I've just started trying the old, tried & true 8 sets of 8 reps.
Right now, I'm still experimenting a bit to find the right weight for everything.
Ideally, I'd like to find the correct weight to use for all of the movements using a 1-minute rest between sets. Once that's accomplished, I then plan to decrease my rest times by 5 seconds each week (I train each body part 1x/wk) until I work down to about 30 sec rests. Then, I will start over with the minute-long rests, but with heavier weights.
I don't know how practical this will be since different muscles adapt and improve at different rates. That's why I'm hoping the small incremental changes in rest times will adequately suit all of them.
I'd tried German Volume Training years ago. I liked the principle of the whole cumulative overload idea, but I found it difficult at times to maintain the proper focus and intensity for all ten sets - particularly after a demanding day at work.
Personally, I find the 8x8 to be more manageable.
Trainees will develop strength on these types of programs, but I believe the primary goal of them is hypertrophy. An added benefit is a touch of cardiovascular work once you get into the sub-45 second rests on the compounds, which certainly will provide a bit of conditioning.
Anyone here have any experience with the above?
