Safety

At times, you will not feel like exercising. This is true for everyone. If you're just feeling a little tired or low on energy, go ahead and try to complete your routine. The workout will likely boost your energy level and your mood. However, if you're not feeling well—if you think you might be getting sick, coming down with a cold or the flu; or if you have any kind of pain or swelling—take a break from exercising and, if necessary, contact your doctor. Your health and safety are top priority.

The reasons listed below are good cause to take a day off from strength training. Be cautious. If you're not sure whether you're well enough to exercise, take a break and see how you feel the next day.

Refrain from exercising or check with your doctor first if you:

  • have a cold, flu, or infection accompanied by fever
  • have significantly more fatigue than usual
  • have a swollen or painful muscle or joint
  • have any new or undiagnosed symptom
  • have chest pain, or irregular, rapid, or fluttery heartbeat
  • have shortness of breath
  • have a hernia, with symptoms
  • have been advised by your doctor not to exert yourself for a given period of time due to illness, surgery, etc.

Listen to your body. As you get used to your exercise program, you will know when you're well enough to handle a workout and when you need to take a day off or see your doctor.
