Pyramind or three sets

When power lifting I prefer the pyramid workout - reps - 7, 5, 3, 2, as many, burn set. This is good for athletes who have trained this way before and are familiar with it. I have found an easier yet effective way is to start 3 x 8 and after three weeks or so depending on progress go to a 3 x 5 schedule. There is no changing of weight but you can increase your weight once you hit the 3 x 5.
