You need an AI system to calculate what weights people should be using for the different lifts. Build a system into it that would help calculate the progression of weights

These work outs are pretty much the same and don’t change, this makes it get boring very quickly. I like the program and have physical improved my physique and how I feel but at this point I’m just doing it to completion

Finished week 1! Too early to appreciate physical results. But motivation is high, dedication is seamless. Accomplished and proud. Look forward to week 2. Semper

Full workout with proper rest is some work. Had to sub crunches for planks but still got a nice pump.
