Dr. Margie Davenport, PhD: Exercise in Pregnancy, the 140 BPM Myth, and Why Pregnancy Complications Predict Heart Disease
Longevity Optimization with Kayla Barnes-Lentz
Show notes
Pregnancy has long been treated as a season to slow down and play it safe. The data tells a different story, and it starts with a number most women were taught to fear.
Dr. Margie Davenport, PhD, is an exercise physiologist and professor at the University of Alberta who has spent over a decade studying how the body moves through pregnancy, postpartum, and the years before.
What stayed with me most: a pregnancy complication isn't just a pregnancy problem. It's information about a woman's future heart health that most of us are never told to pay attention to.

This conversation explores
Why the “stay under 140 beats per minute” rule taught to pregnant women for decades was already outdated before most of us ever heard it
What Dr. Davenport's lab is learning by tracking a baby's heart rate and blood flow in real time during heavy lifting and high intensity training
Why gestational diabetes, preeclampsia, and gestational hypertension are now considered a risk factor for future heart disease as strong as smoking
Why the “high risk at 35” label given to so many pregnancies is based on outdated data rather than a woman's actual health
Why almost no strength exercise, including deadlifts and heavy squats, has been shown to need to be avoided in a low risk pregnancy
Why the standard advice to wait six weeks and then resume normal activity after birth has little evidence behind it
How staying active after birth is tied to a real reduction in postpartum depression and noticeably better sleep quality, even when total sleep doesn't change
