Strengthening exercises that target the muscles surrounding the knee joint are essential for runners looking to prevent injury and reduce knee pain. Strong quadriceps, hamstrings, glutes, and calves provide the support and stability needed to absorb impact, maintain proper alignment, and move efficiently. A balanced strength training routine can significantly enhance knee support and improve your overall running performance.

1. Squats for strength and stability

Squats are one of the most effective exercises for building lower body strength. They primarily target the quadriceps, hamstrings, and glutes—all key players in knee support. When performed with proper form, squats help stabilize the knee joint and reinforce proper biomechanics.

Keep your feet shoulder-width apart, engage your core, and lower yourself by pushing your hips back and bending your knees. Make sure your knees don’t extend past your toes and keep your chest lifted. Try variations like:

  • Goblet squats – great for maintaining form with added weight.
  • Split squats – help build strength in each leg independently.
  • Single-leg squats – excellent for balance and isolating weaker muscles.

2. Lunges for better balance and coordination

Lunges are another powerhouse movement that strengthens the muscles around the knee while improving balance and coordination. Depending on the variation—forward, reverse, or lateral—lunges challenge your stability and engage your core.

To perform a basic lunge, step one foot forward and lower your body until both knees are at 90 degrees. Keep your front knee aligned with your ankle, and avoid letting it extend past your toes. Hold weights for extra resistance, and try these variations:

  • Walking lunges – boost coordination and hip mobility.
    Reverse lunges – place less strain on the knees while still building strength.
  • Side lunges – strengthen the inner and outer thighs for lateral knee support.

3. Leg presses to target the quads and glutes

The leg press machine is a controlled way to strengthen the quadriceps and glutes without overloading the knee joint. Adjust the seat so your knees are at a 90-degree angle when your feet are on the platform. Push through your heels, not your toes, and avoid locking out your knees at the top of the movement.

This machine is especially useful for those recovering from minor injuries or easing into resistance training.

4. Hamstring curls for posterior support

The hamstrings play a crucial role in stabilizing the knee, especially during deceleration and landing. Hamstring curls, whether done on a machine or with resistance bands, help balance strength between the front and back of the thigh. Perform them slowly and with control to avoid relying on momentum.

5. Calf raises to improve ankle and knee stability

Often overlooked, the calves support ankle movement, which in turn affects knee alignment. Strong calves help maintain stability during the push-off phase of running. Do calf raises on flat ground or on a step for a deeper stretch and fuller range of motion. Hold weights to increase resistance.

Incorporating these targeted strength exercises into your weekly routine can greatly reduce knee pain and enhance your performance as a runner. Building strength in the quadriceps, hamstrings, glutes, and calves improves stability, absorbs shock more efficiently, and helps you run longer, faster, and with fewer injuries.
