Should I scale up on the body weight exercises (add weight vest or add reps) if I can somewhat easily complete the prescribed reps at the correct tempo, or do you recommend just sticking to the program as written for now?
Bodyweight exercises like the strict pull up, push ups, or dips, are all considered weight training movements. You are working against your own bodyweight! With that said, in any weight training exercise, as you get stronger you will be able to increase load. This goes for the traditional bodyweight exercise when we prescribe them in the A/B/C portions of your training. Get a weight vest, place a dumbbell between your legs, or hang some weight form your waist with a chain.
