Took the day off from weights and just did some cardio. I decided to run since I had not in a couple of weeks. Started off with a 2 minute walk then for 3 minutes jogged on 6.5 and bumped it up to 8.0 till i reached 22 minutes. For the next 8 minutes I made it up to 10.5 and finished with 3.85 miles in 30 minutes. After that I slowed it down to 3.5 and put it on incline of 14.0 and walked for 10 minutes. Give this treadmill workout a try next time you do your cardio. You don't necessarily have to do the same speeds but really push yourself past a point that you thought you couldn't reach for the last 5 minutes. It should be a sprint or close to by the time you hit 30 minutes!
