As a personal trainer and running coach, when I prepare run training programs, strength training is always an integral part. Strength training has many benefits including contributing to increased lean muscle mass, strength of connective tissue, bone density, resting metabolism and cardiovascular health. Strength training can also improve balance, coordination and posture, boost energy levels and improve mood. As runners, strength training, particularly exercises focused on lateral hip stability and rotational core strength, helps us attain and maintain proper running form, which in turn allows us to run longer and faster, and reduces the likelihood of injury.
