This is the type of muscle fiber in your body that allows for short bursts of strength or speed, but quickly fatigue.

The human body is able to adapt muscle fiber types, based on strength development training.

The type of exercise where no movement takes place while a force is being exerted against an immovable object.

The type of exercise where the exercises are performed on machines that keep the velocity constant throughout the range of movement (preventing the performer from moving faster, no matter how much force is exerted).

The type of exercise where resistance is raised then lowered.

The movement that occurs when the muscle shortens while producing force (contracting the muscle). This happens when you are raising the weight during a biceps curl.

The movement that occurs movement when the muscle lengthens while producing force. For example, when you're lowering the weight back down during a biceps curl.

The type of exercises where the segment furthest away from the body — known as the distal aspect, usually the hand or foot — is free and not fixed to an object.

The type of exercises where the resistance the segment furthest away from the body — known as the distal aspect, usually the hand or foot — is fixed, or stationary.

The type of exercise in which muscles exert maximum force in short intervals of time, with the goal of increasing power (speed-strength).

Which of the following are possible ways to strength train?

This fitness principal is a form of strength training in which you move quickly from one exercise to a separate exercise without taking a break for rest in between the two exercises.

This type of strength training that involves a series of high intensity workouts interspersed with rest or relief periods.

Toning muscle means to reduce the appearance of body fat by tightening up the muscles and giving them shape. Bulking up means to increase muscle mass and make the muscles bigger. Which safe and effective strength training strategies should one use to accomplish this?
