Several years ago, I did nothing but Leslie for 9 months - at least 4X a week while holding 1-pound hand weights. Then one night I was feeling weird, my left arm hurt and my chest was feeling tight. I freaked, went to the hospital and it turned out to be nothing BUT ...
During the stress echocardiagram where you fast-walk on a treadmill until you’re literally ready to drop and they monitor your heartrate and recovery, they took me off the treadmill early saying it was pointless to go further because my cardio capacity had already proven to be very high. The doc said it was obvious that I worked out a lot. A lot? I walked 4 times a week. How hard is that?
