Stand up straight with your back to a wall.
Tie a resistance band just above both knees.
Lean your back and buttocks against the wall and walk your feet forward a pace.
Keep your legs hips width apart and your toes pointing forwards.
There should be enough tension in the band to feel as though your knees want to close together.
Keeping the hips distance alignment through the length of your legs, slide your back and buttocks down the wall.
Aim to reach a horizontal position with your thighs before you straighten back up again.
