I used several weights for the Medicine Ball workout: 5- and 10-lb. I don't have a 6 lb medicine ball, which really looks ideal for this workout, but I have dumbbells [insert joke here] which serve the purpose. I used the 10 lb dumbbell to start, but I found it a bit too heavy after awhile, and switched to the 5 lb weight, which is a bit too light. It's like the 3 Bears: I need something in-between. I don't really see myself going off to the store to pick up an 8 lb dumbbell, so I'll likely just make do with what I have.
I don't find the Medicine Ball Core Cardio workout too exerting. There are a few moves which I enjoy, but nothing I find particularly challenging. Looking back to the P90X workouts, there are moves which I found impossible at first, then manageable; some are still impossible (airborne pushups, anyone?). This workout just breezes by in comparison. That's why I found it necessary to pair this workout with Cardio Intervals. In essence, doing Medicine Ball Core Cardio is just an extended warm-up for Cardio Intervals.
While I really enjoy Tony hamming it up at the start of the Cardio Intervals DVD, I didn't want my body to become too cool, so I fast-forwarded immediately to the workout. Again, like Medicine Ball Core Cardio, I don't find this workout to be a killer. There are a couple of moves I find challenging. In the half-moon sequence, I find it difficult to raise my free leg parallel to the floor in the time allocated. The jumping side-kicks are difficult for me due to balance issues. I'm just not the greatest kicker around, and although I can certainly Bring It during Kenpo Cardio Plus, I wouldn't say that I'm a strong candidate for Mr. Miyagi's dojo any time soon.
It's a good thing that the entire workout sequence is repeated, because I needed the extra work. By the time the entire workout is over, I had a pleasant, warm feeling. I wasn't exhausted, I wasn't sweating buckets, I wasn't huffing and puffing or grabbing my knees. I just felt that I had enjoyed a reasonable cardio workout which offered a good full body range of motion. It was a good, fairly light cardio combination to end Week 10.
Bring on Week 11!
