Sprints!

I've avoided doing much high-impact cardio since injuring my calf. It's been feeling a lot better lately though so I decided to give sprints a go this morning. I planned to do 5 rounds of 30 second sprint, 90 second walk. I foam rolled and did a dynamic warm-up beforehand, and did the sprints at about 70-80% percent capacity. It was fine for the first three rounds but started to get tired during the last two. I was pretty happy with that. Almost full steam ahead!
