My new thinking is I will try Babbis Light Beginner Routine (can't start much slower than that), feel like maybe I was stretching and jelqing too intensely so gonna go very slow and gentle, and starting with 75 reps (each hand), build up to his 150 see what response I get.

Is it common for beginners to struggle to find this "sweet spot" of intensity to get good PI's and growth?
