This exercise is the reverse lunge and its aim is to improve your general leg and trunk strength, along with your balance.

Start the exercise in standing, and take a step backwards to roughly 1 metre behind you, whilst keeping the other foot forward.

The foot that is forward will be the leg which is working during the movement. When your rear foot has touched the floor, from this position lower yourself down by bending the knee of the leg that is forward as low as you are comfortable to do so, aiming if you can that your thigh is parallel to the floor or that your front knee is bent to 90 degrees.

At the bottom of the movement, simply return to the start position by straightening your front leg and take a big step forward with the rear foot to return to the standing position. Aim to keep your chest upright through the movement so that you are looking forward. Remember to keep your front foot flat on the floor with your body weight evenly distributed across the heel and balls of your feet.

Aim to complete the reps and sets as suggested in your rehab programme. You could alternate performing the reps on your left and right side, or decide to them all on one side initially, before swapping over. There are benefits to either method.

If you find this exercise too easy, you could try the walking lunges exercise, which adds momentum into the movement to make it more challenging. Or you could increase the reps you perform or hold some weight when doing the exercise.

If however you found it too difficult, it may be more helpful to try either a step up or single leg sit to stand exercise.
