What Are The Best Isometric Leg Exercises?

Did you know that you can work your leg muscles without actually moving them? Yes, it is true, and it is possible through something called isometric leg exercise. This form of training has been gaining popularity in recent years and for a good reason.

The principle behind isometric exercises is that you burn fat as you strengthen and tone your muscles without causing the muscle fibers to contract or shorten. Before you start doing these exercises, however, let us first learn more about what you will be getting into.

What Is An Isometric Leg Exercise ?

Meaning of isometric

According to the dictionary, the word “isometric” means having an equal dimension or in physiology, any muscular action that develops tension without any muscle shortening. If that makes sense to you, let us break it down further.

So there are generally two ways that muscles contract: through isotonic and isometric contractions.

Isotonic contractions are those that happen when the length of the muscle fibers change. Like anything else, your muscles either shorten or elongate when you move.

People call muscle shortening, concentric motion, an example of which is the extension of the triceps and elbow extensor muscles. Eccentric motion or muscle elongation happens when a movement is towards the opposite direction of muscle contraction. As like when you flex your lower arm when you bend your elbow joint.

Why you should do isometric leg exercises

Isotonic exercises are those that we are most familiar with and use equipment like the best leg press machines. These are the movements where the muscle goes against some sort of resistance that it can overcome. In other words, you can use your strength to resist this load or weight, and the muscle either elongates or shortens to do so. This exercise helps in muscle activation.

This type of exercise muscle endurance and strength but may not do much for your cardiovascular health. A typical example of an isotonic exercise is lifting a barbell or a bag of groceries.

Isometric contractions, on the other hand, are those that occur without any change to the length of the muscles. Basically, you can still generate force and tension. But you are not performing any actual movement. 

Therefore, isometric exercises are those that require you to hold a pose or stay in a static position in contrast to performing repetitive motions. These usually include pilates and yoga poses.

Isometric exercises are better at raising your heart rate and taxing the cardiovascular system. Because of this, they cannot be done as often or as long as similar isotonic exercises.

Isometric exercises could also use resistance. As long as the muscle works against it is not strong enough to overcome it or cause a movement. When you use all of your muscle strength to resist this force without causing the attached joint to move, the muscle contracts but does not shorten or elongate.

Imagine doing squats with a very heavy weight. You start to do a few squats and then eventually come to a point when you are squatting down, but no matter how hard you engage your leg muscles and push your feet against the floor, you cannot stand back up. The first squats you performed were isotonic movements, and the last one was isometric.

What Are The Benefits Of Doing Isometric Leg Exercises?

There are a lot of advantages and benefits of doing isometric leg exercises. Here are some of the most notable ones:

1. ​They Take Less Time To Complete And Are Super Convenient

Don’t have enough time to exercise? No available machine or gym equipment that you can use? All of these are not problems when you are doing isometric exercises.

Essentially, all you need is your body weight, some space, and an optional yoga mat — no need for any special equipment or gym membership.

Also, isometric training is among the most convenient ways to work your muscles. You can do it anytime, anywhere. It also takes less time to complete. If you only have an afternoon break, you can still perform isometrics without sacrificing too much of your time.

2. ​They Help Improve Your Flexibility

If executed properly, isometric exercises are great for enhancing your flexibility. In doing so, they help improve your performance in other activities. This also significantly reduces your risk of getting injured.

3. ​They Promote And Boost Muscle Strength

Like any muscle training, isometric exercises are very good in developing muscle strength and endurance. They do this by engaging all of the motor units of your muscles at the same time, leading to leaner and stronger muscles.

When doing isometric exercises, you hold intense stationary positions without moving any part of the body. This allows you to contract target muscles against your own body weight and increase their strength.

4. ​They Are Low-impact

Isometric exercises are also great because they are safe and pose a minimal impact on the joints. This way, you can improve your flexibility, endurance, and strength without causing too much stress on the body.

In fact, many people perform isometric exercises during recovery from intense workouts. These help fix muscle imbalances in critical areas like the calves, back, hips, and quads.

5. ​They Help Speed Up Recovery From Injuries

Isometric exercises are static, low-intensity, and low-impact. That’s why these exercises are perfect for people who have suffered or are recovering from injuries. Not only shorten recovery time but they also strengthen stabilizer muscles to protect the injured muscles and prevent further damage.
