I'M CURRENTLY LIFTING IN THE 3-5 REP RANGE. THE ULTIMATE G0AL IS T0 HIT 3X5 WITH THE WEIGHT BEF0RE M0VING UP IN WEIGHT. ESPECIALLY F0R NATURALS, HIGH REP TRAINING ISN'T AS EFFECTIVE F0R PUTTING 0N MASS.
I warm up with one or two sets in the 10-8 range. The work sets, usually two sets also, are 6-4 range. When I get to the point of doing 6-6 or 8-6 reps, I increase the weight. For quads, specially on the leg press, I do more sets like four or five work sets.
Every so often, I'll drop the weight back some and do higher reps for that day. You can get a great pump out of doing several sets of 20-30 reps on the leg press. When you climb out of the machine you'll feel like you can barely stand up, much less walk.
