01 Capture
Film the set
Record one set from a fixed front or side view. No markers, no sensors — just your phone.
- Front or side angle
- Whole set, every rep
Every rep,
measured.
Computer vision and AI read every rep of your set, then coach you to a stronger topset — anchored to the frames that prove it.

The approach
Video in, coaching out
Every set is measured, not eyeballed. Topset turns a phone video into pose data, reads what the numbers say about your technique, and returns coaching anchored to the frames that prove it.
02 Measure
Read the body
Computer vision estimates body pose on every frame, corrects camera tilt, and normalizes to grip width so the numbers mean the same thing every time.
- Per-frame keypoints
- Joint angles & tempo
03 Coach
Brief the lifter
AI reads the measurement tables as the source of truth and returns concise findings — each one anchored to the frames that demonstrate it.
- Evidence-anchored
- One clear fix at a time
04 Compare Future
Compare across sets
Track each technique check from one session to the next — so you can see whether a fix held and catch regressions before they cost you.
- Session over session
- Trend per check
What gets measured
Technique checks
An example for Bench Press
Each bench-press set is scored against a fixed set of technique checks. Every chart and finding on a set report is organized around these.
Bar control
Descent smoothness and the late sticking region, rep to rep.
Left / right symmetry
Whether one side rides higher than the other through the lift.
Wrist stacking
How well each wrist sits stacked over its elbow.
Tempo
Eccentric and concentric timing, and how it drifts with fatigue.
Touch-point consistency
How tightly the bar returns to the same spot each rep.
Grip width
Measured against shoulder width, flagged as a trade-off.
// What's measurable depends on the camera view — a front view can't see the bar's forward/back path.
