Do bulging biceps give you more strength in your arms to lift your body weight in break dancing?

Answer 1

Yes and no.

Bulging biceps are used for pulling motions that bend your elbow, such as "curl" lifts, tug-of-war, hugging, and drinking a glass of water. They aren't terribly helpful for pushingmotions, like push-ups, patty-cake, punching your pillow, or break-dancing; your triceps (not biceps) are the primary upper-arm muscles used in these activities.

But there's more to it than that.

In order to have bulging biceps, you will also need to train your triceps. In order to have strong triceps (which will help you in break-dancing), you will need to develop your biceps. These muscle groups work opposite each other, and you will have an unbalanced system if you try to do one without the other.

Imagine someone with massive, bulging biceps, but very weak and tiny triceps; not only would this person look pretty silly, but they might not even be capable of straightening their arm all the way, because of the constant tension created by the muscle tone of the well-developed biceps (this is also the reason why full range of motion should be used during all muscle-building exercises).

In short, biceps are not the primary muscles used in break-dancing, but proper development of the upper arms (and all other muscle groups, really) will result in bulging biceps anyway.
