Exercise in pregnancy

In short

01

Keep moving

About 150 minutes of moderate activity a week is advised if you are well. Walking and swimming are easy places to start.

02

Strength and stretching

Gentle strength work, yoga and pelvic floor exercises are fine for most people. Tell the teacher you are pregnant.

03

What to avoid

Avoid contact sports, activities with a risk of falling, and lying flat on your back for long periods later on.

04

Stop and call if

You feel dizzy, short of breath, have chest pain, bleeding, fluid leaking or less baby movement.

Why moving helps

Regular activity in pregnancy is linked with better mood and sleep, less back pain, and a lower chance of high blood pressure and gestational diabetes.

It can also help you feel stronger for labour and recover faster after the birth.

How much is enough

UK advice is about 150 minutes of moderate activity a week, such as five 30-minute walks, plus some strength work twice a week.

Moderate means you can still talk but not sing. If you were not active before, start with 10 minutes a day and build up slowly.

Good choices

Walking, swimming, aqua natal classes, stationary cycling, pregnancy yoga and Pilates are all good options.

Strength work with light weights or your body weight is fine for most people. Tell any teacher you are pregnant.

What to avoid

Avoid contact sports such as kickboxing, and activities where you could fall, such as horse riding or skiing. Avoid scuba diving.

After about 16 weeks, avoid lying flat on your back for long periods during exercise, as it can make you feel faint.

Your pelvic floor

Pelvic floor exercises help support your bladder and bowel, and can help prevent leaking. Try to do them every day in pregnancy and after birth.

Squeeze and lift as if stopping a wee, hold for a few seconds, then relax. Add quick squeezes too.

Good to know

Can I keep running?

Many people can if they were runners before. Listen to your body and talk to your midwife.

Is exercise bad for the baby?

No. For most healthy pregnancies, regular activity is safe and linked with benefits.

Can I do sit-ups?

Avoid hard ab work like crunches later on. Gentle core work and pelvic floor exercises are better.
