Hey guys,
I just read this threat and I'm amazed by the injuries and that you guys are tough enough to still get back on the water. In my opinion, the right structured training is the key to successful painfree skiing.
You need to look at it as a pyramid. The bottom is big and is about structured strength with a lot of mobility and stability in mind (which trains the small muscles) which we neglect while skiing. A level higher comes the raw strength we all know from the old fashion training style which is build in the off-season (if a waterskier knows what that is...haha!). A level higher comes the quick coordination and balance drills which work hard on the brain/body communication.
Next on top is the absolute power and responsiveness (speed). Since as a waterskier we don't have to run 100m in less then 10 sec we don't need to be so crazy about it, but it's still necessary for our muscles to be quick and react quick on certain circumstances.
Endurance (bike/row/run) are really good for cardio vascular training and burning some calories on the side. But we need to keep in mind that those can make us slow if done too long too much! It's about what your goal is. If your goal is skiing shorter down the line, endurance is only a side gig for training.
Getting to the weight/strength ratio, you of all skiers should know that a 160lbs kid with no strength skis as good as a 6'4" 230 lbs "Tower". It's about how you use your body.
Same in jump for example.
If you guys want to know more about all those things, feel free to message me anytime. I also just launched a new Youtube/Instagram Series for exercise explanation and why/how we do them for waterskiing and why they are crucial for the survival on the water. It's free of course. Check it out!
