4 million women give birth each year in the US with no uniform course of physical therapy to mitigate weakness or injury caused by pregnancy and delivery.

More than 50% of women report back pain during or after pregnancy and 60% suffer from diastasis recti (split abdomen)

Your baby. Your body. You got this.

When you’re trying to learn about what happens to your body pre- and postpartum, or what physical activity is considered safe for you and baby, there’s a lot of conflicting information. Not being confident in your choices can cause anxiety.

No matter where you are in your postpartum journey, we invite you to participate in our market research to help us shape a program aimed at helping women recover, rebuild muscle strength, and improve stability. For this digital focus group, we are looking for women who recently had a baby and whose primary form of exercise is running.

“I have witnessed firsthand the adverse effects of returning to exercise and everyday activities without proper recovery from pregnancy and delivery. core2u combines the knowledge of multiple medical experts to educate women about the safest ways to remain active and return to exercise while adapting to the changes that occur during and after pregnancy.”

Joy and Pain: A Mother’s Story

“Hi, I’m Michele and I have three wonderful sons. My motherhood journey has been one of immense joy, yet unexpected pain.”

  • An energetic mother of three, Michele has been active all her life: road races, bike-a-thons, hiking, to name just a few of her passions.

    She was in great physical shape going into her first pregnancy, but she received little or no direction on what she could do safely during and after pregnancy.

    After the birth of each of her children, she followed the recommended six weeks of rest and then resume her fitness routine. But with each pregnancy came months of crippling back pain that left her immobile for days at a time, missing out on time with her children and many days at work.

    Michele’s seven years of recurring pain prompted her to search for answers on her own, spending time and money on acupuncture, chiropractic care, physical therapy, massage and pain medication.

    Finally, she found a physiatrist at Massachusetts General Hospital who put the pieces of the puzzle together. She identified that Michele’s three pregnancies wreaked havoc on her abdomen and that by not repairing those muscles and resuming her normal activities without easing her way back, she left herself open to injury.
