That was the first day the wheels in my head started to spin with thoughts of marrying weight training with running. And now, I can see even more how much energy weight training has brought not only to my running, but to my daily life. For starters, strength training helped me get my testosterone back to normal. It’s also brought a tremendous amount of power to my legs, which I feel noticeably on all my runs, and especially when sprinting and on hills. I also feel like I can recruit my arms to do more work when my legs are tired, allowing me to run faster for longer.
