This exercise requires a high level of balance and is great for core stability as well as ankles and knees 

Unstable lunge with suspension straps - Women's Health & Fitness

How to

Adjust the strap to calf length

Stand facing away from the anchor and place your back foot in the strap

Keep your body tall and shoulders back with core engaged

Bend your front knee into a lunge without letting the knee go over the toe – push your other foot in the strap backwards as your back knee drops towards the ground in a deep lunge

As you straighten your front knee, bring your back foot forward to help you back into the start position

Complete a set of 15 then change to the other leg

Workout from Head Trainer Nikki Fogden-Moore and Ben Wilson.
