Cardio workout?

hello. im a thin, 15 yr old boy. i was wondering if this is a good cardio workout...i listen to a rap song on my ipod on the treadmill, and when the song is over, i jump rope for about a minute, and then i do crunches for a minute. then i play the next song and run, and repeat the process like 4-5 times. is this good? also, what is the perfect speed to put the treadmill at while doing cardio? thanks!
Answer:
You didn't say what your goals are.Generally speaking, cardio is not effective on circuits, which is what you are doing.Instead of bouncing around, do 30 minutes on the treadmill or jumping rope, then do your crunches.There is no perfect speed for the treadmill.
this is a good excerise, but your still young, try not to over do yourself
