There are several exercises that can help strengthen the muscles around the knee joint, which can help improve stability and prevent injuries. Here are a few examples knee strengthening exercises:
Stand with your back against a wall and feet shoulder-width apart. Slowly slide down the wall until your knees are at a 90-degree angle. Hold this position for a few seconds, then slowly rise back up. Repeat for several repetitions.
Stand with your feet hip-width apart and your toes pointing forward. Slowly lower your body as if you were sitting back in a chair. Keep your knees behind your toes and your back straight. Rise back up to a standing position.
Stand in front of a step or sturdy elevated surface. Step up onto the surface with one foot, then bring the other foot up to join it. Step back down, leading with the same foot, and repeat for several repetitions before switching sides.
Stand with your feet hip-width apart. Take a step forward with one foot, bending both knees until your back knee almost touches the ground. Push back up to a standing position and repeat on the other side.
Lie face down on a mat with your legs straight. Bend one knee, bringing your heel towards your buttocks, then slowly lower it back down. Repeat on the other side.
Straight Leg Raises
Sit or lie down with your legs straight. Lift one leg up to a 45-degree angle, then slowly lower it back down. Repeat 10-15 times on each leg.
Stand with your feet shoulder-width apart, then rise up onto your toes. Lower yourself back down and repeat for several repetitions.
Sit on a chair or bench with your feet flat on the ground. Lift one foot off the ground and straighten your leg out in front of you. Hold for a few seconds and then lower your foot back down. Repeat on the other side.
Using a leg press machine at the gym, sit with your back against the backrest and your feet on the footplate. Push the footplate away from you, straightening your leg, and then lower it back down. Repeat for 10-15 reps.
Remember to start with a few repetitions of each exercise and gradually increase as your strength improves. If you experience any pain or discomfort, stop the exercise and consult a healthcare professional. Also, seek help from a physical therapist if you have had a knee injury.
