Training in two or more sports in order to improve fitness and performance, especially in a main sport.
Cross-training, sometimes referred to as circuit training, refers to combining exercises of other disciplines, different than that of the athlete in training. In reference to running, cross-training is when a runner trains by doing another kind of fitness workout such as cycling, swimming, a fitness class or strength training, to supplement their running. It builds strength and flexibility in muscles that running doesn't utilize. It prevents injury by correcting muscular imbalances. And the variety prevents boredom and burnout.
Benefits of Cross-Training
Alternative forms of exercise have definite benefits: improved your fitness, injury prevention and rehabilitation, quicker recovery, and boredom busters. The trick is to approach cross-training as a runner. Runners have their obvious strengths: power, endurance, tenacity. But within those strengths lies the potential for weakness: quads that overpower our hamstrings, neglected upper bodies, and poor flexibility—qualities that could lead to problems.
