Once you’ve decided what training effect you are after, it’s time to lay out a rep and set scheme. If getting as strong as possible is your thing, you want to keep the reps lower and add more sets. Think 6 sets of 3-5 reps. If getting bigger is your goal, the classic three sets of 8-12 reps will work very well. If you want your training to be more metabolic for the purpose of fat loss, think higher reps like 15-20.
