Staying Active in Pregnancy

The idea that pregnancy requires rest and caution used to dominate how people thought about activity during this period. The evidence now points the other way: regular movement during a straightforward pregnancy is associated with better outcomes for both the pregnant person and the baby, including reduced risk of gestational diabetes, better mood, lower rates of excessive weight gain, and easier labour. The goal isn't performance or fitness maintenance; it's keeping the body moving in ways that feel manageable and good.

Most people can continue the movement they were already doing when they became pregnant, with adjustments as the pregnancy progresses. Those who weren't active before pregnancy can start gently and build up. The key principle is that pregnancy is not the time to begin high-intensity training from scratch, but it's also not the time to stop moving.

What's generally considered safe

Walking is the most universally appropriate form of exercise throughout pregnancy and requires no adaptation until very late in the third trimester. Swimming is excellent for most of pregnancy because the water supports the growing bump and reduces joint strain. Yoga and Pilates, particularly versions designed for pregnancy, are widely recommended for their combination of gentle strengthening, flexibility, and breath work. Cycling on a stationary bike removes the balance concerns that outdoor cycling raises in later pregnancy.

Strength training at moderate intensity is safe for most people in pregnancy, with adaptations. Lying flat on the back is generally advised against from around 28 weeks, as the weight of the uterus can compress the main blood vessels. Free weights and resistance machines can usually continue with reduced load and adjusted positions. If you have a personal trainer, letting them know about the pregnancy enables them to adapt sessions appropriately.

"Pregnancy changes what movement looks like, but it doesn't change the fact that it's important. Moving regularly, in ways that feel good, is one of the better things you can do for yourself."

Pelvic floor work

The pelvic floor is under increasing pressure throughout pregnancy and childbirth. Regular pelvic floor exercises, sometimes called Kegels, are recommended throughout pregnancy and beyond. The NHS guidance is to do them daily, and many people find integrating them into routine moments (waiting for the kettle to boil, sitting at a desk) is the most practical approach.

Seeing a women's health physiotherapist during pregnancy for pelvic floor assessment and guidance is something many practitioners recommend, particularly for those with any current pelvic symptoms or a history of pelvic floor issues. It's much easier to address these during pregnancy than to wait for issues to develop postnatally.

What to be cautious about

Contact sports and activities with significant risk of falls or abdominal impact are generally best avoided from early pregnancy. High-altitude exercise brings its own risks. Hot yoga and other activities that significantly raise core body temperature are advised against, particularly in the first trimester. Any exercise that causes pain, dizziness, chest tightness, or significant breathlessness should be stopped and assessed.

If there is any medical complication with the pregnancy, placenta praevia, pre-eclampsia, or a history of preterm labour, activity recommendations may be different and should be discussed with your midwife or obstetrician.

Movement in pregnancy looks different to movement outside of it, but its value doesn't diminish. Keeping going, in whatever form works for your body and your stage, is worth the effort.
