Lunges

How to do it

1. 1

   Stand tall with your feet together and your hands on your hips or by your sides.

2. 2

   Breathe in as you take a big step forward with one foot and lower your back knee toward the floor.

3. 3

   Breathe out as you push off your front foot to step back to the start.

4. 4

   That's one rep — keep your upper body upright throughout, then alternate legs and repeat.

Where you should feel it: The fronts of your thighs and your glutes.
