Slide training can provide the same anaerobic energy demands as skiing. The next time you take a run, time it, and check your heart rate. Then, work up to matching those results on your slide board. If you are already able to slide as long as your longest run, it's time to beef up the intensity for anaerobic conditioning. Try sliding lower and faster.
Quick reactions enhance performance in every situation on the hill.
The continuous motion of sliding challenges balance and your ability to react quickly to imbalance. Expert alpine and nordic skiers and snowboarders reap these benefits in gates, steeps, bumps, crud, and powder. Novice winter sports enthusiasts are able to learn sport skills quickly with less muscle burn. Many physical therapists have used similar makeshift boards for knee rehabilitation, too. It's a great low-impact tool for aerobic and anaerobic conditioning, balance, and proprioception.
