the goal dictates the methodology. from a bodybuilding perspective, I can work a lot of those muscles in isolation - curls, pressdowns, presses, lat pull downs, leg curls, leg raises, calf raises, etc.
from a strength and MA perspective, I don't want isolation, as my muscles work in conjunction with one another. I want things like deads, cleans, snatches, kettlebell work, squats, chins, etc.
if my goa is size, I want a moderate number of reps and sets. for strength only, low sets and low reps with maximal weights. For endurance, high reps and high sets, etc.
If I have a fight coming up, I may want to emphasize explosiveness and power, so I could add plyos.
How many days per week I work which body part is also dictated by what my goals are.
i'm nobody...i'm nobody. i'm a tramp, a bum, a hobo... a boxcar and a jug of wine... but i'm a straight razor if you get to close to me.
