Can you do tricep workout after shoulder workout?
The triceps muscle belongs to your upper hand's major extensors. Shoulder specified workouts don't really train your triceps, but rather your deltoid muscle. Push-ups are always recommended for the training of your triceps and biceps.
What is the ability of muscles to be stretched?
When a muscle moves, several things have to happen at once. In the simplest form, let's say you are extending you hand in friendship and thus "stretching" your arm outward. The primary skeletal muscles in this movement would be the biceps brachii and it's companion, the triceps brachii. According to the 3rd Law of Motion, for every action there is an equal and opposite reaction. If the biceps contracts, the triceps relaxes and vice versa. To extend your arm the triceps will be in contraction and the biceps will be relaxed or "stretched out".

What happens when you bend your arms?
When you bend your arms, the muscles in your biceps contract, causing your forearm to move towards your upper arm. This movement occurs at the elbow joint, which allows for the bending motion. Additionally, bending your arms can help you lift, push, or pull objects.
Why do you need both biceps and triceps to move the lower arm up and down at the elbow?
Because muscles can not push, they can only pull (contract). So while your biceps contract to pull the arm up into a flexed position; the triceps are necessary to pull the arm back down into an extended position. Skeletal muscles or groups of skeletal muscles must work in pairs. These pairs are called "antagonistic" muscles; while one group is contracting, the other group is relaxing. You can easily feel this action in your arm. With your right arm extended, place you left hand on your right biceps. Flex your arm (as if to make a big muscle) and you will feel the biceps brachii tighten and bulge somewhat; we are familiar with this. Now, place your left hand on your triceps and straighten the right arm completely (extra straight) and you should be able to feel the triceps brachii tighten. Although aided by gravity, the triceps MUST contract to straighten the arm.
What is the function of the biceps?
The biceps brachii is the muscle on the front of your upper arm. Its purpose is to pull bend your arm at the elbow (flexion).It is one of an antagonistic pair of muscles. The other muscle is the triceps brachii on the back of the upper arm. It straightens (extends) your arm at the elbow.The biceps are used to flex the lower arm up to the upper arm. They also allow the wrists to suppinate.It helps in flexioning the forearm against the arm
What part of the body does the biceps move?
The biceps muscle is located in the front area of the upper arm. The biceps muscle helps to stabilize the large bone in the upper arm (the humerus) in the shoulder socket. It also helps to accelerate and decelerate the arm during overhead activities, like tennis or pitching. The biceps tendons keep the biceps muscle attached to the shoulder at one end and the elbow at the other end. Tendons are strong cord-like structures that connect each end of the biceps muscle to bones. At one end of the biceps muscle, tendons connect the biceps to the shoulder in two places. At the other end of the muscle, tendons connect the biceps muscle to the smaller bone (radius) in the lower arm. Source:AAOS

What muscle synergist is used for supination of the hand?
The biceps brachii muscle acts as a synergist for supination of the hand. It works in coordination with other muscles, such as the supinator muscle, to rotate the forearm and bring the palm facing upwards.
