We know the best way to train for a half marathon is to clock as many miles as your body can handle.
But repeatedly engaging in the same movements every week without building supporting muscles can lead to overuse injuries. For this reason, it is important to cross train.
Cross training can include other aerobic activities, such as cycling, swimming, rowing or elliptical. You should also incorporate basic body strengthening exercises such as pushups, leg lifts and exercises designed to strengthen your core, such as sit-ups.
