Lunge single-leg with other leg float

The one-legged lunge with the other leg floating is a variation of the traditional lunge where the back leg does not touch the ground during the movement. From standing on one leg, you sink through the knee in a controlled manner while the other leg floats backwards. This requires the stance leg to provide continuous stability.

Due to the lack of support from the second leg, this exercise requires extra balance, control and strength from the supporting leg. This makes the exercise very effective for improving unilateral hip, knee and ankle strength and stability.

When this exercise?

The one-legged lunge with floating leg is used to improve unilateral lower body strength, stability and balance. The exercise is especially suitable for athletes who want to develop their control and stability during single-leg movements.

Within rehabilitation, this exercise can be used when sufficient strength and stability are present to safely perform single-leg loads. Due to the higher balance aspect, the exercise requires good technique and controlled execution. Application, loading and progression should always take place in consultation with a physiotherapist or other qualified professional to ensure the exercise is safe and tailored to the individual's load capacity, complaints and recovery status.
