The 12 Best Exercises for ACL Injury Prevention

6 Nov 2023
Preventing ACL (Anterior Cruciate Ligament) injuries is essential for amateur and professional athletes who want to stay active and healthy. Here are twelve exercises that can help strengthen the muscles around the knee and improve stability, reducing the risk of ACL injuries:


Squats: Squats are a fundamental exercise that helps strengthen the quadriceps, hamstrings, and glutes. Proper squatting technique is essential to ensure that the knee tracks in line with the toes.

Lunges: Lunges work the muscles around the knee, including the quadriceps, hamstrings, and glutes. They also improve balance and coordination.

Step-Ups: Step-ups involve stepping onto a platform or bench and then stepping down. This exercise helps improve single-leg strength and stability.

Leg Press: Using a leg press machine, you can target the quadriceps, hamstrings, and glutes with added resistance. Be sure to use proper form to prevent injury.

Deadlifts: Deadlifts strengthen the entire posterior chain, including the hamstrings and lower back, which can contribute to overall knee stability.

Calf Raises: Strong calf muscles can help stabilise the knee joint. Perform calf raises using a step or a calf raise machine.

Supine Hamstring Hip Thrusts: Primarily targeting hamstrings and glutes, this exercise provides a stable base for injury prevention, especially concerning the knee joint.

Single-Leg Balance: Balance exercises, such as standing on one leg with your eyes closed, can help improve proprioception, which is essential for injury prevention.

Planks: Core strength is crucial for overall stability. Planks help strengthen the core muscles, which support the pelvis and reduce the strain on the knees.

Weighted Hamstring Curls: Focus on strengthening the hamstring muscles which are vital for knee joint stability. Proper alignment of the knee during this exercise is crucial.

Resistance Band Exercises: Resistance bands can be used for a variety of exercises, including leg lifts and leg abduction/adduction, to target the hip muscles that support the knee.

Box Jumps: When performed correctly, box jumps can help improve explosive strength and coordination, which can be beneficial for sports-specific movements.


Remember that proper form is critical when performing these exercises. If you’re new to strength training or unsure about the correct technique, consider working with a certified personal trainer or physical therapist to ensure you’re performing the exercises safely and effectively. Additionally, including agility and plyometric exercises in your training routine can further enhance your ACL injury prevention efforts.
