OK so i'm 15 years old and my goal is as functionally strong and fit as possible mainly just because I want to, I don't really play any sports regularly. I'm 5'9 150lbs and have been doing starting strength for about 1 month now with good gains. My diet is pretty simple I just try and get as much clean quality foods as I can eat day.
As I walk home from the gym there is this hill I walk up and the other day I thought how perfect it would be for doing some sprints. My idea was to alternate doing them 1x - 2x each week on way home from my weight training.
What I'm wondering is since I'm kinda skinny Is doing these sprints going to interfere with my strength gains. Do you think I would be better of just focusing on starting strength and getting a good base up?
