Why Building Muscle Matters for PCOS

Key Takeaways

• Muscle tissue plays an important role in glucose metabolism and insulin sensitivity.
• Strength training can help maintain muscle mass and support metabolic health.
• Resistance exercise may also support bone health and physical function.
• A balanced exercise routine can include both strength training and aerobic movement.

Exercise is often recommended as part of managing polycystic ovary syndrome (PCOS), yet many of us feel unsure about where to start.

Cardio-based exercise such as walking, cycling or swimming is frequently suggested. While these forms of movement can be beneficial for overall health, high intensity endurance cardio can actually be detrimental to those of us with PCOS. Probably the most important component of exercise for PCOS is often overlooked: strength training.

Building and maintaining muscle mass may play a meaningful role in supporting metabolic health, improving insulin sensitivity and maintaining long-term physical wellbeing in people with PCOS.

Understanding how muscle interacts with hormones and metabolism can help explain why strength-based exercise may be particularly helpful.

The Role of Muscle in Metabolic Health

Skeletal muscle is one of the most metabolically active tissues in the body. It plays an important role in how glucose is used and stored.

After eating carbohydrates, glucose enters the bloodstream. Muscle tissue acts as one of the main sites where glucose can be taken up and used for energy.  For individuals with PCOS, insulin resistance is common. This means the body needs to produce more insulin to move glucose into cells effectively.

Strength training helps increase muscle mass and improve the ability of muscle cells to respond to insulin. Over time, this may support improved metabolic function.

Exercise can also stimulate glucose uptake independently of insulin. In simple terms, when muscles contract during activity, they can absorb glucose directly from the bloodstream.

This is one reason why regular movement is often recommended as part of a lifestyle approach to supporting metabolic health in PCOS.  You can read more about insulin resistance and PCOS in our article on understanding insulin resistance in PCOS.

Strength Training and Hormonal Balance

Strength-based exercise may also influence hormone regulation in several ways.

Research suggests that resistance training may help improve insulin sensitivity and body composition, both of which are important factors in PCOS management.

Muscle tissue also contributes to resting metabolic rate. This refers to the number of calories the body uses at rest to maintain essential functions.  Maintaining muscle mass can therefore help support energy balance over time.

Strength training may also support bone health. When muscles contract against resistance, they create mechanical stress on bones. This stimulus encourages bone remodelling and may help maintain bone density.

This connection between muscle and skeletal strength is particularly relevant when considering the long-term health of individuals with PCOS. You can learn more in our article on bone health and PCOS.

What Does Strength Training Look Like?

Strength training simply means using resistance to challenge muscles. This doesn’t necessarily require access to a gym. Resistance can come from bodyweight exercises, resistance bands, free weights or weight machines.

Examples of strength-based exercises include:

• Squats
• Lunges
• Push-ups
• Resistance band exercises
• Weight training with dumbbells or kettlebells

Research suggests incorporating strength training two to three times per week alongside other forms of movement such as walking or cycling can be beneficial in managing PCOS symptoms.

For those new to exercise, starting gradually is important. Short sessions focused on learning proper technique can be more beneficial than intense workouts that are difficult to maintain.

And consistency tends to be more important than intensity when building sustainable habits.

Overcoming Common Barriers

Many individuals with PCOS find starting to exercise really tough. Fatigue, joint discomfort, low motivation or previous negative experiences with dieting and exercise can all make movement feel really hard. But strength training does not need to be extreme or time consuming to be helpful.

Short sessions, supportive environments and gradual progress can help make movement more manageable and sustainable.

Focusing on how exercise supports energy, strength and long-term health, rather than solely weight loss, may also create a more positive relationship with movement.

Supporting Exercise Through Nutrition

Nutrition plays an important role in supporting muscle health and recovery.  Adequate protein intake provides the amino acids needed for muscle repair and maintenance. Many people with PCOS may benefit from distributing protein across meals throughout the day.

Micronutrients such as vitamin D, magnesium and omega-3 fatty acids may also support muscle function and recovery. Hydration and sufficient energy intake are also important, particularly for those increasing their activity levels.

A Balanced Approach to Movement

There is no single exercise approach that works for everyone with PCOS.

A balanced routine that includes strength training, low intensity aerobic movement and rest may help support metabolic health, muscle maintenance and overall wellbeing.

Finding forms of movement that feel enjoyable and sustainable is often the key to maintaining long-term habits.

If you are unsure how to adapt exercise to your individual needs, working with a qualified health professional can help you create a plan that feels realistic and supportive. Why not book a call with us to find out more?
