What is it to argue about, your coaches are doing what some people may call shitty training. On top of all that volume your trying to do more work on your own which is leading to overuse injuries (shin etc).
I’m sure you are doubting everything your coaches are telling you instead use that time/energy towards workouts and enjoy being a student athlete. Trust me you will have your whole life to train yourself and experiment with CFTS…
Half of the battle is believing!!! As you may know my workouts are a lot different then CFTS but I believe in what I’m doing, only time will tell if it will work. LOL
