Multitask by toning your biceps and quads with this exercise. You'll need a set of dumbbells and a resistance band, but if it's too challenging, just use the weights.
- Stand with both feet together, holding the handle of a resistance band in either hand. Step your left foot onto the middle of the band.
- Take a step forward with your right foot, so there's about four feet between your right heel and left toes. Keep your arms by your sides.
- Inhale, and as you exhale simultaneously bend your right knee and both elbows. Your front thigh will be parallel with the floor, and your right knee directly above your ankle. You may need to widen your stance a little on this first lunge, just to make sure you have the correct alignment.
- As you inhale, straighten your front leg and both arms, coming back to the starting position. This counts as one rep. Complete 10 reps on each side.
