Q: how can a man lose extra muscle
i dont like looking bulky

A: There's a 99% chance that you're making a mistake in assuming that extra muscle is responsible for making you bulky. In virtually all cases I've ever seen the unwanted bulk comes from extra fat, not from extra muscle, even though the person may be convinced otherwise. Unless you've done quite a bit of strength and power sports or weightlifting or heavy physical labor, you do not have a whole lot of muscle. However it is very likely that you do have plenty of of fat and it's that fat that's giving you the bulky appearence. Please read http://www.mikesfitness.com/content/get-rid-of-unwanted-muscle-mass and be very very sure that you've found the correct reason for your bulkiness.
