Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

• Build your own plans with sets, reps, rest and RPE - prescribed when you start • After a workout, update your plan's targets with what you actually lifted • Plan rest times now show on every set, and reps no longer cut off at 2 digits • Plans you've already started now show as in progress on the home screen
