Balance lifting. Instead of having exercises where you’re sitting down or holding on to something or otherwise stabilized, it’s more effective to do them standing up, or on one leg, or on a Swiss exercise ball. These types of exercises force you to balance yourself while lifting, which brings your core muscles into play. This gives you a stronger overall body and allows you to lift more over time.
Slow. Many people contract their muscles slowly and then release more quickly. But if you lift slowly in both directions, you are maximizing each move. Lift and lower to a 5-second count in each direction.
