RULE 4

PUMP UP THE VOLUME

New Zealand researchers had trained men follow three different squat workouts: 10 sets of 10 reps using 75% 1RM (100 reps total), six sets of four reps using about 90% 1RM (24 reps total), and eight sets of six reps using 45°% 1RM (48 reps total).

The scientists found that testosterone levels increased by about 90% in subjects who did the first workout, but saw very little or no change in those doing the other two routines. They suggested that training volume is key in boosting T since neither the 24-nor the 48-rep workout produced much testosterone.
