Tomorrow I start F1! I'm quite pumped. Due to enjoying calisthenics and weight training, I believe I could test out a few of the PE's. I will not be doing so for the first cycle (except HBP and RC), because I want to do some extra prehab and mobility before progressing to the harder PE's.
The main reason I want to prehab is because I has a minor shoulder strain at my work 11 days ago at my work. I believe it would be best to easy into F1 rather than start at a very challenging level for myself.
Anyway, on to my question: after a 12 week cycle of doing mainly PE1's, would it be fine to try and test out the later PE's? (PE2 and PE3 for example.) Or would it be best to just progress to PE2 for the extra time spent on Mobility?
