I’ve read quite a few articles on T-Nation and I’m a bit confused whether its best to vary sets/rep within a workout or over the week. Some articles have you doing different sets/reps in the same workout, others keep them the same in a workout but change them on different days. Whats the pros/cons of each method?
e.g. some fullbody workouts are like this:
Chin ups 3x8
Shoulder press 3x12
Leg press 3x20
BB curl 3x10
Whereas others suggest doing 5x5 for every exercise in workout A, 3x10 in workout B and 3x15 in workout C.
I’m just looking for opinions on pros/cons of both.
And using either method how would you periodize it for strength / hypertrophy / power?
