Exercise in Pregnancy

Cardiorespiratory Exercise:
Moderate intensity cardiorespiratory exercise should be performed for 150-300 minutes/week OR Vigorous intensity exercise should be performed for 75-150 minutes/week.​

What classifies as moderate intensity exercise?  A few different scoring systems exist to gauge exercise intensity but I like the Talk Test the most.  The talk test is simple and well-proven.  If you can only say 2-3 words while exercising you are participating in moderate intensity exercise.  If you can utter 2 words or less, you are participating in vigorous intensity exercise. 

*Vigorous activity is okay to continue if it was done regularly before pregnancy occurred.  If it was not performed before pregnancy you should speak with your physician.

*Pregnancy progress should be monitored by a healthcare provider at a regular interval.

*If you are not currently exercising and wish to begin an exercise program you should consult with your physician to discuss your readiness and the need for additional screening.
