Thyroid conditions can significantly impact how your body feels and functions. Whether you’re dealing with an underactive thyroid (hypothyroidism) or an overactive thyroid (hyperthyroidism), symptoms like fatigue, weight changes, and reduced exercise tolerance are common.

While medication is often essential, exercise can play an important role in helping manage symptoms and improve overall wellbeing.

Understanding Thyroid Function

The thyroid is a small gland that regulates metabolism — essentially how your body uses energy.

When thyroid function is disrupted, it can affect:

• Energy levels

• Heart rate

• Muscle function

• Body weight

• Temperature regulation

This is why many people with thyroid conditions feel either constantly fatigued or unusually restless.

How Exercise Helps

Exercise doesn’t directly “fix” thyroid hormone levels, but it can improve how your body responds to them.

It does this by:

1. Improving Energy Levels

Fatigue is one of the most common symptoms of thyroid disorders.

Regular, structured exercise can help:

• Improve mitochondrial function (energy production)

• Reduce feelings of fatigue

• Increase overall activity tolerance

Importantly, exercise should be introduced gradually to avoid excessive fatigue.

2. Supporting Muscle Strength

Thyroid conditions can lead to muscle weakness or reduced muscle mass.

Strength training helps to:

• Maintain muscle tissue

• Improve force production

• Support joint stability

This is particularly important for long-term physical function.

3. Assisting Weight Management

Changes in metabolism can make weight management challenging.

Exercise can help by:

• Increasing energy expenditure

• Supporting lean muscle mass

• Improving metabolic efficiency

The focus should be on consistency rather than intensity.

4. Supporting Mental Health

Thyroid disorders are often linked with mood changes, including anxiety and low mood.

Exercise has well-established benefits for:

• Reducing stress

• Improving mood

• Enhancing overall wellbeing

What Type of Exercise is Best?

A balanced program typically includes:

• Strength training (2–3x per week)

• Low to moderate intensity aerobic exercise (e.g. walking, cycling)

• Mobility and flexibility work

The key is to match the program to your current energy levels and symptoms.

Exercising Safely with Thyroid Disease

Because symptoms can fluctuate, exercise should be:

• Individualised

• Progressive

• Flexible based on how you feel

On lower-energy days, reducing intensity or duration is often more beneficial than skipping movement altogether.
