Does anyone else really struggle with exercise? I seem to get so out of breath so easily. If I attempt to run on a treadmill I have to stop after 5 minutes as I am so short of breath! It has been this way since I was younger, just wondered If anyone else experiences the same. Granted I do not work out regularly but I seem to get short of breath walking up a flight of stairs (not gasping or anything of the sort but a little breathless for a sec or two!). Anyone else? Or just me and do I need checking out? I am not overweight.
i get that out of breath you need to check your blood pressure if its high ?
It’s not high, never has been and I have had it checked so many times
Im skinny, look like Im in shape but I have the endurance of an overweight person. Stairs wind me. lol. I have IST which is a very fast heart rate and I think contributes to this.
I have the same issue, I have been getting more regular exercise but only when I am with my friend. I found at the start I couldn’t run for a minute without getting really out of breath, but it is steadily getting better. I think if you stick out exercise you will get less tired slowly over time.
I have always been told to run as fast as you can, but not fast to the point where you wouldn’t be able to hold a conversation with someone. I do a very slow and leisurely jog to attain this.
Wish you the best
