Hi everyone. After listening to Mr. Sommer on podcasts i cant wait to get into j-curls and shoulder extention W dowel. However im at early F1 stages right now, should i wait until those exercises gets introduced in the course or can i "cheat" time and start implementing it from the go? If yes, how often?
btw im doing F1 and all 3 stretch courses since 6 weeks Ago.
