I've used a bowflex for about four years. I've run into an interesting (read: frustrating) phenomenon the last two winters. I don't heat my home during the day, so when I return home after work to exercise the house is cold. I've noticed during these times that my weight lifting ability declines dramatically.

I can understand that one who is chilled (which I am during these sessions) might not possess the same muscular strength that one has when warm and comfortable, but the difference is so great that I have to think that something else is going on.

I'm wondering if the bowflex power rods demonstrate varying stiffness depending on ambient temperature. That is, they stiffen when cold and offer more resistance to bending. Thus a 50 lb power rod might provide 50 lbs of resistance at 80 degrees and, say, 60 lbs at 60 degrees.

Has anyone experienced the same situation and, if so, can you offer an explanation?

I appreciate any advice that can be offered.
