Sorry I can't help with modifications for the abs/core work out either but I wanted to say that I've done every work out atleast one time through and love them all!!!
That being said, Kenpo cardio+ threw me for a loop the first time. It's very fast paced and Tony doesn't explain alot of the moves before you do them so I got frustrated quickly. The next time I knew what to expect though and it went much better! I did it for the 3rd time yesterday and it's only getting better!
Interval Cardio+ is just AWESOME! Nuff said.
Total body+ moves quickly and fries you up good. It's lots of fun and has great variety and many original moves. As with the original X it is light on the leg work though so I am including an extra leg work out every week.
Upper+ I just did for the first time today and LOVED it as well. Tough tough stuff! I had to drop my weights down ALOT from what I was able to do with the original X. The moves are again, very original.
Abs/Core+ is tough but fun as well. Also fast paced with lots of new moves. Somehow ARX causes more of a burn in the abdominals A/C is still a great work out. }(
I love the original X and got great results with it. I plan to do it again in the future! I think this new series has alot more of a fun factor to it though. Atleast for me. The work outs are tougher but shorter which I also prefer-easier to fit in a busy schedule.
I am nearing the end of week 1 of the Lean rotation and can't wait to see what kind of results I get after another 12 weeks!
What rotation will you be doing? }(
