Does Exercise Affect Milk Supply?

September 15, 2019

Our goal at FPC is to get you regaining strength and making a postpartum recovery as soon as possible.  We all know the physical demands of mom life start right away.  That means coming to Rehab as soon as you can get out the door and coming into Postpartum Signature as soon as your care provider gives you clearance.  But there is a very persistant myth that “working out” may affect milk supply.  We’re here to set the record straight!


We asked Erin Williams, doula, childbirth educator, pre/postnatal corrective exercise specialist and certified lactation counselor of Doulight NYC ,

Is there any truth to the myth that working out will affect your milk supply?

Many nursing parents wonder if they can still workout without tanking their supply. Their common concern is hydration and that sweating will lead to a dip in milk supply. You absolutely can workout while nursing! Just be mindful of staying hydrated (as you should just living your normal non nursing life as well!). Milk supply is based on demand so as long as you are stimulating your body to produce milk (nursing, pumping or hand expressing) your supply should remain. If you’re missing a feed to work out just be sure to pump to remind your body that you still need to make that milk! 

From a fitness standpoint, exercise makes for a much happier mother which in turn means a happier baby.

Here are a few of the benefits of getting back to moderate movement at FPC as soon as you are able!

  • Increased blood flow
  • Improved energy
  • Reduced stress levels
  • Improved feeling of well being
  • Higher level of strength and cardiovascular endurance
  • Alleviation of depression symptoms
  • Creating friendships and connection to other mothers!


Have you been worried about your supply and returning to exercise?  Has anyone given you a hard time about working out while pumping or nursing?
