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.
The other muscles that make up the elbow flexors aren't the focus for now. The biceps brachii has two heads running parallel to one another along your upper arm. The short head runs on the inside of the arm, closest to the chest, and adds to the thickness when viewed from the front. The long head runs along the outside of the arm and forms the peak when flexed.
