Yesterday was HIIT in the rain on the school track. Started to feel some stress in tendons around the groin area after a few sprint sessions, so I finished off with four rounds of shadow boxing, and then jogged home with a final sprint up the hill leading to my house. Maybe I'm not used to sprinting at this weight, or something, but I usually don't feel pain like that from mere running.
In terms of diet, I've cut out the weightgainer, along with those crappy frozen pizzas. I plan on eating big still, just cleaner. Today was mostly a rest day. My upper-body is blasted from Saturday's session.
