Good Circuit to Elevate Heart Rate

OK, so today was supposed to be a "light day" at the gym. So I did 20 minutes of cardio and got really really bored of watching news about the economy and the debate tonight, and for some odd reason the music at the gym today completely sucked ass: Britney Spears, Maroon 5, I mean come on, how am I supposed to run, bike, etc to that. 

I decided I would do a little circuit to get my heart rate up and work on some explosive power at the same time, here's how you do it. It's a super set of two exercises to be done consecutively with 1 minute of active rest (walking around room) between sets: 

Grab a medicine ball (~8-12 lbs). Squeeze it tight to your chest like you are giving it a big hug. Now slowly squat down so that your upper leg is about parallel to the floor and jump as high as you can and bring your knees up in front as if you are trying to touch them to the medicine ball. Repeat for 10-12 reps. 

Immediately move to exercise two, which is a lunge push with rope. Wrap a rope, or suspension trainer around 2 45lb (20Kg) plates. Grab a handle in each hand. Now lunge forward so that your arms are bent at the elbow and back near your lats. Push the ropes out as if you were doing a pushup or bench press. Try to push the weight in an explosive fashion as if you were trying to push the weights past you or punch something in front of you. Repeat lunging with other leg. Go to one end of a room/basketball half court (~4-8 steps per leg), turn around pull the weights to you and go back to the other end of the room. Try to get to the other end as quickly as you can without sacrificing form, without losing your balance, etc. 

Take 45 - 60 seconds active rest. By active rest I mean walk around, dont just stand there. You could up the intensity by jumping rope or hopping, or you could just walk quickly around the gym.

It certainly got my heart rate pumping. It also gave me a pretty good leg and chest workout.
