If you’re looking for that extra boost to reach your flat tummy then you have to re-look the weight section at the gym.
Dumbbells aren’t just for bicep curls! Like any other muscle, abs need to be challenged to get stronger. So if regular sit-ups aren’t doing it anymore (or if you have to do more than 20 to feel the burn), throw some weights into the mix – and watch your results multiply.
Hold a dumbbell in your left hand and lie face up with your feet wide. Lift your left arm straight up, palm facing forward, and extend your right arm on the floor out to the side. Keeping your legs and right hand on the floor and your left arm raised, sit up. Lower and repeat. Switch arms after 30 seconds.
