Muscle weakness can be caused by a variety of factors, including age, inactivity, and underlying health conditions. While temporary muscle weakness may be caused by a tough workout or an illness, persistent muscle weakness could indicate a more serious issue. To boost muscle strength, health professionals recommend muscle-strengthening activities such as resistance or weight training, performed two or more days a week, with a focus on major muscle groups. Additionally, aerobic exercises performed at a vigorous intensity can also contribute to muscle strengthening. Seeking advice from a healthcare professional is important to determine the cause of muscle weakness and to receive guidance on appropriate treatment options.

What You'll Learn
Strength training
When starting a strength training programme, it is important to work with a certified trainer or physical therapist, especially if you are experiencing muscle weakness. They can guide you through the proper form and techniques for various exercises, ensuring safety and effectiveness. It is also crucial to start with moderate weights and gradually increase the load as you become stronger.
Some recommended exercises for building muscle strength include deadlifts, squats, bench presses, pull-ups, and planks. These compound exercises train multiple muscle groups and are a great way to start your workout when your body is fresh. You can also incorporate aerobic exercises like brisk walking, jogging, or swimming to boost your energy levels and overall health.
In addition to strength training, proper sleep, a balanced diet, and supplements like creatine and whey protein can support muscle growth and recovery. It is important to be patient as building muscle strength takes time, and noticeable results may take a few weeks to appear.

Resistance exercises
Resistance training can be done using free weights, weight machines, resistance bands, or your own body weight. Here are some examples of resistance exercises that you can do at home:
- Chair exercises: Choose a stable chair without wheels and sit with your feet flat on the floor and knees bent at a right angle. Avoid chairs with arms, as they restrict movement. From this position, you can do various exercises such as standing up slowly using your legs (not arms) or bending your elbows to perform bicep curls.
- Leg raises: This exercise can help strengthen your knees and legs. Stand with your back against a wall and your legs shoulder-width apart. Keeping your back and hips straight, raise your right leg to the side as far as comfortable. Return to the starting position and repeat with the left leg. You can also try raising your leg backward to work on different muscle groups.
- Wall push-ups: Stand at arm's length from a wall and place your hands flat against the wall at chest level with your fingers pointing upwards. Keep your back straight and slowly bend your arms, performing a pushing motion.
- Squats: Using your own body weight, you can perform squats. Stand with your feet shoulder-width apart and lower your body down as if you were about to sit back in a chair. Keep your knees and back straight and return to the starting position.
It is recommended to start with moderate weights or resistance and gradually increase the intensity over time. Aim for two to three sessions per week, allowing for rest and recovery between sessions.

Aerobic exercises
Some examples of aerobic exercises include walking, jogging, running, swimming, and cycling. These exercises are usually performed at a moderate intensity over a prolonged period, as opposed to high-intensity anaerobic exercises like weightlifting. For example, you could try alternating between leisurely rides and sprints on a bicycle to improve your leg strength and endurance. Swimming is another excellent option, as it is a low-impact activity that uses your arms and legs to propel you through the water, providing a good workout without putting too much stress on your joints.
To ensure a safe and effective workout, each session should include a warm-up and cool-down period of around 5-10 minutes each. The warm-up should involve a gradual increase in pace and intensity, avoiding static stretching, to increase blood flow to your muscles and reduce the risk of injury. The cool-down session should then involve a gradual decrease in pace, and this is when static stretching exercises are more appropriate.
It is recommended that you aim for at least 150 minutes of moderate-intensity aerobic activity per week, which can be accumulated through several shorter sessions. If you prefer more vigorous-intensity aerobic activity, you can meet your weekly target with just 75 minutes of activity. Vigorous aerobic exercises include activities like burpees, jumping rope, and playing tennis.

Flexibility exercises
To improve flexibility, you can try dynamic stretching, which involves moving your joints and muscles through their full range of motion. Examples of dynamic stretches include hip openers, butt kicks, and Frankenstein walks. You can also try static stretching, which involves sinking into a position and holding it for a period of time. Static stretches can be done immediately after a workout to help your mind relax and your body calm down. It is important to note that you should not feel strain, pressure, or pain in a joint when trying to stretch a muscle.
To get the most out of your flexibility exercises, focus on proper breathing. Diaphragmatic breathing, for example, can help you breathe more effectively and with less energy, as well as engage and strengthen your diaphragm and core muscles.
Additionally, foam rolling before a workout can help prepare your body for movement, while post-workout rolling can help you recover quickly for your next session. Staying properly hydrated will also help your muscles work optimally and respond to flexibility training.

Causes of muscle weakness
Muscle weakness can occur due to various reasons, some of which are temporary and normal, while others are more serious underlying medical issues.
In some cases, muscle weakness can be caused by a lack of physical activity or a sudden injury. For example, lifting something too heavy can cause a muscle strain or even a tear. It can also be caused by a lack of use, such as when a person is on bed rest for an extended period due to an illness or injury. In addition, muscle weakness can be a side effect of certain medications, such as corticosteroids and cholesterol-lowering statins.
Certain health conditions can also lead to muscle weakness. These include multiple sclerosis (MS), where the immune system attacks the protective layer surrounding nerve fibers, resulting in a breakdown of communication between the brain and other body parts. Other conditions include Guillain-Barré syndrome, a rare neurological disorder; myasthenia gravis, which can be exacerbated by pregnancy; and fibromyalgia, a chronic condition causing muscle pain and weakness.
Furthermore, muscle weakness can be caused by infectious conditions such as Lyme disease, meningitis, and HIV. Viral infections like the flu or COVID-19 can also lead to temporary muscle weakness, especially if they require prolonged bed rest.
Neurological conditions affecting how nerves transmit messages to muscles can also be a cause. These include cervical spondylosis, which puts extra pressure on the nerves, and botulism, a rare condition caused by exposure to botulinum toxin. Additionally, nervous system conditions such as specific types of migraines, especially hemiplegic migraines, can contribute to muscle weakness.
It is important to note that muscle weakness can sometimes be a sign of a more severe issue, such as a stroke or spinal cord injury, and it is recommended to seek medical attention if it lasts for more than a few days or interferes with daily activities.
