I've read articles on the release of gh during sprinting and how it could help with gains. What would be a good way to incorporate this into my routine? After I do a leg day, i'm usually sore for 3 days. So I don't think it would be plausible to sprint on those days without risking injury. I would like to manipulate the hormones released in sprinting to help my routine. If this could even be be possible... I realize this is far-fetched, but I am willing to try it to see its benefits. I was thinking of something along the line of all out sprints for 30 seconds, followed by 2-3 minutes rest, and then repeating that 4-5 times. And possibly do that in the mornings 3 days a week.
