There needs to be more clarity about exercise for HCM patients. Some doctors say, "don't do anything physical," and others say, "do whatever you want." We can likely agree on one thing – the best advice is somewhere in the middle.

Experts agree that exercise is healthy for people with HCM. Depending on symptoms, most people with HCM can safely do at least light exercise. 

Those with HCM who have no symptoms may be able to exercise without restrictions.

• Most people with symptomatic HCM aren't advised to do heavy exercise. They should avoid intense activity with bursts of sprinting, heavy weightlifting, or contact sports like football. 
• Research indicates that intense physical activity predisposes susceptible people with HCM to arrhythmias and possibly sudden death.
• The LIVE-HCM studyresults found that vigorous exercise did not raise the risk of dangerous arrhythmia, appropriate ICD shock, or sudden cardiac arrest for most people in the study.

More research into this topic is ongoing, so we will know more soon.

Fast Facts About Exercising When You Have HCM:

Most HCM patients should exercise.

• Walking, bicycling, lap swimming, and other gentle activities are generally safe forms of exercise. If swimming, be sure there is a lifeguard or have a buddy.
• Those with symptoms should not overexert themselves.
• Listen to your body and slow down or stop if your symptoms increase. 
• When exercising, avoid extreme temperatures and stay hydrated.
• HCM patients don't do well with very hot or very cold conditions.

If you want to join a gym, be familiar with the safety laws in your state.

• Are gyms required to have automated external defibrillators (AEDs)?
• Do employees need CPR certification?
• Work with your HCM specialist to find the best activity level for you. 
• What's safe? Your doctor may use a stress echo or CPET/VO2Max to find out how you react to exercise. This will help you understand your limits.
