My trainer, Jonathan Perry, is a running specialist and had me doing a range of strength and flexibility routines designed to help improve my core and enhance my running experience. After warming up on a foam roller, Perry had me focusing on my posture and leg muscles (above) by holding a medicine ball out in front whilst doing squats with one leg suspended behind in a TRX Suspension system. “The idea here is to recreate the motion of landing,” Perry told me. “It’s important to build strength in the key muscles you use when you run, especially where you land on impact with the ground. This can help improve your stability and reduce the risk of injuries while helping increase the power in your hamstrings and glutes.”
