Very Low Risk
Moderate exercise is healthy and perfectly compatible with breastfeeding, with no changes in the composition of milk or a decrease in its production, which may even increase (Be'er 2020, CML 2012, HWA 2009).
Maternal exercise does not cause weight loss in the infant (Daley 2012, Su 2007, Dewey 1994).
Resistance and aerobic exercise can delay bone loss during breastfeeding (Lovelady 2009).
Intense exercise might decrease the concentration of IgA and lactose and increase the concentration of lactic acid and protein, with possible taste change, but this is well tolerated by the infant (Wright 2002, Quinn 1999, Carey 1997).
Continuous intense exercise would only be advisable in women who have previously been involved in fitness training, eg: professional athletes.
