Exercise During Pregnancy: What Is Safe and What to Avoid

How much exercise is recommended in pregnancy, the safest activities, what to avoid, and warning signs to stop.

For most people, staying active in pregnancy is safe and good for both you and your baby. It can help with back pain, sleep, mood and a healthy weight gain, and may lower the chance of gestational diabetes.

How much exercise?

ACOG recommends at least 150 minutes of moderate activity a week, such as 30 minutes on 5 days. Moderate means you can still talk, but not sing. If you were active before pregnancy, you can usually continue with some changes. If you were not, start slowly.

Good choices

  • Walking
  • Swimming and water aerobics
  • Stationary cycling
  • Low-impact aerobics
  • Pregnancy yoga and Pilates
  • Light strength training with good form

What to avoid

  • Contact sports and activities with a high risk of falls, such as horse riding, skiing or gymnastics
  • Scuba diving
  • Hot yoga or exercising in very hot conditions
  • Lying flat on your back for long periods after the first trimester
  • Exercising at high altitude if you are not used to it

Stop and get advice if you have

  • Bleeding from the vagina or fluid leaking
  • Chest pain, dizziness or feeling faint
  • Shortness of breath before you start exercising
  • Regular painful contractions
  • Pain or swelling in your calf
  • Headache or muscle weakness

Some conditions, such as certain heart or lung problems, placenta previa after 26 weeks or a risk of preterm labour, mean exercise should be limited. Always check with your doctor or midwife.
