Well, I know, "heat is the enemy", and that makes for tough times, when trying to exercise during the Summer.
I have my temperature (regulated via air conditioner) around 79 degrees, and it feels comfortable, to my wife.
I, myself, always feel like I'm freezing, no matter how warm it gets. Heck, I sleep with a sheet and two blankets over me, at night (sometimes I even turn the heat, all the way up, on my heated mattress pad).
Anyways, back to exercise, I use my exercise bike, I do a "warm-up" mile (in about 4 minutes), then a 20 mile "main exercise" (in about 1 hour or 60 minutes), then I finish with a "cool-down" mile (in about 4 minutes). I have noticed that my blood pressure actually drops, during exercise, the other night to 98 over 52. My pulse rate, after the "main exercise" is around 120, and after "cool-down" is around 106. (Yes, I actually stop and take my blood pressure and pulse).
When any of you exercise, does your blood pressure drop also?
