Abstract. Hyperbranched polymers are polymers based on A x B-monomers, ie, monomers having one B-functionality and two or more A-groups resulting in polymers with a potential branching point in each repeat unit.
Source(s): 30 years in sports medicine and clinical nutrition. The biceps brachii is a antagonist of the triceps brachii. If the triceps brachii will contract, the biceps brachii will stretch and vice versa. Pushups. I do about 500 per day (200 AM, 300 PM) and my arms aren't huge, but they're toned pretty well, I guess.
When it comes to building Big Bulging Biceps one area that most muscle heads never even consider is the Brachialis... This is a small muscle that runs underneath the biceps, and when fully developed can actually help push the peak of your biceps up higher and add lines and detail to your arms. This isn't to say that just training the brachialis alone will result in the massive sleeve stretching arms that you want.
