Also, there are more people on this site alone that have been studying for more than three months and still haven't cracked 160 than there are people who went from sub 140 to over 170 in less time.
I brought a thermal sweater with me since I was told this building is usually super cold. Maybe it was, but with a resting HR of 140, I was fine with a t-shirt and sweat pants. I always make sure to remember to bring pants. -Mike
