play footbag aka hackysack!!...if you get into freestyle footbag or net footbag both are great sources of cardio and will keep you healthy. I blaze everyday, and because i play footbag i stay in great shape and i have entirely lost my gut! It is just overall fantastic and i highly reccomend it to anyone. Because of footbag i have alot of stamina and i can run for a good amt. of time before becoming winded. this is just my advice though, do whatever makes you happy :rasta:
