Hello every one Im cuurntly out of town and am on my second round week 2 of p90x... Is it okay to substitute Plyo with Bike riding im on the second floor of my hotel and with all the jumping im sure it would upset some of the other guest. As far as that goes is it okay to substitue plyo and kempo for other cardio activities as long as you burn the same calories. Thanks!!!
