Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Your plan just got a lot smarter.
Every session now trains what its name says. Back & Biceps
includes real biceps work, leg day mixes squats with hinges
and lunges instead of stacking squats, and exercises stay in
the workout they belong to.
byOne also asks how much lifting you've done. New to it? Your
first plan starts on machines and guided movements instead of
straight onto a barbell — and picks a number of days you can
actually recover from.
New in Analysis: a muscle map showing where your training
landed over any period, and which areas you've been skipping.
If byOne has been useful, you can now leave a tip in Settings.
It stays free either way.
