seconds." The video carries a link; your friend's try runs against your count with a clock, and the result throws it back.
Transformation reel
Your progress photos with your weight, a before and after, then your 3D twin changing from day one to today as the numbers count up.
A real edit
The last rep glides into slow motion, each rep lands with a burst, the frame flashes with every form score, and it all ends on a card with your count.
Yours to post
Every export is an MP4 made on your phone. Save it to your gallery or share it straight to any app. Filming, the templates, the challenge duet and sharing are all free; only the transformation reel is Pro.
What's new.
The latest update, on Android and iPhone together.
Creator Studio, free
Film sets, six templates and the challenge duet, free for everyone. The transformation reel is Pro.
The camera counts 92 exercises
Up from 41: bench presses, rows, pull-ups, dips, triceps work, leg machines, leg raises and more. Timed holds and stretches say so on their page.
Hands-free voice commands
Log a set, skip the rest or move on by talking, with the phone propped up across the room.
Drop sets and supersets
Built into the player: the weight drops and the next set starts, or two exercises alternate with one rest.
Then and now
Measure chest, arms, waist, hips and thighs; the muscles that grew light up and swell on your 3D body.
Your 3D twin
The body in the app takes your build from your weight, height and measurements, and changes as they do.
Machine scanner
Snap any gym machine and see how to use it in 3D, with the exercise it belongs to.
