Hi, guys. This is Max Happer again for Howcast. What I'm going to do today is talk a little bit about circuit training versus interval training. Many people think you accomplish the same goal, but they don't. They're really working on two separate things. Interval training is just varying the intensity on the same exact exercise, whereas circuit is a group of different exercises done in order. That's the difference.
The circuit actually is working on more musculature and having your body balance out that way, whereas interval training is more of a cardiovascular benefit. It's spiking your heart-rate. It's having your body have to challenge itself and deal with a lot of different stresses. Increasing your intensity really high, then bringing it back down for a couple of minutes, then going back up again and bringing it back down. That's what an interval is. The circuit is basically a bunch of different exercises done in a row. There's no real "versus," because you could do both of them to achieve the same goal together.
When you guys ask me out there which one is better, I really can't tell you which one is better, because they do two different things. One is for your cardiovascular system, and the second one is for your muscular system and your cardiovascular system. They're an awesome, awesome way to vary your workout in different ways, and they're awesome to be used together. Get out there. Do both of them. Try both of them. You can do both of them in the same exact workout and have an awesome workout. Again, get out there, try it, and be safe.
