the A1 B1 C1 thing is just a way of organizing a workout. It may mean that the two A's(A1,A2) are a superset together. i would have to see the routine to know.
a FBW using dumbells is a way you can train your whole body using only dumbels(lol).
did you mean to ask me for a sample full body workout using dumbells?lol
the number of cheat meals allowed per weak depends on your own dedication and your own personal cravings. i do not need any cheat meals, so i dont take any.
if you are really craving a cheat meal, 1 a week is the max amount of cheat meals i would allow a week.
remember, diet is a HUGE part(most say over80%) of whether you succeed or not.
that workout book wich told you that was misguiding. i could go into detail about why exhaustion is not neccisary but il just say ITS NOT NECCISARY.
the "detail" part:
training to exhaustion too often will wear down your cetnral nervous system fast, which will cripple your weight training(and your mood, trust me lol)
the goal of a workout is not to exhaust your muscles, but to train your muscles to get stronger and in turn larger by recruiting as many motor units as possible.
this is accomplished by lifting a set weight QUICKLY while maintianing perfect form and control.
When you acquire more force, your body becomes stronger and potentially larger.
The only way to lift a weight fast is to exhert maximal force and recruit many motor units.
to get what you train for, of course you will have to perform enough contractions. training volume still matters.
the reason exhaustion is not neccisary is because there is no increase in motor unit recruitment. il explain.
The more motor units are recruited to the muscles, the more force can be produced.
the more force produced, the faster the weight moves.
we all know that during the last reps, leading to exhaustion are SLOW. which means there is no extra motor unit recrution. it is only fatiguing the muscles.
the key to getting bigger muscles is gaining strength.
the key to getting stronger is neural training of your motor units.
and yes, you should do the exercises i gave you in the workout in that order.
