Since losing almost 45 pounds, I've joined a gym and am now trying to increase my cardiovascular fitness. I had a scare last year with a tentative finding of pulmonary hypertension, which has yet not been proved nor ruled out. However, since losing all the weight, I'm no longer having shortness of breath when I exercise.
Anyway, I can't seem to increase my endurance on the elliptical. 20 min is the most I can do, and I'm dying after that. My heart rate gets up to about 140-150, but I'm on meds so it doesn't get much higher (I also had problems with unexplained tachycardia, hence the meds)
I'll go back to the cardiologist eventually, but anyone have any ideas? I go to the gym about 3 times a week, cardio every time, water aerobics once a week, and weight training every time.
Thank you in advance, and good to see everyone. Some of you I know (big surprise, eh?) some I don't.
