Building big arms is a common gym goal—but you'll need to focus on these four muscles: the deltoids, biceps, triceps, and forearms.
A simple way of demonstrating that the effect is an illusion is to hold a small pebble (say, 0.33 inches or 8.4 millimetres wide) at arm's length (25 inches or 64 centimetres) with one eye closed, positioning the pebble so that it covers (eclipses) the full Moon when high in the night sky.

Longer-term hypertrophy occurs due to more permanent changes in muscle structure. Hirono et al. explained the causes of Muscle swelling: [10] "Muscle swelling occurs as a result of the following: (a) resistance exercise can increase phosphocreatine and hydrogen ion accumulations due to blood lactate and growth hormone production, and
The biceps or biceps brachii (Latin: musculus biceps brachii, "two-headed muscle of the arm") is a large muscle that lies on the front of the upper arm between the shoulder and the elbow. Both heads of the muscle arise on the scapula and join to form a single muscle belly which is attached to the upper forearm.
Baby bumps can change in size and shape in as little as a few hours, and have been known to appear larger at night than during the day.
Biceps is the major supinator (drive a screw in with the right arm) and pronator teres and pronator quadratus the major pronators (unscrewing) — the latter two role the radius around the ulna (hence the name of the first bone) and the former reverses this action assisted by supinator. Because biceps is much stronger than its opponents ...
