Hi guys. This is Max Tapper again, for Howcast. What I'm going to do today is talk about a set. So, what exactly is a set? A set basically is just a certain number of repetitions that you choose to do in any exercise. So, say if I pick up a dumbbell and I want to work my chest and I'm going 10 to 12 repetitions, after 12 repetitions, that is one set. Okay? Now, you can choose different repetitions for different reasons, depending on what you're trying to achieve. Let's say your goal is just complete strength. A lot of times they'll do six sets of repetitions. If your goal is to build muscle, like hypertrophy, then we'll work somewhere between 10 - 12 repetitions, and that's one set. If your goal is for endurance, then you're doing 15-20 reps, and that is still one set. So, a set basically is just a certain amount of repetitions. That's all. All right guys? Get out there. Do your sets and be safe.
