HOW: Get a kettlebell set up in one hand and pick up your foot off the ground that is on the opposite side of the kettlebell. Keeping your shoulder packed while gripping the kettlebell tight, slowly lower the kettlebell down to the ground just outside your foot by hinging at your hip while keeping your back straight. Return to standing position and repeat
FEEL: You should feel your hamstrings and glutes working very hard to control the lowering phase and initiating the return to standing phase. You should also feel your core working hard to keep your low back in a good position and not arching or rounding.
COMPENSATION: Be sure to keep your back straight by keeping your core tight. Also do not let your pelvis/hips rotate excessively. Think if you were wearing a belt buckle - keep the belt buckle facing forward and not rotating or tilting. Also be sure to focus on keeping your balance and not leaning too much side to side.
