Welcome to your last trimester, where your tummy is growing larger and your baby gets heavier by the week. Hormonal changes have also increased the likelihood of water retention, so you may notice your arms and legs swell. You're feeling tired and breathless and no one will blame you if all you want to do is lie down and watch TV. However, despite experiencing fatigue more easily, you're encouraged to continue exercising — especially if you've done so throughout your pregnancy so far. Here's why!

I'm so tired. Why should I still exercise?

third trimester why exercise

Exercise helps you to prepare to meet the physical demands of labour and birth. A good workout can be energising yet relaxing! It also reduces the chance of constipation and helps you better manage your weight. Exercise also helps control your blood glucose levels and blood pressure. Just to be safe, please seek medical advice from your obstetrician before starting any new exercise programme.

OK, I'll get off the couch. So what exercises should I be doing?

Generally, if you have not been exercising regularly before pregnancy, start with an easy 15 minutes of activity a day. Gradually increase that to 30 minutes a day, five to seven days a week. These exercises can include walking or stair climbing — just be aware that your new body will require some balancing.

Pelvic floor exercises are a great way to maintain the strength of pelvic floor muscles to prevent stress urinary incontinence and in future, organ prolapse. Here's how you do it: Imagine that you're trying to stop yourself from passing wind and trying to stop your flow of urine mid-stream at the same time. The feeling is one of "squeeze and lift", closing and drawing up the front and back passages. Hold this position for a few seconds, then release. Do at least eight contractions three times a day.

Hormonal and postural changes may cause you to develop back pain during this trimester. Back exercises like pelvic tilts can help to alleviate these discomforts, as well as those mentioned above.
