When I begin lifting, here is a sample of my routine. Let me know what you think.

Chest and Tri

1 easy warm up set for 10 reps
1 slightly heavier set for 6
1 even heavier set for 3
2 heavy sets for 4-6 (want muscle failure in this range?

dumbbell flat bench chest press

1 mod heavy set for 6
2 heavy sets 4-6

dips on machine

2 sets with body weight to failure

lying tri ext

1 warm up 8-10
1 mod heavy 6-8
2 heavy 4-6

standing tri push downs

1 mod 6-8
2 heavy 4-6

This is just day one of the program when I get started. I'm currently waiting to get a weight bench as I cannot afford a membership at the gym. Once I have the bench I will get started and follow the program as close as possible.
