Each exercise has a progression style
Generated exercises are assigned a progression mode. Some are weight-first, where load increases are the first option when performance is strong. Others are reps-first, where you fill out the rep range before adding weight.
The goal is not to force a jump every session. The app tries to move the exercise forward only when the last completed work suggests you are ready.
RIR keeps effort in the right zone
RIR means reps in reserve: how many more reps you think you could have done with good form. If a set target is 8-10 reps at 2 RIR, you are aiming to stop with about two clean reps left.
Get2Lift uses reps, load, and RIR together so it can tell the difference between a set that was easy, appropriately challenging, or too heavy for the current target.
Program phase matters
Beginner-style rolling progression stays simpler and keeps pushing the next week forward. More advanced block progression can include accumulation, deload, and intensification weeks.
That means the app may intentionally lower stress in a deload week, even if the previous week felt strong.
