Exercises to protect your knee joints

Rub your knees. Sit down and flex or extend your calves. Rub your hands together to warm them up, then place them on your knees, massaging them 30 times each on the left and right sides. It is best when you feel a slight warmth in your knees.

Hug your knees to your chest. Stand upright or lie on your back and relax your whole body. Lift your right leg, bend your knee, then hug your knee with both hands, and use force to bring the knee joint as close to your chest as possible. Pause, release your hands, and return your right leg to its original position. Then lift your left leg and do the same as your right leg, doing each 10 to 15 times.

Twist and rotate your knee. Put your legs together, bend your knees and half squat, support your knees with both hands, and gently rotate your knees. You can first rotate from left to right, and then from right to left, rotate each or alternate 10 to 15 times. Be careful to move slowly and gently, not too fast or too hard.

Bend your knees and squat. Stand with your legs shoulder-width apart, place your hands on your knees, and slowly squat down. When squatting, keep your buttocks as close to your calves as possible, pause for a moment, and then stand up slowly. Do this 5 to 10 times. This can exercise your leg muscles and increase leg strength.
