That's interesting, I would think carrying on one side at a time would increase core strength better then carrying on both sides.I do them mostly one side at a time. I do about 25% of my body weight and that seems to be enough for now.
Are these exercises considered "good" for backs??This is easily done with empty milk cartons, with handles. You don't need expensive weights. Add water gradually increasing the weight over time.
Any exercise done correctly and carefully that builds muscle is good, unless someone has a unique physical issue that would prevent it.Are these exercises considered "good" for backs??
