If you want to hit the slopes opening day without burning out by lunch, it is time to start working on your endurance! Downhill skiing requires a high degree of eccentric and isometric strength: the ability to lower and hold your weight. Most other sports and activities require primarily concentric strength: the ability to lift and push powerfully.
If you want to build your eccentric endurance, you could try the following. Slowly lower into a squat or tucked position for a count of five, hold for a count of five, stand back up to a count of one. Repeat this as many times as needed to “feel the burn”. You could also hold the squat while performing calf raises, or for the next level replace the stand up with a jump.
If you have any questions for optimal training for the upcoming season consult a Summit physiotherapist or personal trainer.
