biceps development.?

Question

i have to develop my biceps without using weights can any one tell me the way.

Answer 1

pushups...or just lift big things. the more you work the muscles, the bigger they will get

Answer 2

You need a pullup bar or you can use a sturdy door. Grab the pullup bar with an underhand grip shoulder width. Start in the finishing position for when you would regularly do a pullup. Then slowly take 6 seconds to lower your self. Repeat 6 times. That is one exercise you can do without weights but it doesnt cost much to invest in a dumbbell set with interchangeable weights. Good luck.
