HOW: Pick up one foot and balance on the leg that is in contact with the ground. Hinge forward through your hips while holding onto a kettlebell. Once the balance is maintained in this position, slowly shift the kettlebell from one hand to the other and repeat in this position. It is ok for your knee to remain slightly bent.
FEEL: You should feel like your balance is being challenged. You will also feel your foot muscles, hamstrings, and low back being challenged here.
COMPENSATION: Try not to losing your posture and excessively leaning forward/backward or side to side. If you lose your balance it is ok, take a step and get back to starting position. Do not allow yourself to fall or take the risk of injuring yourself.
