I am pretty regimented with my sprinting. Once a week I sprint at the track and warm up with a slow 1 mile jog then I do 4 x 400's, 4 x 200's and if I have anything left I will do many 2 x 100's. Also once a week I will do an interval run which incorporates hill sprints, it is a 3 mile interval run where I do 6-8 sprints during the run.
I have been doing them for a couple years and I feel like I have gotten a lot more explosive for other sports because of them. Especially in basketball. You also get a nice lean/ripped look from doing them a lot.

People say I am on a "crazy" diet. What is so crazy about eating veggies, fruits, seafood and organ meats? Just because I don't eat whole wheat and processed food doesn't make my diet "crazy". Maybe everyone else with a SAD are the "crazy" ones for putting that junk in their system.
