Hello, So many great answers to your post!! I wonder the same thing about exercising from time to time, whether it's ok or not ok or what might be the consequences ? I'm with your doctor. Live your life and be as strong and fit as you can be. Just be mindful of your body during your workouts and listen to its signals. It will let you know if you need to slow down and take a breather. And you should be tired or sore after lifting a bit of weight. Because you are not used to it and your muscles are reacting to being used. It's not necessarily a bad thing unless you are really overdoing it. Actually, I've read recently that "they" are considering adding moderate exercise as a potential treatment for HCM as it does strengthen your muscles, including your heart, it helps with your body's use of oxygen and circulation, helps to maintain a healthy weight, it's great for your mental outlook, it does so many positive things for your mind and body. Versus the alternative... sitting around listening to your heart beat and worrying about what might happen... I workout 5-6 times a week for 45-90 minutes - weights that are a decent weight for me and 3 sets 10-15 reps I try to hit all major body parts. My cardio is mostly rowing as that works all body parts and I can easily control my level of heart rate etc. Working out is more like meditation to me and I do have to pause now and then to let things in my body settle. And I have an ICD so feel I'm covered if anything really bad happens. Just have to live each moment and do what you love to do and what feels best for your mind/body. I think that will go a long way in making it easier to live with this condition that we share.
