Stand with your weight on both legs, feet together, hands on hips.

Keep your head and chest up and out and your back straight.

Shift your weight to your left foot and take a large step sideways with your right foot, toes pointing slightly outward.

As your right foot comes in contact with the floor, shift your weight onto it, bending your right leg. Try to keep your shin vertical and get your thigh close to parallel to the floor.

Keep your left leg straight, toes pointing forward, torso centred.

Return to the starting position by pushing against the floor with your right foot.

Repeat, then do the lunges with the left leg.

- Don't let your body bend forward or towards the lunge side.

- Don't make the lunge bigger than you can handle i.e. you should be able to return to the central position without losing your balance.

- Don’t let your bent knee go forward further than your toes or rotate inwards: this can stress the knee joint.

- Keep your abs contracted and your spine straight.
