Back to P90X

It was kind of a rainy dreary early evening after work, and I didn't feel like running in it. So I reconnected the DVD player and did the P90X Kenpo X workout. Felt great. But it's kind of interesting. The people on the DVD wear heart monitors. One person, and I think it's Tony Horton, reports their pulse as being 160. I don't think the Kenpo X workout has ever got my pulse above 120. Surely my conditioning isn't that good...
