To add more power to your swing, you want to rotate and shift your weight without swaying excessively from side to side. To do this, you need good lateral stability and mobility in your trunk, hips and core.
Set up with your heels slightly wider than your shoulders. On your backswing, shift more of your weight onto your right foot (if you’re right-handed), but don’t let the shift move your hips beyond your right foot. Do you find this easy or difficult? Let’s have a look at your swing and make sure you’re moving effectively.
Having good mobility is important for a more powerful and stable swing, but we also need to make sure you’re getting into the right positions to take full advantage of your mobility.
