I'm a beginning weight trainer that has already seen great gains in just 4 weeks. But I'm wondering what sets/ reps method is best for putting on size ?? I've been doing 3-4 sets of 10-15 reps per set. But I'm reading that if I increase my weight I use and therefore decrease my reps to the 5-8 range per set that I will then notice better gains in size. Advice please !!! Give me some examples of how to stack these sets one after the other for each exercise. Pyramid ??? Did I read about that being a method of doing this ?
