5 Examples of Isometric Exercises for Static Strength Training

Isometric Exercises

Isometric training is essentially a fancy way to categorize exercises that recruit muscles and exert tension without actually lengthening or shortening the muscle. In other words, your muscle is flexed, but it’s not expanding and compressing. It’s a stagnant way of placing a demand on a desired muscle or group of muscles.

This type of training includes a number of moves that can target your entire body. As always, you can make the best use of your time if you perform moves that engage both your upper body and lower body at the same time. Any of the exercises listed below can be combined with an upper or lower body component to make sure all major muscle groups are being worked.

Isometric exercises are ideal for those with limited workout space, existing knee discomfort, or anyone simply needing a change in their typical fitness routine. Because these moves are improving strength in one body position, they should only serve as a compliment to a more dynamic exercise regimen.

According to the Mayo Clinic, isometric exercises are often prescribed as a path to healing for arthritis and rotator cuff injuries.

Wall Sit

Wall sits focus on improving the strength in your thighs.

Equipment needed: none

Muscles worked: quadriceps, hamstrings, and glutes

  1. Stand about 2 feet away from a sturdy wall, leaning your back against it.
  2. Sink your bottom down so that your legs form a 90-degree angle. Your body position should resemble the same posture you have when sitting in a chair.
  3. Hold this position for 15 seconds.
  4. Perform 5 rounds of a 15-second hold.

To maintain this position, you will feel your thighs becoming tighter and more fatigued. Experiment going back and forth between driving your weight down through your toes, then your heels. Driving down through your heels will target your glutes, while driving down your toes will target your quadriceps. Just be sure not to let your knees go our past your toes, and when you put weight on your toes, don’t put too much pressure on the knees.

Plank Hold

The plank hold is an effective way to engage the entire anterior portion of your body.

Equipment needed: none, yoga mat optional

Muscles worked: abdominals, quadriceps, and the anterior portion of the deltoid

  1. Start with your body in a horizontal position with your weight on your toes and forearms.
  2. Be mindful to flex your hips forward (butt clenched) and don’t let your hips sink.
  3. Hold this position for 30 seconds. You should feel the most tension in your shoulders and core.
  4. Perform 4 rounds of 30-second holds.

Overhead Hold

Overhead holds challenge the muscular endurance of your shoulder girdle.

Equipment needed: Light to medium weight required. Start with a 15-pound plate, dumbbell, or kettlebell.

Muscles worked: Anterior, posterior, and superior portions of the shoulder.

  1. Extend your arms above your head and hold the weight steady.
  2. Make sure to keep your arms fully extended. Bending your arms will engage different muscles (your biceps and triceps).
  3. Hold the weight over your head for 30-second intervals.
  4. Perform 5 rounds.

Increase the challenge by standing on one leg while holding the weight.

  1. Sit on your bottom with your knees bent and feet flat on the floor.

  3. Hold this position for 15 seconds.
  4. Perform 5 rounds.

The Takeaway

With so many different ways to exercise, it can be hard to choose which path is right for you. Isometric exercises just may be the perfect addition to your workout routine if you:

  • experience chronic knee pain
  • are recovering from a knee surgery
  • are seeking a low-impact exercise as recommended by your doctor
  • are looking for a different kind of fitness challenge
  • have a shoulder injury

Always remember that these exercises can be adjusted to suit your current level of fitness. For example, if 15-second body holds are too challenging, bump it down to 10 seconds and then build up as you get stronger over time.

The idea is to push your limits without causing true injury. Soreness can be expected, but listen to your body if you experience excruciating pain.
