Following your different articles on “strenght circuits” I ask myself the question of using giants sets but for a single muscle group.
Example:
Chest :
Bench press (4-6 reps)
Dumbbell bench press (10-12)
Flys (15-20)
rest
x 3 or 4 sets
Would it be possible to use this type of sets for all muscles by following a frequent approach (like half body or push pull) 6x per week or this is too much volume to recover from?
What I mean is that frequency and volume are oppositions. The higher the volume for a muscle is, the less frequency you can have. One giant set like you mentioned provides 90-150 reps per muscle. If you use a push/pull approach it gives you workouts of 300-450 reps.
Compare that to the Built for Battle plan than has 75, it’s not even comparable.
