Flexing your muscles is more than just a way to show off the results of your workouts. It can also be a way to build strength and improve your mental and physical health. Muscle flexing, more accurately known as muscle contraction, creates tension that temporarily makes muscle fibres smaller or contracted. This can be done through isometric exercises, which strengthen muscles by keeping them still while they face resistance. For example, if you sit against a wall with your legs bent, you will feel tension in your quadriceps. This type of exercise can be particularly beneficial for those with injuries or high blood pressure. Additionally, flexing your muscles can help treat headaches, digestive problems, and insomnia. Progressive muscle relaxation (PMR) is a popular technique that helps control anxiety and depression by teaching individuals how to recognise and relax their muscles.

What You'll Learn
Muscle contraction and tension
Muscle flexing is more accurately referred to as muscle contraction. When you flex a muscle, you create tension that temporarily makes the muscle fibres smaller or contracted. This tension can stimulate muscle growth and strength. Progressive overload is built into this process, as stronger muscles can exert more force, increasing the challenge.
Isometric exercises, also known as isometrics, are a type of muscle-flexing exercise. They strengthen muscles by keeping them still while they face resistance. For example, in a wall sit, you will feel tension in your quadriceps. Isometrics can be beneficial for people with injuries because they are low-intensity and do not require joint movement. They can also help manage blood pressure and improve balance. However, they do not improve flexibility, so they should be combined with other exercises that involve a full range of motion.
Progressive muscle relaxation (PMR) is a technique that involves tensing and releasing muscles sequentially to help you recognise the difference between tension and relaxation. It can be used to treat anxiety, insomnia, migraines, and symptoms of stress. When practising PMR, it is important to pay attention to your breathing patterns and try to block out negative thoughts.

Isometric exercises
During isometric exercises, the length of the muscle and the angle of the joint do not change, although the contraction strength may vary. This is in contrast to isotonic contractions, where the contraction strength remains constant while the muscle length and joint angle change.
Isometrics are an excellent way to build muscular endurance, or the ability to sustain exercise for a longer period of time. They can also promote muscular strength, defined as the muscle's ability to exert force against resistance.
Some examples of isometric exercises include:
- Planks
- Wall sits
- Glute bridges
- Holding a crouched position
- Pressing the palms of the hands against each other
- Holding a squat position
- Calf raises

Progressive muscle relaxation (PMR)
The first step in PMR is to create tension in specific muscle groups, one at a time, and notice what tension feels like in that body part. This can be done by sitting or lying down in a quiet room and applying muscle tension to a particular body part, such as the left thigh. The key is to tense each muscle group and hold for about 5 seconds. It is important to pay attention to your breathing patterns during this step, taking deep, slow breaths, and blocking out any negative thoughts.
The second step is to release the muscle tension and notice what a relaxed muscle feels like as the tension drains away. This is done by exhaling and letting the muscles fully relax for 10 to 20 seconds before moving on to the next muscle group. It is recommended to start at one part of the body and move systematically, either from head to toe or vice versa. For example, one might begin by lifting and lowering their toes, then move on to their calf muscles, and so on.
PMR has been found to be effective in treating anxiety, insomnia, migraines, tension headaches, high blood pressure, and chronic pain. It can be a useful tool for learning about the body and its signals and can be easily incorporated into one's daily routine, requiring only about 10 to 30 minutes per day to practice.

Boosting mental and physical health
Muscle flexing, also known as muscle contraction, is more than just a way to showcase the results of your strength training. It can help boost your mental and physical health in numerous ways.
Physical Health Benefits
Muscle flexing with isometric exercises can be an excellent way to build strength and endurance. Isometrics involve contracting your muscles and keeping them still while they face resistance. For instance, when you sit against a wall with your legs bent, you create tension in your quadriceps. This form of exercise is particularly beneficial if you're recovering from a joint injury, as it doesn't put extra stress on the joints and can be less painful than traditional strength training. Additionally, isometric exercises improve your balance and core stability, especially with exercises that support your spine and trunk. They are also time-efficient and don't require any equipment or a dedicated workout space.
Mental Health Benefits
Flexing your muscles can have a positive impact on your mental health by helping you relax and reduce anxiety. Progressive muscle relaxation (PMR) is a technique where you tense and release specific muscle groups, helping you recognize the difference between tension and relaxation in your body. This can be particularly beneficial if you're experiencing anxiety or stress, as it teaches you what muscle relaxation feels like and aids in improving mental health, digestion, and sleep. PMR has also been shown to help patients with COVID-19 manage their anxiety and sleep disturbances. Furthermore, muscle flexing can improve blood circulation, which can alleviate headaches and symptoms associated with high blood pressure and digestive issues.

Building muscle strength
Muscle flexing, or muscle contraction, is a way to build muscle strength. When you flex your muscles, you create tension, making the muscle fibres contract. This tension can stimulate muscle growth.
There are various exercises that can help build muscle strength. Isometric exercises, also known as isometrics, are a popular way to build strength. These exercises strengthen muscles by keeping them still while they face resistance. For example, you can try a wall sit, where you sit against a wall with your legs bent as if there's a chair beneath you. This creates tension in your quadriceps, helping to make them stronger. Planks, glute bridges, and wall sits are also good isometric exercises to try.
Progressive muscle relaxation (PMR) is another technique that can help build muscle strength. PMR is a deep relaxation technique that involves tensing and relaxing specific muscles in your body. This helps you learn what it feels like to be tense and relaxed, improving your mental health and blood circulation.
In addition to exercises, certain foods can help build muscle strength. Protein-rich foods such as eggs, wild salmon, Greek yoghurt, sunflower seeds, and lean jerky are great options. Spinach is also an excellent choice, as it contains iron and nitrates to promote muscle growth.
Finally, weight training can be an effective way to build muscle strength. When performing resistance training, such as lifting weights, it's important to choose a weight that challenges you. Start with a weight that can be lifted around 10 times, with the last few repetitions being difficult. As you get stronger, gradually increase the weight to continue challenging your muscles.
By incorporating these exercises, techniques, and dietary choices, you can effectively build muscle strength and improve your overall health.

Frequently asked questions
Uncontrollable muscle movements are known as myoclonus. Myoclonus is a brief, sudden muscle movement that can feel like a twitch, jerk or spasm. It can be caused by neurological conditions, such as epilepsy, or by damage to the brain, spinal cord or peripheral nerves. Myoclonus can also be caused by certain medications, exercises or injuries. In some cases, it can be a sign of a more serious condition. If you are experiencing myoclonus, it is important to consult a healthcare professional.
Muscle flexing, also known as muscle contraction, can be a way to build strength. Certain exercises, such as isometric exercises, strengthen the muscles by contracting them and keeping them still while they face resistance. For example, sitting against a wall with your legs bent will create tension in your quadriceps, which can help to strengthen the muscle.
Muscle spasms are common and can be unpredictable, but there are some steps you can take to reduce your risk. These include performing flexibility exercises, staying hydrated, avoiding extreme heat during exercise, maintaining a healthy weight and wearing properly fitting shoes. If you are experiencing frequent muscle spasms, it is recommended to consult a healthcare professional.
