10 Physiotherapy Exercises for Leg Weakness

A physiotherapist guides a woman lying on a mat as she performs leg-strengthening exercises to rehabilitate weak lower body muscles.

Leg weakness can creep up on you for many reasons, and it can make even routine tasks feel harder than they should. For some people, the right physiotherapy exercises for legs can rebuild lost strength and reduce the risk of falls or further injury. Below, Proactive Health, a physiotherapy and massage therapy clinic in Richmond, BC, shares some helpful exercises the practice recommends.

Strengthen Your Legs With These Physiotherapy Exercises

If you know all about physiotherapy, you may not be surprised to learn that targeted muscle strengthening exercises can treat a range of conditions. These 10 physiotherapy exercises for legs are a good starting point for patients dealing with weakness:

1. Straight Leg Raises

Straight leg raises are an early rehabilitation exercise. They build quadricep strength without putting any stress on the knee joint. 

Lie flat on your back, bend one knee, slowly lift the straight leg to about 45 degrees, hold for two to three seconds, and then lower it.

2. Mini Squats

Mini squats are excellent leg-strengthening exercises. These movements train the quadriceps and glutes.

Stand with your feet shoulder-width apart, hold onto a chair or wall for support, bend your knees 20 to 30 degrees, and then press back up. As your strength improves, your physiotherapist may gradually increase the depth.

3. Calf Raises

Calf weakness affects walking and stair climbing. Strength here is important for balance. 

Stand near a counter or wall, rise onto the balls of your feet as high as you can, lower slowly, and then repeat. Taking three to four seconds on the way down increases the difficulty of the calf raises and builds more strength.

4. Step-Ups

Step-ups directly mimic stair climbing. 

Place one foot on a low, stable step, press through your heel to lift your body, bring your other foot alongside, and then step back down. Lead with your heel to ensure your glutes and quads are doing the work rather than the calf or lower back.

5. Seated Leg Extensions (With a Resistance Band)

You may take your physiotherapy exercises for legs up a notch as you strengthen. For example, once you're ready to add resistance training, your therapist may suggest seated leg extensions. 

Sit in a sturdy chair, loop a band around your ankle, anchor the other end under the chair leg, and slowly straighten your knee against the band's resistance. This is well-suited for people who aren't yet ready for standing exercises, and can be adjusted by using a lighter or heavier band.

6. Lateral Band Walks

Lateral band walks strengthen the hip abductors, which are critical for knee stability and pelvic control. Weakness in the hip abductors is often linked to knee pain, hip issues, and poor balance.

Place a resistance band just above your knees, stand with a slight bend, and take 10 to 15 small steps sideways in each direction. 

7. Heel Slides

Heel slides are a popular range-of-motion exercise after knee surgery.

Lie on your back with straight legs, slowly slide one heel toward your buttocks by bending your knee, hold it briefly, and then slide it back out.

8. Ankle Circles

Ankle stiffness is common after an injury or prolonged rest, and this has a big impact on your lower-body mobility. 

While seated or lying down, lift one foot off the floor, and rotate your ankle slowly in full circles 10 times in each direction.

9. Hip Flexor Stretches

Tight hip flexors pull the pelvis forward and can alter your gait. 

In a kneeling lunge position, place one knee on the floor and the other foot in front, gently press your hips forward until you feel a stretch at the front of the kneeling hip, and hold for 20 to 30 seconds.

10. Single-Leg Stands

The final item on this list of physiotherapy exercises for legs is a single-leg stand. Balance and stability exercises like this can round out your complete leg rehabilitation program. They aim to retrain the nervous system to stabilize your joints.

Stand near a counter for safety, lift one foot slightly off the floor, and balance on the other leg for 20 to 30 seconds before switching. Once that feels manageable, challenge yourself by closing your eyes or standing on a folded towel to create a slightly unstable surface.
