FormLox

Record a set and turn your lift into numbers: bar path, tempo, time under tension, and your true 1RM. Plus an AI coach and a built-in video editor.

FormLox turns your phone into a lifting lab. Record a set and get instant, on-device analysis of how you actually moved the bar — no physical tracker, no guesswork.

Built for serious lifters who want to train by numbers, not by feel.

RECORD & ANALYZE • Film a set and FormLox breaks down every rep • Bar path, depth, and joint angles • Tempo — eccentric vs concentric, rep by rep • Time under tension across the whole set • Estimated 1RM, RPE, and reps in reserve • Auto-detects the lift you're doing

Analysis currently supports Squat, Overhead Press, and Deadlift, with more lifts on the way.

TRACK YOUR PROGRESS • Estimated 1RM trends and personal records • Weekly digest of volume, intensity, and effort • Per-lift charts so you can watch your strength climb

YOUR AI COACH • Chat with Lox for workout, recovery, and diet plans • Macro-based meal plans in seconds • Ask for tweaks and it revises on the spot

BUILT-IN VIDEO EDITOR • Trim, add music, text, filters, and transitions • Or just tell the AI what you want and it edits for you • Share your lifts anywhere

REST TIMER & MORE • Built-in rest timer and stopwatch • A full library of lifts and variations

YOUR VIDEOS STAY PRIVATE All form analysis runs on your device. Your training videos never leave your phone — we can't see them.
