Know what your body can do when limited by a thyroid condition.

While there’s no doubt exercise plays a role in a healthy lifestyle, it is even more important to tune into what your body can do when medical reasons may limit you.


My mentality towards exercise has shifted over the last two years. I’ve learned for my body, less is more.

So how did I go from being an active person to deciding not to step foot in a gym again?

Let’s back up and chat about how it all started. My active lifestyle started all the way back when I was a kid. Between recreational soccer and joining the cross-country team, I had an active childhood. As I grew up, I stayed an avid runner, soccer player, and had several gym memberships into my early twenties. I loved the mood-boosting effects of being active, and can still recall what it feels like to have “runner’s high.” Even when a heavy work and school load disrupted my typically active routine, I tried to keep up with fitting in workouts.

Then I was diagnosed with Hashimoto’s disease, an autoimmune condition that impacts the thyroid. I tried to keep the same approach, even though I was symptomatic at the time: cold hands and feet, muscle aches, foggy head, and fatigue plagued me. I struggled with any activity, yet forced myself to say active. I started on medication and was managing my symptoms as well as I could, but I began to notice exercise was a struggle.

I didn’t enjoy it anymore.

There were bouts of fatigue, muscle aches, and headaches, yet I continued to push myself at the gym with weight lifting and high intensity interval training. It felt like weights were attached to my legs as I trudged along for a half-hearted run.  What I didn’t realize at the time was I was hurting my body more than helping it.

So why do individuals with Hashimoto’s experience muscle weakness, exercise intolerance, cramps and fatigue?

It comes down to energy production. Hypothyroidism induces metabolic myopathy, a condition of abnormal muscle energy metabolism. The body lacks its essential metabolic driver (thyroid hormone), so it can’t produce sufficient energy for regular metabolism, let alone exercise. The result is:

  • Constant fatigue
  • Muscle aches and cramps
  • Muscle weakness or decreased strength
  • Weakened immune system
  • Poor recovery

While exercise with Hashimoto’s has many benefits, but it’s the duration (how long) and type that may or may not be beneficial.

I became accustomed to feeling tired and always in desperate need of a nap. I couldn’t figure out an exercise routine that worked for me, and slowly realized that what worked for me in the past no longer felt good. Even as an active person, exercising was no longer good for my mental health.

I knew my body needed something else. It was time for a change, so I quit the gym and joined a yoga studio instead.

Those who experience exercise intolerance and low exercise recovery can consider modifying their exercise routine by:

  • Approaching exercise mindfully, and incorporating mindful movement that feels good such as yoga, walking, hiking and tai chi.
  • Limiting high intensity workouts, excessive cardio, and long duration exercise.
  • Taking a nap when you need a nap. Rest and recovery is crucial to manage Hashimoto’s.

The idea of “less is more” when it came to exercise was scary at first. I played competitive sports for a long time and wondered if yoga would be “enough” of a workout.

The first thing I noticed? I didn’t feel like crap after class.

After a few months practicing, I felt a little calmer, less achy, and less stressed. Yoga has become my mainstay not only for physical, but mental health. Slowly but surely, I could see and feel the changes in my body.

Yoga taught me to tune into my body and be more mindful.

I started to notice when I was able to push myself more, and when to back off and rest instead. Regular yoga practice improved my balance, flexibility and strength without fear of overdoing it or suffering from an autoimmune flare-up. In fact, science and research suggests yoga practice can reduce the impact of exaggerated stress responses often found in autoimmune conditions.  Emotional benefits were experienced through yoga by relieving stress and anxiety, building my confidence, and teaching me what it means stay in the present.

Now I approach physical activity with more joy. Strenuous gym workouts have been replaced by an activity that makes me feel good,

And made me love to move my body again.
