This lunge variation will tone up your lower body and arms, but that twist will make your core work, too.
- Begin with your feet together holding a five- or eight-pound dumbbell in each hand.
- As you step back with your right foot for a deep reverse lunge, press up your weights for a bicep curl.
- Using your core strength, rotate your chest towards your left leg and extend your arms out to either side and hold. Step back to the starting position.
- This completes one rep.
