This is the correct way to perform a lunge:

Stand with your feet hip width apart, take a large step forwards with one foot keeping your back straight.

Place your hands on your hips for balance.

Then lower your whole body and leave an inch from your back knee to the floor and lift back up. Keep looking forwards and back straight throughout the lunge and tummy pulled right in.

The back foot will be positioned on the toes. Make sure your front knee does not go over your toes.

Repeat 2 or 3 times to obtain the perfect form on each leg.

Use a mirror if possible to check your positioning.

Variations:

• Use free weights to give you more impact, lunge with a dumbbell in each hand to increase the intensity.
• Add an overhead press with a lunge to engage the upper body.
• Lunge while walking forwards and use free weights to have more impact.
