The first couple times I did parts of Kimberly's new one, my HR wasn't that high....but doing it the other day, I really concentrated on getting low in my legs during moves and actually got my HR up pretty good....for a kickbox workout. I bought Powerstrike 3 once and sent it back. It did not get my HR up at all. Everyone says that 1&2 are the good ones but you can't get those any more...so I never tried them.
Other than Cathe kickbox, the only other KB workout that gets my HR up pretty high is CIA's last year's Criss Cross Cardio with Sherri Jacquelyn. It's an interval kickbox workout with a couple high/lo moves thrown in for HR and jumps. It also has a Capoiera leg segment. You can probably get it now at cheaper places since it's been out. The music was half decent on the CIAs last year, but this year, they've really outdone themselves! I should email Greg and let him know how much I appreciate it so they keep doing it! I probably shouldn't say this here, but I actually like it better than some of Cathe's recent stuff .....her last series didn't click with me music wise. I loved the Hardcore's music though...........and I hate Buttercup and Girls Just Wanna Have Fun for a general reference of my musical tastes.
Now that I've severely Hijacked this thread...........I'll go now!! LOL.
