I was in the gym today and a (bro-science) trainer told me that I shouldn't use the stair climbing machine because it causes abnormal heart enlargement and associated heart diseases. I asked him for a resource and he said he saw is on Facebook but other trainers vouched for that and said they had heard it too.
I couldn't find any resource for this. The only thing I could find is Heart.org saying:
Most physicians will advise caution to a patient with an enlarged aorta (the major artery in the body). (An enlarged aorta can occur in people with Marfan syndrome, Turner syndrome, coarctation of the aorta, or a bicuspid aortic valve.) There is no proven link between exercise and harmful outcome from an enlarged aorta
Is there absolutely any link between stair climbing and heart disease?
