Hey JJ, you will be proud of me! I tried the circuit training exercises today and I loved it! I also had looked up circuit training in youtube.com and found some interesting moves.
Thanks so much for this tip. This is something I'll be doing in the new year.

40 min Circuit training
it's not easy!!!!
I did pushups, squat jumps, jump rope, jumping jacks, ski jumps on the step, lateral bound jumps, accelaration wall drill, mountain climbers, and my leg work with ankle weights. WHEW!
