Just read this article in Yahoo (I hardly ever read the sensational articles there) but this one said cardio will make you fat!
Wakeboarding is Not cardio, but the ultimate sport of wakeboarding might be the best form of exercise!
I really cannot see anyone who can run a 6 min mile and runs a couple miles everyday Getting fat, but have looked at these ultra-runners and said they need to be lifting some weights, they almost look sickly!
You cannot dismiss cardio, if you are in a sport you need cardio, but your cardio can diminish very quickly(within a week) where you can go a month without lifting and hardly lose any muscle mass.
I would try to go wakeboarding today but my phone died and I left the charger up on Kelleys Island so I will ride my bike for 40 min(for right now I can afford to lose a little muscle mass)
