How the workout generator works
The generator first picks a split based on your training days. For each day it fills fixed movement patterns: knee-dominant (squat), hip-dominant (deadlift), horizontal and vertical pushing and pulling, plus isolation work.
For each pattern it picks the best exercise that fits your equipment. Your goal sets the reps and rest: heavy with long rest for strength, 8 to 12 reps for muscle growth. Your experience sets the number of sets.
Progressive overload: the key to results
A program only works if you keep making it a little harder. When you hit the top of your rep range on every set, increase the weight. The Stren app does this for you: on every set you see what you did last time and what weight to use now.
