Backs are more important than we imagine. A firm and strong back has more chances to have a flat and toned ab. To have firm stomachs we have to do back and abs exercises that help our posture, flatten our abs and burn the excess fat in the desired areas.
These are some pictures of the stars that show us how their strong backs look like.
This is Naomi Watts who is proud to show off her back in a low cut dress.
Courney Cox was photographed during her holidays wearing a bikini and we have pictures of her in bikini that show her toned back bone by bone.
Colbie Caillat joined the trend wearing a sexy dress too that shows her full back.
