Here's an example, taken from Friday and Saturday exercises...
Just as sore as when i used to do marathon volume, and more enjoyable due to the greater intensity and focus on each set-every set counts, no more marathon workouts that are too much about improving muscle endurance. The bottom line is to increase reps/weight over a period of weeks/months:
Excluding warmups, no wasted sets - each set taken to positive failure, then 1 set set of each exercise taken to negative failure using additional cheat reps when strict reps aren't possible. 1 minute between sets:
Lats:
-3 x 10-12 reps, Hammer Strength pulldown.
-3 x 10 leverage rowing, Flex Leverage rowing machine.
Tris:
-3 x 6-10 bent over cable extensions.
-2 x 20 dip machine.
Bis:
-3 x 6-8 reps, Flex Leverage preacher bench.
-2 x 6-8 reps standing cable curls.
Of course you can add in a couple more sets of something else if desired, you get the idea.
Realize full potential and efficiency:
-Full intensity and concentration on EACH set.
-Must find the BEST most EFFECTIVE exercises that really hit the muscle thru trial and error. What the books says are only guidelines, not always accurate. Some machines are great and better than weights, some are not and sometimes weights are best.
-Slow upwards progression in reps/weight over time.
-Good nutrition to facilitate "good" bodyweight gain.
Each muscle hit twice weekly is probably best. Also try thrice, each for a few months and compare results.
