KNOW WHAT YOUR BODY CAN LIFT.
The first ROM-based training system built for bodybuilders
Your range of motion is the hidden ceiling on your muscle growth. ROMRxBodyBuilding maps 274+ exercises to your exact joint angles and tells you which lifts your body is ready to load, which need modification, and which to skip entirely until your mobility catches up. No guessing. No injuries from ignorance. Just data.
Foundational ROM. Safe entry lifts for every muscle group. Build your base before unlocking heavier loads.
Compound progressions and accessory variety. 205 total lifts available once your ROM clears intermediate thresholds.
Specialty patterns, advanced angles, max-tension variants. Full 274-lift library at your disposal.
~150+ individual ROM data points sourced from peer-reviewed journals including JSCR, BJSM, and IJSPT, and leading biomechanics textbooks. Every threshold is evidence-based, not estimated.
