Take a KB/DB in one hand, and stand with feet about shoulder-width apart. Let the KB sit in the center line of your body as you hinge at the hips, sticking your bum back to create a quarter-squat position (see video).
EXPLODE the weight up by driving your feet into the ground, contracting your quadriceps and driving your hips forward. This will create enough momentum to carry the KB straight up, you’ll only have to use a little shoulder strength to complete the rep.
Switch on your abs and obliques at the top of the rep to put the brakes on.
