The other day I went to get a cardio stress test at the doctor's office. The nurse looked at me and figured since I look muscular that I'd be able to do at least 14 minutes on the treadmill with 3 minute intervals of increase in incline and speed. I told her, I'm not so sure... Ended up maxing out at 10:30. I was so winded it was crazy. I even had some PVC's in there. This was rated as "below average" for my age.
This really got me thinking. I should do more cardio. I have never really done cardio before and I always got winded faster than my friends (but I was always stronger and bigger than my friends). This sucks. I'm concerned because my cardio is so bad I get winded doing anything really.
How many of you do cardio and how has it affected your quality of life as opposed to just lifting? I'd like to start doing more cardio for health reasons. I suffer from high blood pressure and have been having arrythmias and palpitations in the past few months. I'd just like to get my heart healthy.
