I've was told the intensity of HHA's is intermediate at best. I have TJ's and consider them intermediate so I passed on HHA's. I use intermediate cardio because I like to vary my cardio but I usually have to add another 20-30 cardio fix on the end.
I really don't like them. I got them cheap off ebay and they are too easy for me. If you want them you can PM me your address, I will send them to you. I used them twice. I don't have the whole set (I don't think)
Thank You all for your answers. It's kind of what I thought. Darn it...I just cannot wait for more insanity! Thanks for the offer on the Hip Hop abs, I probably would not use them, but your ofer was so sweet.:
