Cold floors during a winter work out

Working out in the winter is way harder. It is no wonder that we all put on winter weight. I don’t want to drive to the gym in feet of snow and ice on the roads. Most of the time I end of working out in my home. It is always a really pitiful workout. Getting warm when your house is around 60 degrees is rough. I usually have to stand right in front of my heating system when I begin the work out. As I get warmer, I then can venture further away from the heater. The issue is not really the air around me being cold though. The problem is that the floors in my home are so cold. Unless I am right in front of the fireplace, I am freezing cold. Doing any sort of jumps, skips or push ups is terrible. The flooring is so cold that my feet usually end up going numb. When I do crunches, it is not easy. Do I want to sweat to death and possibly burn myself on the heater? Or do I want to freeze the entire time on the cold floor? I know heated flooring would really be the best possible heater in this situation. The bigger problem is the lack of insulation around my baseboards though. The house lets in the cold air through the windows and under the doors as well. The cold air then is at my flooring level, ruining my workout. Rather than get a better heater device, I need to seal up the home properly. If the home stays cold, my workouts will continue to suffer.
