There's nothing better than a good circuit to you wake you up in the morning. Today's ~15 minute workout was tough, but when you're exercising for time, you choose the intensity. Go as hard as you can, but remember that technique is everything so rest if you need to.
You may not be familiar with some of the exercises, so I've included some links. You can also find them using Google. 馃槉
