Power of 4

Here is a quick, but very useful tip. I call it "the Power of 4." What I've noticed over the years is that 4 sets is a nexus within the set continuum. If you're wondering what set total works best, then 4 is not necessarily the best choice, but a solid choice. Four sets works well no matter if you're using high reps, low reps or a combination of both.

For example, 4 sets of 8-12 reps is a solid approach for higher reps. But at the same time 4 sets of 4-6 reps provides the minimum amount of repeated effort to hypertrophy the fast-twitch muscle fibers.

All things being equal, however, a varying set total from workout to workout is far superior to a fixed number of sets. But if you suffer from OCD and you need a crutch, then tap into the Power of 4.
