What Is Isokinetic Exercise?

Isokinetic refers to the idea of consistent speed. No matter how heavy you are lifting, the pace at which you do the movement should stay the same. This refers to the intensity of the resistance.

Certain exercise machines will do this for you. They do this by controlling the resistance curve so that the point at which the resistance is easy or hard is more controlled. 

What Is Isometric Exercise?

Isometric exercise refers to the idea of producing force without moving any of your joints. This can be done in things like a plank or a wall sit. This can be just as effective, but you are not moving during the exercise. 

Instead, you are using your muscles to maintain a certain posture, allowing gravity to do the work.

When Should You Do Isotonic Exercise?

Isotonic exercise is the center of many different training programs. It is important for building muscle, and it will help with the development of your athleticism in lots of ways.

More Movement Is Better

Your joints are designed to move and, to make this movement happen, your muscles need to contract and stretch. The process of movement is known as a flexion-extension cycle, and it is essential for developing flexibility and strength. 

It is important to train your muscles isotonically because if you do not work out these muscles properly, you will lose them. You have to use these muscles properly to strengthen them.

Burn Lots Of Calories 

If you are hoping to lose weight, it is important to consider how many calories you will burn through certain types of exercise. Isotonic exercise is a great way to burn calories.

It burns more calories than training which doesn’t include much movement. This is because more energy is used up when you are moving around than when you are not.

While you may not burn many more calories in this way, it is worth noting.

When it comes to your chest, there are lots of isotonic exercises that you can choose from. A bench press is a great example of one of these exercises. Benching is isotonic because it requires you to move your shoulder and elbow joints to carry out the motion. 

To do this exercise, lie down on the bench and grab the bar around the width of your shoulders. Then, draw out the bar so that it rests above your shoulder.

After you have done this, brace your body and lower the bar down to your chest. Then push it back up to the starting position.


Isotonic exercise is very important when it comes to working out your shoulders. You can perform things like the seated dumbbell shoulder press as this will engage all of the muscles in the motion. 


It is possible to carry out isotonic back exercises in vertical or horizontal positions. These options will work the same muscles but the setup is slightly different.


When it comes to isotonic exercises for your legs, you’ll want to carry out more than one exercise. The back squat and the Romanian deadlift are two examples of this.
