a rule like that doesnt stop kids my age from joining and doing aas so thats irrelevant, but i understand what your trying to say, kids under 18 shouldnt be allowed here or to even think aas but i am quite mature for my age
are you doing 5x5/hiit while on this split? is deadlifts on back day? because deads hit your hams and glutes significantly if you use proper form and only 1 day rest between isnt enough imo
i dont think that it is possible for me to progressively overload and maintain constant reps/sets with weights, as a matter of fact i know from experience, if i work my hams harder than the last time on sat then wont that mean i would need more recovery time not equal?
i am somewhat of a perfectionist when it comes to diet, i measure everything, i eat 4500cals a day 300g protien 500+g carbs 150g fat
