You may be able to continue using OSX while breastfeeding, but your training and nutrition may need to be adjusted based on your recovery and individual needs.

OSX is built around structured training, real-food nutrition, and consistency. If you recently gave birth or are breastfeeding, speak with your doctor, midwife, or another qualified healthcare professional before returning to training or making significant changes to your nutrition.

OSX is also continuing to expand its training options for women across different stages of life.

The core OSX nutrition approach can still be used while breastfeeding.

Focus on:

Breastfeeding can increase your energy and nutritional needs, so your normal calorie target may need to be adjusted.

Rather than aggressively reducing calories, use the OSX nutrition structure as your foundation and make sure you are eating enough to support your recovery, training, and breastfeeding.

If you are unsure how much you should be eating, speak with your doctor, midwife, or another qualified healthcare professional.

If you have been cleared to exercise, choose training that matches where you are in your recovery.

OSX includes different styles of training, from resistance workouts to Pilates and lower-impact options, so you can choose something that feels appropriate for your current level.

Start gradually and focus on:

If something does not feel right, stop and speak with your healthcare provider.

OSX provides general fitness and nutrition guidance and should not replace medical care.

Always consult your doctor, midwife, or lactation consultant before changing your diet or exercise routine while breastfeeding, particularly if you recently gave birth, had a C-section or other complications, are recovering from an injury, take medication, or have concerns about your milk supply or recovery.
