Maintaining muscle strength helps support joints, so step up your walk in the park and make it a full-body muscle-strengthening workout. Start with this move.
(A) Sit with feet flat on ground and in line with knees. (B) Keeping your back straight and arms forward, press heels down and stand. (C) With your weight on your heels, slowly bend at hips and knees to sit. Repeat 8 to 12 times.
