Several months ago, I devised a periodized, 10 day lifting plan. Rep ranges are Day1,2: 3 reps, Day3,4: 6 reps, Day5,6: 8 reps, Day7,8: 10 reps, Day9,10: 12 reps not to failure. My only problem is that I forgot what a program like this would be good for, as I didn’t document it well enough. Periodization is theoretically supposed to induce mass gain, am I correct?
