Locker Bag
I do carry a heavy bag or go to my locker more often?
ive just been thinking about those few weeks ... should I wear a heavy bag really the school throughout the day or go to my locker um ... 1,2,3 4 um yep 4 times a day to put my books away and get news on ... as will be more effective for losing weight (low count things hehe), so guess it's strength against cardiovascular lol not 2 you hehe thnx xxn0haxx
I like the way you think. 
Wearing a heavy backpack can help you spend more energy and burn more calories, the more work your muscles a bit. But while walking to your locker once several times a day would also burn calories. Hmmm .... I guess that just mix a week does the bag heavy and walk next week. xoxo
