**Comment:**
“As a runner who continued training through pregnancy, I learned the hard way how crucial proper **maternity sports bras** are. Around my second trimester, my usual high-impact bra became unbearably tight, yet switching to a looser one caused chafing during long runs. I wish Iβd known sooner about adaptive smart fabrics like the article mentions! Finally, I invested in a **maternity**-specific design with adjustable straps and breathable meshβgame changer. It accommodated my changing size without sacrificing support, even postpartum during breastfeeding. For active moms, the right bra isnβt just comfort; itβs the difference between staying mobile or sidelined by pain. This piece nails why βmaking doβ with old bras is a mistake.”
