I'm changing my morning run

Starting tomorrow morning I plan to change my morning run.  Instead of a steady jog after I do my calisthenics, kettlebells and stretches, I plan to do the first half as a light jog to a park near my house, then some pull ups and push ups at the park, then alternating sprinting and walking to get home.

I keep coming across articles that say high intensity, short burst training boosts production of human growth hormone so I'm going to make that a part of my regular routine.  Anyone who's interested can check out this short article.
