What to Avoid or Adjust While Breastfeeding

Extremely High-Intensity or Prolonged Workouts

While occasional moderate exercise is acceptable, intense workouts without sufficient hydration or nutrition may temporarily elevate lactate levels in breast milk (which is generally harmless but can alter taste). If this happens, feeding before exercising or taking a brief break afterward can be beneficial. Mayo Clinic
