I have not done any exercising in over three years. And although my weight has kept fairly at the same weight give or take a 5ibs difference. I've had for a while now a mild case of love handles, as in there not severe. What exercises can I do to eliminate love handles ? What sits up are best I can do to keep my stomach trimmed, (as I'm not looking for a wash board stomach) that don't require any equipment that I'd have to purchase ?
