This is an interesting thread. Had to shake my head at some of it. Bro, not trying to knock you, but you really like to hear yourself talk and some of your information is incorrect. Not going to point out everything, but until you go through a true certification and learn nutrition and lifting (not a mentor trainer that in most cases barely know themselves) you should be weary about preaching training routines. You do make some good points all in the same. The main points to remember in your routine is diet and some type of training interval. Just cardio leads to muscle depletion if you do too much and then you are just skinny fat. Its also about calories in vs calories out.. The right calories. You need to understand macronutrients and create a diet plan on that. I could go on, but this isn't a bodybuilding site so for the purpose of snowboarding training, some kind of high intensity weight training (High rep, lighter weight) and interval training with cardio mixed with the right diet will get you far.
