Before exercising, it's important that you do a five- or 10-minute cardio warmup to get blood flowing to your muscles and help prepare them for prolonged exertion. When it's cold outside, it can be even more difficult to warm up your muscles prior to exercising. Here are five warmup ideas that can be done indoors and with relatively little space. Wear a sweatshirt and an extra layer of sweatpants for additional insulation when completing these exercises.

Mountain climbers:
