Table 1. The Type of Resistance Exercise Training Program.

Type	Description	Examples
Isometric RE	A static contraction of muscle against external resistance without change in its length or joint motion	Yoga poses such as Plank or the Warrior variations, side bridge, hundred breaths exercise, pushing against a fence
Isotonic RE	A dynamic exercise against resistance as a muscle lengthens or shortens through the available range of motion
	- Concentric contraction: an active muscle undergoes shortening while overcoming external resistance	Contraction of biceps curl with fixed weight
	- Eccentric contraction: an active muscle undergoes lengthening while being overcome by an external resistance	Extension of quadriceps during knee bend
Isokinetic RE	An active exercise in which a muscle or group of muscles contracts against a controlled accommodating resistance that is moving at a constant angular velocity	Fitness machines (e.g., stationary bike, bench press machine, bent-over row), dynamometer
