Get one thing to improve.

Prop up your phone and lift. REFLEX measures every rep from the video, names the one thing to work on, and tells you next time whether it landed.

Measured, not guessed

The camera keeps the score.

Thirty-three body landmarks a frame become reps, depth against the knee line, bar path and rep timing. The coach may explain; it never measures. When the angle will not give a number, REFLEX says so instead of guessing.

Nine lifts, each with its own measurements and its own one thing to improve. Squat, deadlift and bench are coached today; the other six are in the pilot.

Film or pick

Prop the phone. Lift.

A countdown gets you to the bar, or pick a clip you already have. Drag the ends to the first and last rep, confirm what it saw, and the set is measured in under a minute.

Your coach

Notes that read like a coach who watched.

What went well, where to improve, versus last time, and the plan for next session. Numbers in a lifter's words: "elbows about 30 degrees short of straight", never "146.4°". Ask it anything about your sets or your week.

The verdict

Every rep, drawn on your video.

Nineteen reps of bench. Rep 6 stopped short, elbows at 106 degrees; rep 7 locked out at 166. The set gets one line, one thing to improve, and the still that shows it. Scrub rep by rep, hold the bottom, step frame by frame.

One correction per set, from day one
Next session card: 100 lb for 2 reps, focus on the same reps at the new load
Next session, decided: the load, the reps, and the one thing to improve first.

Week after week

Talk to your coach. Watch it add up.

Ask anything about your training

"How is my week going?" "Why do my squats keep getting flagged?" Answers come from your own measured sets, never from a generic article.

See the progress, not just the sets

A trend line and an estimated one-rep max per lift, a calendar of what you trained, the ring for your sessions, a streak that survives a busy week.

Keep one thing open until it is closed

The recurring fault stays the focus across sets and weeks. The Sunday recap says whether it moved, and what next week is for.

A rest bar with the clock and the camera one tap away, from the moment the set is handed in. Two, three or five minutes: tap to pick.

03

Today's workout

Home names the day by what you trained, lists the sets so far, and adds the next one to it.

04

Your baseline

The first set of a lift becomes the baseline. From the second, the notes say what changed, with the stills side by side.

05

Ghost rep

Play your best rep over the one you are watching, so the difference is a shape, not a number.

06

Ask the coach

Questions about the set or the week, answered from the measurements. Rate the notes with a thumb; it learns what you find useful.

Nine lifts measured, three coached in depth today. Bad angle? REFLEX asks you to refilm rather than guess.
