Stand tall with a flat back, your core braced and a short band just above your knees. Put a soft bend in your knee and place your hands on your hips. Your feet should be hip width apart. This is your start position. Drive your knees out forcefully against the band whilst simultaneously taking a step to the side. Pause for a count of one, keeping the tension in your glutes with a wide stance and then take another step to the side. Repeat for the required number of reps (or time).
