Flexing your muscles is more than just a show of your strength training program results. It can also be used to gain strength.

Muscular flexing is more appropriately known as muscle contraction because when you flex your muscles, you create stress that causes the muscle fibers to shrink or contract temporarily.

Isometric exercises (or isometrics) are muscle-strengthening workouts that contract and hold the muscles stationary as they confront resistance. So, rather than moving weights, the muscle is strengthened by remaining stationary.

For example, if you sit against a wall with your legs bent, as if there’s a chair beneath you, you’ll experience quadriceps stress. This tension is an illustration of how flexing your muscles can help strengthen them.

This article will look at the benefits of muscle flexing, when it is most beneficial, and examples of flexing exercises you may use into your routine.

What are the benefits of flexing muscles?

When included in your workout plan, muscle flexing with isometric exercises gives a lot of benefits.

  • These workouts may help reduce systolic and diastolic blood pressure.
  • They enable strength training even when typical muscle actions are uncomfortable. When the shoulder joint moves in specific directions while recovering from a torn rotator cuff, for example, it might be uncomfortable.
  • Balance and core stability can be improved by exercises that support your spine and trunk.
  • These exercises do not necessitate the use of any equipment or a training environment. Dumbbells or resistance bands can be used for some isometric exercises.

Is it possible to develop your muscles simply by flexing them?

Simply flexing your biceps in front of the mirror will not strengthen them.

Certain isometric exercises, such as planks, wall sits, glute bridges, and others, can, however, be effective strength training exercises to include in your routine.

However, because isometric workouts keep your muscles immobile, the muscle being worked only strengthens in one position.

Flexing exercises should be performed in a number of positions and across a range of motions to provide a more comprehensive workout for a specific muscle or muscle group.

Isometric workouts may assist increase strength, but they do not improve muscle flexibility. The reason behind this is that the muscle does not have to lengthen in order to move because it is using force and momentum. Isometric exercises are usually effective at building strength, but do not offer much benefit for endurance since they do not require any type of movement outside of the static contraction.

Isometric moves can be used in the beginning stages of a workout when a person has just started to exercise, or as a means of increasing strength at the end of a workout. An isometric exercise uses force on an immobile object in order to create tension. A muscle contraction is performed by contracting the targeted muscles against a force that does not move it, but instead can be applied only in one place.

When is flexing most beneficial?

  • Muscle flexing can be especially beneficial when recuperating from an injury to a joint, such as the shoulder or knee. Holding your muscles flexed in one position places no additional strain on the joint. Isometric exercise may be perfect and less painful than other strength training activities if you have a joint injury or arthritis.
  • Isometric exercises don’t take long, so even if you just have a few minutes, you can easily fit in many muscle building exercises, and you don’t even need any equipment.
  • Isometric exercises may also help prevent blood pressure spikesTrusted Source, so if you have high blood pressure or are at risk of hypertension, these exercises may be very beneficial.

Exemplifications of flexing exercises

Exemplifications of flexing exercises

There are several isometric exercises that can work the muscles all over your body. These are easy workouts that can help you build strength in several of your key muscle groups.


This exercise has grown in popularity, in part because it can be done anywhere and also because it works your core muscles extremely well.

  • A simple plank is performed by resting just on your forearms and toes, keeping your buttocks squeezed, your torso straight, and your abdominal muscles engaged.
  • Try to complete 3 or 4 30 second planks every day. If it is too difficult, start with 20 seconds each.

Wall sit

This exercise engages your quads, hamstrings (the muscles in the rear of your thighs), and glutes (the muscles in your buttocks).

  • Place your back against a wall and your feet about 20 inches away.
  • Lower your buttocks to establish a 90-degree angle with your legs.
  • Hold for 15 seconds before standing up.
  • Pause for a few seconds before performing four more 15-second sits with short intervals in between.

Bent-over wall press

This exercise will strengthen your chest and shoulder muscles.

  • Stand in a lunge position, one foot in front of the other, facing a wall.
  • Bend toward the wall, pushing flat against it with both hands.
  • Hold for 20 seconds, then pause and repeat 4 times more.
  • The exercise works your chest muscles when you’re upright, but it benefits your shoulders more when you lean forward.

Biceps and triceps squeeze

This workout targets both the biceps and the triceps.

  • Bend your left arm in front of you at a 90-degree angle, with your left palm facing up.
  • Push your right hand down into your left hand while pushing your left hand against your right hand.
  • Hold for 20 seconds, then pause and switch arms.
  • Repeat 3 or 4 times on each side.

Adductors squeeze

This exercise works the adductor muscles, which go from your pelvis to your femur.

  • Lie on your stomach with your feet flat on the ground and your knees bent.
  • Squeeze your knees together while holding a basketball or comparable item.
  • Pause after a few seconds of holding.
  • Perform 8 to 10 repetitions.
  • Work your way up to 2 or 3 sets of 10 reps per day.

Body hold

This workout increases core strength and stability.

  • Sit on the floor, knees bent and feet flat on the ground.
  • Raise your arms while straightening your legs to form a “V” shape with your body.
  • Hold this position for 15 seconds, then pause and repeat four times more.

Neck squeeze

  • Place your palm against your forehead while standing upright with your feet shoulder-width apart.
  • Gently press your palm against your forehead while using your neck muscles to resist. Hold the position for 10 seconds.
  • Pause, then repeat with your hand pushing the back of your head.
  • Pause and repeat, but this time place your hand against the right side of your head and then the left.
  • Perform four rounds of these neck-strengthening exercises.

Safety tips

Although muscle flexing exercises are typically safe to practice, there are some safety concerns to keep in mind.

While holding a muscle flexing stance, you may be inclined to hold your breath. However, this is risky and might result in an unhealthy increase in your blood pressure.

When undertaking strength or resistance training, always maintain inhaling and exhaling and try to relax the muscles that aren’t immediately involved in the action.

The bottom line

Muscle flexing with isometric workouts is one method of increasing muscle strength. If you have an injury that makes mobility painful, these exercises may be extremely beneficial. According to research, these workouts may also be beneficial if you have high blood pressure.

Because muscle flexing does not improve range of motion or flexibility, it should be done as part of a larger resistance-training program.

Check with your doctor, as with any new workout plan, to ensure that these types of exercises are safe for you.
