Welcome to FitDay! Similar situation? No. 80's and 90's shouldn't confine you to your home. I live in southeast Louisiana and if I let 80's & 90's hold me back, I'd hardly ever leave. A couple days ago I did a half marathon (in Va Beach) and I was ecstatic to see that it was only in the low 80's.
IMO I would never try to execise while watching TV. Maybe if you have a treadmill in front of the TV but most people relax (sit or lay down) when watching TV. I wouldn't expect any workout to be very productive during that time. I think a workout should be important enough to get someones undecided attention. Maybe that's just me though.
