Question about burning calories....

depends. resistance training (body or weights) will burn the same indoors or out, give or take a few if its hot out. But generally speaking cardio exercises outdoors beats indoors when it comes to treadmills, ellipticals. etc.... since they diminish the amount of energy needed to propel the body forward. Outdoors, you have to keep the pace and move yourself forward. the only way to get close is to play with inclines and resistance levels on the machine. now aerobic and spin classes offer the same benefits as their outdoor counterparts....either way, in or out, its about getting your heart pumping for 30-60 minutes at least 3 times a week. doesn't matter where, just that you do it! good luck!
