There are no rules. Every person‘s body is different. Just do what the coach says, and stop looking outside. If it works, great. If it doesn’t, go a different direction next time. This isn’t the Olympia, nor is it the last chance she’s ever going to have to compete. This entire thing is an ongoing experiment that only ends when you either stop competing or stop breathing. I’ve been competing for 30 years and no two preps have been even remotely similar.
if I come across sounding irritated, it’s because there’s nothing more maddening than someone that trusts a coach for 11 to 15 weeks and then questions everything they do the five or six days before competition.
