If you want to get bigger you still do not need to train to failure, says Pavel, but you must increase your total tonnage lifted, or volume. Thus, an example of a strength workout for Pavel would be a few sets of doubles with 90% of your 1RM, while if you were training for size you might want to do 8-10 sets of 4-5 reps with 80% of your 1RM. All of these sets are terminated one rep short of failure, just like in a strength workout. Pavel feels that when someone tells you about how they did a set of 27 reps to total and utter failure on the leg press machine and puked 3 times and couldn't walk right for 3 days, this is nothing more than histrionics.
