Sure, women love a guy with a chiseled six-pack. But that's not the only body part they check out at the beach.
And while each woman has a different favorite muscle, these are at the top of every female's "what I notice" list.
Take a look, then head to the gym and start sculpting.
1. 6-Pack Abs
You could have biceps the size of bowling balls, but if you've got the beginnings of a gut, any discriminating woman will think twice before considering you boyfriend material. Their fear: A little excess midriff meat now means one fat, sloppy man in 10 years.
2. Powerful Forearms
Women see strong forearms and think you can do everything: Fend off a mugger, build a house, and maintain a dexterous touch long enough to leave them extremely satisfied. So roll up those sleeves, and let 'em have a look.
3. A Nice Butt
Women check out your butt because it's a clue to your worthiness as a physical specimen. If you're in great shape, it carries high. Otherwise, your rear end droops like a sack of old potatoes.
4. A Broad Back
A wide back is essential for a V-shaped torso, and women's attraction to it is ancestral. "When it was important that our mates protect us from woolly mammoths on the plains, we looked for a gene pool that could provide us with protection," says Pega Ren, a sexologist in British Columbia.
5. Sculpted Shoulders
"The shoulder muscles are really the muscles of love and war," says Nancy Etcoff, author of Survival of the Prettiest. They also make the whole look when combined with a broad back. Strong shoulders literally sweep women off their feet.
6. Rock-Hard Calves
"Women want an overall sense of strength and fitness," says Etcoff. "If a man looks as if he can lift something but can't run, it looks disproportionate."
7. A Big Chest
"Women treasure your chest as much as you do theirs," says Emily Dubberley, a sex expert based in the UK. "Touching, kissing, ... a man's chest is undoubtedly a turn-on for most women."
8. Large Biceps
In a poll of Cosmopolitan readers, 1 out of 5 women confessed that nice biceps on a man makes them "absolutely melt."
