No pain, no gain? No way!

By Mayo Clinic Staff

When it comes to exercise, the "No pain, no gain" mantra is bad advice. Exercise shouldn't hurt. At most, you may feel a little muscle soreness when you do a new workout or activity. If you feel pain during exercise (or dizziness, nausea or shortness of breath), stop. You may be pushing yourself too hard.
