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 youâre performing the dumbbell fly exercise, your biceps brachii muscles isometrically contract to hold your elbows in a slightly bent position. The biceps run down the front of your upper arm, all the way from your shoulders down to the top of your lower forearm bone. Theyâre responsible for bending your elbows.
