Lean is a science-based workout tracker built around the POF method — the most proven training system for real muscle growth.
LOG WORKOUTS IN SECONDS
Track sets, reps, and weight with minimal taps. Auto-fills your last session so you can focus on lifting, not typing.
POF PROGRESS TRACKING
Each exercise shows a progress bar based on the POF method. See exactly how close you are to your target and when it's time to push harder.
880+ EXERCISES WITH VIDEOS
Full exercise library with instructional videos. Search by muscle group, equipment, or name.
READY-MADE ROUTINES
Browse complete, pre-built routines organized by muscle group. Add an entire workout in one tap. Designed with the POF method built in.
COMPETITIONS — CHALLENGE YOUR FRIENDS
Create a challenge with custom rules: choose the scoring method (number of workouts, total volume, POF score, or sets), set start and end dates, and share an invite link. Friends join in one tap. Live leaderboard with real-time rankings and a top-3 podium. Activity feed shows what your friends are training.
SHARE YOUR PROGRESS
