The principal muscles that carry out work are known as ___ and can be recognized by a certain __________ .
The primary muscles that perform work during a specific joint action are referred to as agonist's muscles. Agonists' muscles are also known as prime movers because they are primarily responsible for generating the force required to perform a particular movement or joint action.
Agonists' muscles contract concentrically, meaning they shorten and produce the desired movement at a joint. For example, during a bicep curl exercise, the primary agonist muscle is the biceps brachii, which contracts to flex the elbow joint, resulting in the lifting of the weight
For a particular workout, the warm-up is the ____ period.

The skeletal system's bones have the following fundamental functions.
A basic function of certain bones in the skeletal system is to provide a site for the production of red blood cells. This process is called hematopoiesis and takes place in the bone marrow, a soft tissue found inside certain bones.
The varied intensity or spontaneous training approach is referred to as.
Intermittent training refers to a training method that involves alternating periods of work and rest or low-intensity recovery. This method is commonly used in various forms of interval training, where short bursts of high-intensity exercise are followed by periods of active recovery or rest. The purpose of intermittent training is to challenge the cardiovascular system, improve endurance, and increase the overall intensity of the workout.
