Top 10 ACL Recovery Exercises for Blokes in Sport

Anterior Cruciate Ligament (ACL) injuries represent one of the most demanding setbacks for blokes in sport, often requiring months of dedicated rehab to return to competitive form. While the recovery journey can seem daunting, a strategic approach incorporating specific exercises has proven highly effective in rebuilding strength, stability and confidence. Understanding and implementing the right combination of rehab exercises not only speeds up recovery but also reduces the risk of doing it again. As sportsmen work through this crucial rehab phase, these ten vital exercises serve as fundamental building blocks for a successful return to sport.

Straight Leg Raises

Mastering straight leg raises marks a pivotal early milestone in ACL rehabilitation for male athletes. This foundational exercise, typically introduced in the first few weeks post-surgery, helps maintain quadriceps strength while protecting the healing graft. When performed correctly, straight leg raises target multiple muscle groups while minimising stress on the reconstructed ligament.

The exercise begins with the athlete lying supine on a flat surface, with the unaffected leg bent and foot flat on the ground. Before initiating movement, proper gluteal activation is indispensable to stabilise the pelvis and maintain proper form. The injured leg should be fully extended, with the foot flexed and toes pointed toward the ceiling. Through isometric contraction, the quadriceps muscle is engaged, pressing the back of the knee firmly into the surface.

Athletes should lift the straightened leg approximately 30 centimetres off the ground while maintaining complete leg extension. The movement should be controlled and deliberate, lasting 3-5 seconds in both the lifting and lowering phases. Initially, perform 3 sets of 10 repetitions, gradually increasing as strength improves. Common errors include allowing the leg to rotate externally or failing to maintain full extension throughout the movement.

To progress the exercise, athletes can add ankle weights or resistance bands, but only under proper medical supervision. It's imperative to avoid compensation patterns, such as lifting from the hip or allowing the lower back to arch. Proper form ensures optimum muscle recruitment and prevents unnecessary stress on the healing ACL. For optimal recovery results, incorporate hands-on physiotherapy techniques alongside these exercises to maintain joint mobility and muscle health.

Hamstring Bridge Exercises

Hamstring bridge exercises build upon the foundation established by straight leg raises, advancing ACL rehabilitation to include dynamic posterior chain activation. This exercise targets multiple muscle groups simultaneously, with particular emphasis on hamstring strengthening and glute engagement, both necessary for knee stability during athletic movements.

To perform the basic hamstring bridge, lie supine with knees bent and feet flat on the floor, hip-width apart. Press through the heels, engaging the hamstrings and glutes to lift the hips off the ground until achieving a straight line from shoulders to knees. Hold this position for 3-5 seconds before slowly lowering back down. Begin with 3 sets of 10 repetitions, progressing as strength improves.

Advanced variations include single-leg bridges and sliding hamstring curls using a stability ball. These progressions further challenge hamstring flexibility and strength while maintaining proper form. Athletes should focus on controlled movements and avoid excessive arching of the lower back during execution.

For ideal results, perform hamstring bridge exercises 3-4 times per week, allowing adequate recovery between sessions. Common mistakes include rushing through repetitions and relying too heavily on lower back muscles instead of hamstrings. Athletes should feel a distinct engagement of the posterior thigh muscles throughout the movement.

As with all ACL rehabilitation exercises, progression should be gradual and pain-free. Athletes should consult their physiotherapist before advancing to more challenging variations, ensuring proper form and technique are maintained throughout the recovery process. For optimal rehabilitation outcomes, the head physio's approach focuses on quick symptom relief while addressing underlying biomechanical issues.

Wall Slides

While progressing through ACL rehabilitation, wall slides serve as a crucial exercise for rebuilding quadriceps strength and knee mobility in a controlled environment. This exercise allows athletes to safely train their knee flexion and extension while maintaining proper form and minimising stress on the healing ligament.

To perform wall slides correctly, begin by standing with your back against a wall, feet positioned shoulder-width apart and about 30 centimetres from the wall. Slowly slide down the wall, maintaining contact between your back and the wall surface while bending your knees. Initially, limit the range of motion to 30-45 degrees of knee flexion, gradually progressing to 90 degrees as strength improves.

Advanced variations can incorporate shoulder taps while holding the slide position, which enhances core engagement and builds overall stability. This modification challenges balance and proprioception while maintaining proper knee alignment. Athletes should focus on keeping equal weight distribution between both legs and avoiding knee valgus (inward collapse).

Key points for proper execution include:

• Maintain a neutral spine against the wall

• Keep feet parallel and aligned with knees

• Engage core throughout the movement

• Progress gradually with depth and duration

• Perform 2-3 sets of 10-15 repetitions

Athletes should monitor pain levels and avoid pushing through sharp or intense discomfort. As with all ACL rehabilitation exercises, proper form takes priority over repetitions or depth. Regular consultation with physiotherapists guarantees appropriate progression and technique modification based on individual recovery status. For optimal results, athletes should complement wall slides with evidence-based treatment approaches under professional physiotherapy guidance.

Heel Slides

A patient's initial progression through ACL rehabilitation often begins with heel slides, a fundamental exercise that helps restore knee range of motion and strengthen surrounding muscles. This controlled movement focuses on gradually increasing flexion whilst maintaining proper form and avoiding excessive stress on the reconstructed ligament.

To perform heel slides, the athlete lies supine on a flat surface with both legs extended. The injured leg's heel maintains contact with the surface while slowly sliding toward the buttocks, bending the knee as far as comfortable. The movement should be deliberate and controlled, holding briefly at the end range before returning to the starting position. This exercise can be performed with or without a sliding aid, such as a towel or specialised therapy slide board.

Heel slides complement static stretching techniques and effectively improve hamstring mobility without placing undue stress on the healing ACL graft. As recovery progresses, athletes can incorporate variations, including active assistance with a strap or the opposite leg to achieve greater flexion. Typically, practitioners recommend performing 2-3 sets of 10-15 repetitions, several times daily during the initial rehabilitation phase.

Athletes should monitor pain levels and avoid forcing the movement beyond comfortable limits. If experiencing catching or sharp pain, they should consult their physiotherapist to adjust the technique. Working with sports physiotherapy specialists who have experience treating athletic injuries can ensure proper form and optimal recovery outcomes. As range of motion improves, this exercise establishes a foundation for more advanced movements in later rehabilitation stages, making it pivotal for successful ACL recovery.

Stationary Cycling

Stationary cycling represents one of the most effective low-impact exercises for ACL rehabilitation, typically introduced around weeks 2-4 post-surgery when adequate range of motion has been achieved. This controlled exercise allows athletes to maintain cardiovascular endurance while minimising stress on the healing ligament. The circular motion helps improve knee flexion and extension in a protected environment, reducing the risk of re-injury during the recovery phase.

When beginning bike workouts, athletes should start with minimal resistance and focus on achieving smooth, consistent pedalling motions. The seat height should be adjusted to allow for slight knee bend at the bottom of the pedal stroke, preventing excessive stress on the joint. Initially, sessions should last 10-15 minutes, gradually increasing duration and resistance as strength and comfort improve.

Athletes should monitor their form carefully during stationary cycling, ensuring the knee tracks properly over the foot and avoiding any lateral movement. As rehabilitation progresses, interval training can be incorporated to enhance cardiovascular conditioning and prepare for return to sport. Athletes should maintain a cadence between 60-80 RPM during early recovery, increasing as tolerated under medical supervision.

For optimal recovery results, athletes can complement their cycling routine with exercise rehabilitation techniques under the guidance of experienced physiotherapists at specialised clinics.

Key considerations include:

• Starting with zero resistance

• Maintaining proper seat height and positioning

• Gradually increasing duration before adding resistance

• Monitoring knee alignment and tracking

• Following prescribed heart rate zones

• Avoiding pushing through sharp pain

• Recording progress with respect to time, resistance, and perceived exertion

Proprioception Training

Restoring proprioceptive function stands as an essential component in ACL rehabilitation, enabling athletes to regain their sense of joint position and movement awareness. Following ACL reconstruction, athletes often experience diminished spatial awareness and reduced neuromuscular control, making proprioception training necessary for preventing re-injury and optimising performance outcomes.

The progression of proprioception training typically begins with static balance exercises on stable surfaces, gradually advancing to unstable platforms like wobble boards and BOSU balls. As stability improves, dynamic balance activities are introduced, incorporating controlled movements while maintaining postural control. These may include single-leg stands with arm movements, controlled squats on unstable surfaces, and lateral weight shifts.

Advanced proprioception training integrates sport-specific agility drills that challenge both balance and coordination. Athletes perform controlled cutting movements, deceleration exercises, and multi-directional hops while maintaining proper knee alignment. These drills are carefully monitored to guarantee appropriate form and prevent excessive stress on the reconstructed ligament.

Throughout the proprioception training phase, emphasis remains on quality over quantity, with careful attention to proper biomechanics and knee positioning. Athletes should avoid compensation patterns and maintain proper alignment between the hip, knee, and ankle. Regular assessment of progress helps determine readiness for advancement to more challenging exercises, ensuring a safe and effective return to sport-specific movements. Working with multidisciplinary team members ensures comprehensive monitoring and optimal progression through each phase of proprioception training.

Walking Lunges

Mastering walking lunges represents a crucial milestone in ACL rehabilitation, combining strength development with functional movement patterns. This exercise effectively bridges the gap between basic rehabilitation movements and sport-specific activities, whilst simultaneously improving hip mobility and balance control. Athletes recovering from ACL surgery can progressively rebuild lower body strength through this compound movement that mimics natural walking and running mechanics.

To perform walking lunges correctly, athletes should begin with bodyweight only, focusing on proper form and alignment. Start by stepping forward with one leg, lowering the back knee towards the ground while maintaining an upright torso. The front knee should track directly over the ankle, never extending beyond the toes. This controlled movement provides essential quad strengthening while engaging the posterior chain muscles.

As recovery progresses, athletes can incorporate variations to increase difficulty and specificity. Adding dumbbells or resistance bands challenges stability and increases muscle activation. Physiotherapists often recommend performing 2-3 sets of 10-12 lunges per leg, gradually increasing distance and resistance based on individual progress and comfort level.

Key considerations during execution include maintaining proper spine alignment, engaging core muscles, and ensuring equal weight distribution between legs. Athletes should pay particular attention to knee positioning to prevent valgus collapse, a common concern during ACL rehabilitation. When performed correctly, walking lunges help restore confidence in weight-bearing movements while developing the strength and coordination necessary for returning to athletic activities. The exercise physiology experts at Activ Therapy Moorebank provide specialised guidance for proper lunge technique and progression during rehabilitation.

Balance Board Exercises

Balance board exercises serve as fundamental tools in ACL rehabilitation, challenging proprioception and neuromuscular control while promoting dynamic stability. These exercises systematically progress from basic static holds to more complex movements, helping athletes regain confidence in their reconstructed knee while developing essential stabilising mechanisms.

Begin with basic single leg balance exercises on the board, maintaining proper alignment with the knee tracking over the second toe. Start with 30-second holds, focusing on minimal board movement and maintaining a neutral spine position. As stability improves, incorporate arm movements and head turns to increase difficulty while maintaining balance.

Progress to dynamic balance training by performing controlled tilting movements in various directions. Practise anterior-posterior tilts, followed by medial-lateral movements, gradually increasing speed and range of motion as control improves. Advanced athletes can combine these movements in circular patterns or figure-eight motions.

Further challenge the rehabilitation process by introducing sport-specific movements on the balance board. This might include catching and throwing exercises, simulated defensive stances, or controlled jumping movements, depending on the athlete's sport and recovery stage. Always confirm proper form and avoid movements that cause pain or discomfort.

Perform balance board exercises 3-4 times per week, with 2-3 sets of each exercise. Rest periods between sets should last 30-60 seconds, allowing for adequate recovery while maintaining engagement of stabilising muscles. Progress only when demonstrating consistent control and proper form at the current level.

Consider incorporating hands-on physiotherapy sessions alongside balance board training to ensure optimal recovery and prevent compensatory movement patterns.

Resistance Band Knee Extensions

To effectively strengthen the quadriceps muscles after ACL reconstruction, resistance band knee extensions offer a controlled and ideal method of rebuilding strength while minimising stress on the healing ligament. This exercise specifically targets the quadriceps muscle group while providing adjustable elastic band resistance, making it suitable for various stages of rehabilitation. For optimal recovery outcomes, consider combining this exercise with tailored management plans developed by experienced physiotherapists.

Begin by sitting on a sturdy chair with proper posture, keeping your back straight and feet flat on the floor. Secure one end of the resistance band to the chair leg or a fixed point behind you, and loop the other end around your ankle on the affected leg. Starting with your knee bent at approximately 90 degrees, slowly extend your leg until it's almost straight, maintaining control throughout the movement. Hold this position briefly before returning to the starting position in a controlled manner.

For best quad strengthening results, perform 3 sets of 12-15 repetitions, gradually increasing the elastic band resistance as strength improves. Pay careful attention to proper form, avoiding any sudden or jerky movements that could compromise the healing ACL. The resistance band should provide consistent tension throughout the exercise, challenging the muscles without causing pain or discomfort.

Athletes should progress through different resistance levels based on their physio's guidance and their recovery timeline. Starting with lighter resistance bands allows for proper form development while reducing the risk of reinjury. As strength increases, advancing to stronger bands helps continue the progressive strengthening necessary for returning to sporting activities.

Mini Squats

During the early phases of ACL rehabilitation, mini squats serve as a fundamental exercise for rebuilding lower body strength and stability. This controlled squat variation allows athletes to gradually restore knee function while maintaining proper form and reducing the risk of reinjury. Mini squats typically involve bending the knees to approximately 30-45 degrees, rather than the full 90-degree depth of traditional squats.

To perform mini squats effectively, athletes should stand with feet shoulder-width apart, maintaining neutral spine alignment throughout the movement. The exercise can progress from using both legs to a single leg focus as strength improves. This progression is critical for addressing potential muscle imbalances between the injured and healthy legs.

Athletes should perform mini squats in front of a mirror initially to monitor proper form, ensuring knees track over toes without caving inward. A physiotherapist may recommend starting with 2-3 sets of 10-15 repetitions, gradually increasing volume as strength and confidence build. Supporting oneself with fingertips against a wall can help maintain balance during early rehabilitation stages.

Common mistakes to avoid include rushing the movement, allowing the knees to extend beyond the toes, or compensating with hip shift. Athletes should focus on controlled eccentric (lowering) and concentric (rising) phases, maintaining equal weight distribution through both feet. As rehabilitation progresses, mini squats can incorporate resistance bands or light weights, preparing athletes for more challenging squat variations in later recovery phases. For optimal results, consider working with experienced physiotherapists at specialised clinics who can properly guide your ACL recovery journey.
