Crosstraining is a training routine that involves several different types of exercise. This works more muscle groups, improves agility, and makes it easier to participate in a variety of recreational sports. Crosstraining may serve to improve specific aspects of your fitness or performance that can lend a hand to your primary sport. Cross-training doesn’t have to be super-intense, though. At its core, it’s all about pairing workouts that will support each other.
When you run, you’re constantly working your legs and arms, but to become a faster, stronger runner, that’s where cross-training comes in. Cross-training can be high or low intensity exercise and is different than just tacking on more miles.
