Ht. 5'0", Wt. 139 - i read on the internet that doing 10 minutes of jumping jacks burns the same amount of calories as running a mile. is this true? because jumping jacks really do get your heart pumping. the scale finally says i'm below 140! it read 139 this morning. so i guess that means i've lost 8 pounds. all i've been doing is 200 j. jacks a day and lifting weights two times a day, doing 15 reps three times, and drinking water. something i'm doing must be working!
