hello, i dont know if im the only one here but since my panic attack and anxiety which followed, i have noticed that my aerobic exercise capacity has decreased, i go to the gym about 3 tiimes a week and have no problem doing strength training, which has actually improved, however when it comes to running on the treadmill, i used to run about 5km over 20 minutes, but am now struggling and stop after 3.5 - 4km, with my chest and upper back becoming very tight and my breathing going a lot quicker than compared to before, i also feel more panicky and turn the machine off around this distance, as already mentioned this wont happen with weightlifting, is it possible that my anxiety is really impacting on my aerobic exercise capacity?
