Gym setup controls what the app considers realistic
Gym profile and capability switches tell Get2Lift what your gym actually has. That affects initial exercise selection, substitutions, and future recommendations.
When a program is generated from a gym setup, the program keeps that gym context so later recommendations still match the assumptions it was built with.
Equipment steps protect progression from fake jumps
A machine stack, a pair of dumbbells, and a barbell do not increase in the same way. Real equipment steps tell the app what the next load jump actually looks like.
If the next available jump is too large for the target rep range, Get2Lift may ask you to add reps first instead of forcing a heavier weight too soon.
