i'm currently trying a 2 workouts a day, and i want to know if it's usefull to take like 2 times BCAA , pre-workout, post-workout, ... for each workout.
Thank you !
Yes it's useful. Or you could just eat some WHEY protein Isolate after each workout, as the frequency and in turn volume is increasing the BCAAs will help keep you from catabolizing for muscle for energy.
Personally I trained fasted in the mornings, always my better workout, training on a full stomach usually leaves me sluggish and lazy. Personal opinion of course, but i hear a lot of suggestions on eating pre-workout insta-carbs, i just don't think it's all that necessary. As long as at some point before 2nd workout you refill your glycogen in your muscles. You should be fine. Your body doesnt go catabolic in 3 hours, but fill em up, burn em down, fill em up, rest.
