12 Best Isometric Leg Exercises For Safe & Productive Muscle Stimulation

Isometric contractions, also known as static strength training, can help build balance, muscle, strength, and range of motion.

Unlike isotonic muscle actions, where the muscles visibly change the length and simultaneously develop tension, isometric exercises activate the muscles by generating force without visibly changing muscle length or moving the joints.

Isometric exercises focus on the static engagement of muscles without movement of the joints. These low impact exercises are used during recovery periods and allow the muscles and tendons to slowly advance on to more vigorous movements using resistance bands or even weights.

A typical example of an isometric exercise is holding a plank position for a set amount of time.

When performing an isometric workout, there is no impact making this form of training especially suitable for rehab and injury prevention.

Generally speaking, there are three different ways in which a persons muscles contract and move; concentric movements, eccentric movements and isometric.

If we take the squat as example, the concentric part of the squat is when you move up with the eccentric part being when a person moves down.

An isometric squat is when a person reaches the bottom of the movement and simply holds for a few seconds.

However, it doesn’t just apply to someone lifting heavy weights. As isometric exercise is holding either a weight or just your bodyweight for a period of time, helping to increase time under tension.

Below are 12 effective isometric movements that specifically target the legs .

Benefits Of Isometric Training

Personal trainers, rehabilitation facilities, and coaches use isometric training to prepare athletes and rehabilitate general populations physically.

This type of training can be an effective way to maintain muscle tone, improve flexibility and athletic performance and can offer a significant reduction to painful tendons.

Overall, isometric exercises are beneficial for improving muscular endurance.

When compared to dynamic training, which is best for increasing muscle mass, isometric exercises have shown to be a better form of exercise for physical rehabilitation.
