Isometrics: The Secret to Gaining Strength — Without Moving a Muscle

 

 

 

 

 

Some fitness trends make it seem like in order to get in shape, you have to bounce around, throw tires into the air, or leave a pool of sweat on the ground after every workout. But, believe it or not, you can build serious strength without even moving a muscle.

It’s called isometrics. In these exercises, your muscles tense up but don’t actually move. Say what?

Press your hands together in a prayer position as hard as you can for 10 seconds. You’ll feel tension in your chest and arms, but your arms won’t move at all. There — you just did an isometric exercise.

Holding a plank is another example you’re probably familiar with. And if you’ve ever taken a barre class, you know how hard it can be to simply hold still while your muscles are contracted.

In positions like these, the muscle fibers are activated, but since there are equal forces acting against each other, there’s no movement.

Compare this to picking up a 20-pound dumbbell to do biceps curls — the force of the weight pushing down is less than the force you’re using to lift the weight up.

With isometrics, you can take a break from jumping onto boxes, lifting heavy weights, or doing endless crunches (your lower back will thank you).

Isometric exercises have been found to have a range of health benefits. In 2016, for example, researchers found that an 8-week isometric exercise program was linked to lower blood pressure.Trusted Source

A 2014 study showed that older adults had an increased pain threshold after isometric exercises.Trusted Source

And if you’re into team sports, there’s good news for you too. A 2016 study found that lower-body isometric exercises improved jump height and kicking ability in soccer players.Trusted Source

Besides all that, you don’t need any equipment, and these exercises are actually fun! So if you’re looking to take a break from yet another set of heavy lifting, chill out and stay home.

Follow the tips below to get the most out of the isometrics workout.

Remember to squeeze

Since you’re not relying on movement to fatigue your muscles, you’ve gotta squeeze them — and we mean hard. The technical term for this is “maximal voluntary contraction,” which means you should tighten up your muscles as much as you can.

Breathe correctly

When doing isometric exercises, the natural tendency is to completely tense up and hold your breath. But do that and you’ll cut off the very thing you need to enhance your performance: oxygen. Plus, you’ll get red in the face and totally freak out your roommate.

Instead, try this. Place your right palm over your low belly and close your eyes. As you inhale, imagine you’re filling up a balloon behind your belly button (your belly should get rounder).

As you exhale, push air out through your nostrils. Notice how your low belly contracts. Keep inhaling and exhaling for five counts to get the hang of it. Feel your hand rise and fall with your breath. This is how to breathe during your isometric exercises.

Maintain proper form

You hear trainers talk about proper form all the time, since poor form can lead to injury. If you’re bench pressing 100 pounds with poor form, for example, the extra weight can cause damage to your shoulders or low back.

Form is very important in isometric exercises too. You don’t have a ton of weight pushing against you, so it’s difficult to get injured, but positioning is still important.

There’s also some research to suggest that testing out various angles can increase muscle strength.Trusted Source While the research is a bit older, it’s still sound, so be sure to switch up your exercises.

For example, when you place your arm at a 90-degree angle and tense up, you’re strengthening the biceps muscle at one length. Try positioning your arm at a 120-degree or 45-degree angle and see how that benefits your upper-body strength.

Mix it up

Now that you know you can work out with, like, zero equipment, should you throw out your running shoes and let the dog use your resistance bands as chew toys?

Tempting, but no way.

Aerobics are still better than isometrics for improving overall cardiovascular health. And if you’re looking for bigger muscles, lifting progressively heavier weights is the way to go.

Think of isometrics as another tool to add to your toolbox to help you live a fitter, healthier life — not the whole kit and caboodle. We recommend that you stick with a variety of exercise modalities so you’ll hit each of your fitness goals.

Isometric exercises

Ready to get started? Below are seven of our favorite isometric exercises to work your entire body.

1. Bent-over press against wall

 

 

 

 

 

 

Muscles worked: Shoulders

Start in a low lunge position. Place hands on the wall at about chest level. Lean into the wall and push. The farther down you bend, the more the exercise will target your shoulders. The more you stay upright, the more the exercise will target your chest.

Pro tip: Relax any tension stored in your face (like your brow and your jaw). Be sure to breathe throughout this exercise.

2. Prayer pose

 

 

 

 

 

 

Muscles worked: Chest

Place palms together. Your elbows can be flaring out or pointed toward the ground. Press your hands together. The tighter you press, the harder it will be.

Pro tip: Keep your shoulders level — raising them while you push can cause unnecessary strain.

3. High plank

 

 

 

 

 

 

Muscles worked: Core, back

Get into push-up position, making sure your spine is in a straight line. Press the floor away from you, broadening across your chest. Engage your core and breathe deeply.

Pro tip: Avoid lifting your butt too high or dropping your hips too low in this position.

4. Self-arm wrestling

 

 

 

 

 

 

Muscles worked: Biceps, triceps

Bend your right arm at a 90-degree angle. Grab your right hand with your left hand. Push them together as hard as you can. While your right biceps prevents your arm from dropping, your left triceps is trying to push your right arm down. Repeat on the other side.

Pro tip: People often tense their upper bodies in this position, so be sure to ease up on your shoulders.

5. Triceps extension against wall

 

 

 

 

 

 

Muscles worked: Triceps

Get into a lunge position with your fists on the wall at head level. Use your triceps to push your fists into the wall.

Pro tip: Avoid tensing your shoulders in this exercise. Also, don’t forget to breathe deeply.

6. Forearm plank

 

 

 

 

 

 

Muscles worked: Abs

Get into a forearm plank position. Keep spine is in a straight line and tighten abs as much as you can. Normally, people try to just hold this position, but contracting your abs will provide even more benefit for your core.

Pro tip: Instead of letting your butt fall down or hiking it too high, keep your shoulders, hips, knees, and ankles in line.

7. Low squat

 

 

 

 

 

 

Muscles worked: Glutes, quads, adductors

Stand with your feet about shoulder-width apart. Squat so thighs are parallel to the floor. Instead of just holding this position, try to squeeze your feet together. This will force your inner thigh muscles to contract even more.

Pro tip: One common mistake with this exercise is not sitting back far enough. To fix it, prevent your knees from going over your toes.

Perform 3 reps of each exercise below, contracting for 10 seconds in each rep. If your goal is fat loss, use less force (60 to 70 percent of your max contraction) and take short rest periods between sets (20 to 30 seconds).

If you’re doing it for strength and muscle growth, use more force (80 to 90 percent of your max contraction) and take longer rest periods between sets (45 to 60 seconds). Here are the exercises:

  • Bent-over press against wall
  • Prayer pose
  • High plank
  • Self-arm wrestling (each side)
  • Triceps extension against wall
  • Low plank
  • Low squat

This is a great routine to do first thing in the morning before you head to work or as a finisher at the end of a workout.
