This is a great exercise to stretch and strengthen your core oblique muscles.
Sit tall in a chair with your feet flat on the floor. Let your arms hang down on both sides of your body.
From here, gently bend to the right from your waist, extending your right hand toward the floor, as far as is comfortable. Return to the starting position. Repeat on the opposite side. That’s 1 rep. Continue alternating for 5 reps total.
Cautionary note: If you have osteoporosis, twisting and bending moves may not be right for you. Talk to your doctor about safe exercise.
