Warming up gradually revs up your cardiovascular system, increases blood flow to your muscles and raises your body temperature. Choose a warm-up activity that uses the same muscles you'll use during your workout. If you're going to run, walk briskly for five to 10 minutes. A warm-up may cause mild sweating, but it shouldn't leave you fatigued.
