HOW: Get a kettlebell in a front rack position on the side you want to lunge towards. Start in a standing position with your feet shoulder-width apart holding the weight, then take a large step towards the side you're holding the weight. Allow your hip and knee to bend and assume a lateral lunge position, then push the ground away using your legs to return to starting position. Repeat.
FEEL: This will feel like a full body workout, from your shoulder holding the weight, to your core maintaining ideal trunk position, to your legs working with the lunge.
COMPENSATION: Do not excessively round or arch your back, the side you lunge towards should have 80% of your weight through that leg, focus on good form that comes with a traditional lateral lunge.
