It wasn't until the last third of the DVD that I had to take additional rest breaks from those allotted in the video. (Okay, it was more like laying there on the ground panting for air.) But, I still continued on as best I could. Totally worth it.
I like that the exercises are simple — not much of a learning curve. The idea is to keep pushing yourself. "Dig deeper" as Shawn T. says. He, by the way, I love. I've never really liked the workout hosts much. (Hubby has P90X and we also have a old version of Zumba.)
Shawn T. is motivating and clear on his instructions. Little reminders like:
Keep your knees soft.
Stretch with your chest, not your head.
Don't sacrifice form for speed.
Think like a power squat, use your body from the bottom up. (Something like that.)
No air of arrogance about him — I like that. He's just really good at what he does and seems like a genuinely caring trainer. Yes, I can tell all this from watching him on the TV. LOL!
