The opposite of contraction in exercise against weight is relaxation, which refers to the lengthening of a muscle after it has contracted. In terms of muscle actions, this is often described as an eccentric contraction, where the muscle lengthens under tension, such as when lowering a weight. This phase is crucial for muscle control and helps prevent injury.
Isokinetic exercise utilizes machines that control the speed of contraction within the range of motion. Isokinetic exercise attempts to combine the best features of both isometrics and weight training.

Isotonic exercise (or muscle contraction) is when the muscle contracts and shortens giving movement (ie a bicep curl, lifting and lowering weight) Nearly all the training you do is Isotonic the opposite is Isometric, where the muscle contracts but des not shorten, giving no movement. Eg, Weightlifting, Lifting the weight up and down is isotonic Holding the weight still above the head is isometric
It is the force (weight) against which the muscles work.

An example of an isotonic exercise is a bicep curl, where a person lifts a weight by flexing their elbow, causing the muscle to shorten and lengthen throughout the movement. This type of exercise involves a constant load and allows for muscle contraction against resistance, which helps build strength and endurance. Other examples include squats and bench presses.
Regular exercise & green tea can help you to keep away from over weight.
Isometric exercise involves muscle contraction without any movement at the joint. This type of exercise helps to build strength and stability in specific muscle groups. Examples include planks, wall sits, and holding a weight in a static position.
To see eccentric contraction, look at the biceps curl with flexion around the elbow. As you lower a weight, you are working against resistance, letting the joint angle increase to lower that object under your control.The opposite is the concentric contraction were the arm is flexed upward to decrease the angle at the elbow.
Doctors and Nutritionist are against the Liquid Diet because it is a crash diet that does not help you continue to loose weight it makes it happen fast without exercise which is bad for your health.
