Since I've been feeling some serious lactic acid buildup in my legs during these workouts, I decided to do some googling on lactic acid and exercise. Sounds like way back, scientists thought that the lactic acid actually diminished performance of athletes. They actually thought that was what caused muscle soreness after a workout. Turns out that lactic acid is actually a fuel source for the muscles and can improve performance!
I'm hoping I can see the results of all this crazy burning in a couple weeks. I signed up for a 10K, and I'm not actually running right now. The Insanity workouts though are high intensity and there is impact, so I think they'll be a great training source. I can't wait to see how I do! For those who haven't read my P90X portion of the blog, I actually ran a half marathon in May during my P90X program, and I didn't train for that. I actually finished faster than one of the races I ran that I trained for. If that's not a testament to the quality of these workouts, I don't know what is!
