How it works

Three steps. Then repeat.

01
Set your starting weights
Tell STR where you are now. The program sets a clear baseline for every main lift.
02
Follow the next workout
Show up and do the session on screen. Every set, rep, and weight is ready for you.
03
Finish and progress
Log the workout. STR updates your weights and prepares the right session for next time.

Movement made clear

A video for every exercise.

Watch each movement in the app before you lift, with dedicated male and female video demonstrations, so the exercise you are about to perform is easy to understand.
