You want to be healthy and injury free so you are looking to incorporate some strength moves into your routine, but you don't want to spend hours and hours in the gym (because you'd rather be running). I know how you feel, so I created this strength training for runners series just for you. I've developed five minute circuits that target the muscles that runners need to strengthen the most. It's a great place to start when you want to be a better, faster, less prone to injury runner! The first in series is my personal favorite, core exercises.
