Do you need to warm up before you exercise?

By Mayo Clinic Staff

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.
