Can I continue running during pregnancy if I was a runner before?

If you were running before pregnancy and your OB has cleared you, you can continue — just modify as your body changes. Key guidelines: slow your pace (you should be able to hold a conversation), switch to softer surfaces like tracks or grass as your joints loosen from relaxin hormone, invest in a good supportive sports bra, stay very hydrated, and listen to your body. Most runners naturally shift to jogging then walking by 28–32 weeks as the belly grows. Stop if you feel pain, dizziness, shortness of breath, or pelvic pressure.
