Yes... if you quad is too strong and/or tight, it will literally pull on your knee cap. Here is a diagram of your knee. You can see the quad muscle connects to you knee via all those white thingies which are tendons/connective tissue (illiotibial band)... now you can imagine if you quad was too strong or too tight... it would shorten and pull on your knee (like a clingy girlfriend) causing irritation to your knee (like a clingy girlfriend).

lmao thanks i have conditioning so ive been streching 3 times aday again it really does help...

My daughter when she was 16 had similar issues with the knee/quad thing and now when doing lots of or big drops skiing or riding her knees will be sore. I keep telling her to dial it back because at the rate she is going she'll have to get both knees replaced by 35-40.

Please don't do the leg extension exercise machine. It's one of the worst if not the worst exercise you can do for your knee. The bottom position of it puts a lot of stress on your ligaments + it is not "functional" (hate to use this word) for snowboarding at all. You're better off doing barbell squats (until parallel), deadlifts, romanian deadlifts, 1 legged DB romanian deadlifts, glute ham raise, reverse lunges.

I agree (if you notice my previous page included the 1 legged deadlift and other body weight exercises)... but I don't think doing a few reps in one day just to get an idea of what your quad/hamstring strength ratio is going to do any serious harm.

You don't need to do max weights... just do something where you can do like 12 reps at medium exertion on the leg curl and and find what weight is roughly the same exertion level on the leg extension.... or just do a lot of hamstring exercises and quad AND hamstring stretches. I've never found anyone with overly developed hamstrings (compared to quads) so you really don't need to measure it I guess.
