HOW: Start by standing with a kettlebell in each hand. Bring the kettlebell up into the front rack position. Squeeze your elbows in engaging your shoulder blade muscles. Shift your weight to one side as you bring the other knee to your chest. Alternate marching in place while maintaining the front rack position.
FEEL: You should feel your shoulder blade muscles working and your lower body muscles working.
COMPENSATION: Keep your back upright, don’t slouch. Keep your elbows in. Don’t shrug your shoulders on either side, keep your traps relaxed.
