The push up is one of the best core training exercises for mountain biking and I really like variations that place different and more difficult demands on the core. In this video I show you a “hard core” push up using an Ultimate Sandbag and one using a stability ball…and then I show you one combining both tools for an extremely difficult push up variation.
