How to do it

  1. Notice when the pain started: during the lift, or the next day.
  2. Notice what kind it is: a dull ache across the muscle, or sharp pain in one spot or a joint.
  3. Look for swelling, bruising, a visible change in shape, weakness or a limp.
  4. Treat plain soreness with easy movement such as walking, and let it fade over two or three days.
  5. Skip hard training on a body part that is still very sore.
  6. Stop the exercise at once if you feel a pop, a sharp pain or a joint giving way.
  7. Call your local emergency number, 911 in the US, for chest pain, pressure or fainting during exercise.

Stop and call a professional if

  • You feel chest pain, pressure, fainting or severe breathlessness during or after exercise: call your local emergency number, 911 in the US.
  • Your urine turns dark brown or cola colored with severe muscle pain and swelling after a hard session: go to an emergency room now or call your local emergency number, 911 in the US.
  • Pain is sharp, in a joint or bone, comes with swelling, a pop or weakness, or has not eased after a week: see a clinician.

Common mistakes

  • Training through sharp pain because you think soreness is a sign of progress.
  • Mistaking chest pain for a pulled muscle.
  • Ignoring very dark urine and severe muscle pain after an extreme session.
