Jillian Michaels - can you do 30DS without stopping?

[Hels20]

Posted also In weight loss and then came across this.

I consider myself reasonably fit but I cannot do Level 3 of 30DS without stopping at the first part of cardio. Can anyone do it without stopping? Do I just persevere even if I feel sick? I have been doing her exercises on and off for a year - and do other exercise in between...

I can these days, but I certainly couldn't initially. I still can't do some of her other cardio circuits without stopping though (I find the plank jacks/mountain climbers/plank jacks/mountain climbers one in Ri30 L2 beats me every time).
