Strengthening your knees is crucial for tennis players as the sport involves a lot of lateral movements, quick changes in direction, and repeated stress on the knee joints. By improving knee strength and stability, you can reduce the risk of knee injuries and enhance your performance on the tennis court.

Here are some exercises to help strengthen your knees for tennis…

1. Squats – Squats are excellent for building strength in the quadriceps, hamstrings, and glutes. Stand with your feet shoulder-width apart, bend your knees, and lower your body as if you are sitting back in an imaginary chair. Keep your knees aligned with your toes and your back straight. Return to the starting position and repeat.
2. Lunges – Lunges target the quadriceps, hamstrings, and glutes while also improving balance and stability. Step forward with one foot and bend both knees until your back knee is almost touching the ground. Push back to the starting position and repeat on the other leg.
3. Step-Ups – Find a sturdy step or platform and step onto it with one foot. Push through your heel and lift your body until the front leg is straight. Step back down and repeat on the other leg.
4. Leg Press – If you have access to a leg press machine, it can be an effective way to build quadriceps strength. Sit on the machine with your feet shoulder-width apart, push the platform away from you, and then slowly lower it back down.
5. Hamstring Curls – Use a hamstring curl machine or resistance band to target the hamstrings. Lie face down on the machine or loop the band around your ankle while standing, and curl your leg back toward your buttocks.
6. Calf Raises – Strong calf muscles help support the knees during explosive movements. Stand on a step or raised surface with the balls of your feet, then raise your heels off the ground and lower them back down.
7. Wall Sits – Wall sits are excellent for isometrically strengthening the quadriceps. Lean your back against a wall and slide down until your knees are bent at a 90-degree angle. Hold this position for a set period.
8. Resistance Band Exercises – Use resistance bands to perform lateral leg raises, hip abductions, and other exercises that target the hip and thigh muscles.
9. Core Strengthening – Strong core muscles help stabilize your pelvis and lower body during tennis movements. Incorporate exercises like planks, Russian twists, and bicycle crunches into your routine.

Start any new exercise program gradually and use the proper form to prevent injury. If you have any pre-existing knee issues or concerns, it’s necessary to consult with a healthcare professional or physical therapist before starting a new knee-strengthening routine. They can provide personalized recommendations and ensure that you’re using appropriate exercises for your specific needs and fitness level.
