You are about to reach the finish line! Yes, the third trimester of pregnancy is that period of time when you are closer to welcoming your newborn. The baby continues to grow and mature, you continue to gain weight and all these new changes might make you more uncomfortable.

To prepare well for a smooth delivery, it is good to get started with various activities to stay active. But before we look at how to stay active in the third trimester, let us take a look at the ideal weight gain in the third trimester.

Ideal weight gain during the third trimester

Weight gain during pregnancy is normal. However, the amount of weight gained during pregnancy can determine the immediate and future health outcomes of a woman and her baby.

Population studies have shown that the age at which women become pregnant has changed dramatically over the past decade. In recent years, more women are overweight or obese at conception. Evidence suggests that there are associations between excessive gestational weight gain, increased birth weight, and postpartum weight retention but also between inadequate weight gain and decreased birth weight.

The guidelines on gestational weight gain aim to optimize the outcomes for the woman and the infant. In the year 2009, the Institute of Medicine (IOM) published revised gestational weight gain guidelines that are based on pre-pregnancy body mass index (BMI). These guidelines range from underweight, normal weight, overweight, and obese women and are recommended by the World Health Organization.

These guidelines are independent of age, parity, smoking history, race, and ethnic background. Other changes include the removal of the previous recommendations for special populations and the addition of weight gain guidelines for women with twin gestations.

The IOM recommended gestational weight gain for a twin pregnancy is as follows:

  • For women of normal weight- 16.8–24.5 kg (37–54 lb)
  • For overweight women- 14.1–22.7 kg (31–50 lb)
  • For obese women- 11.3–19.1 kg (25–42 lb)

The IOM guidelines recognize that data are insufficient to determine the number of weight women with multifetal (triplet and higher-order) gestations should gain.

Why is weight monitoring crucial?

During pregnancy, it is essential to discuss the appropriate weight gain, diet, and exercise initially and periodically until delivery. Individualized care and clinical judgment are necessary for the management of the overweight or obese woman who is gaining weight or is trying to gain less weight than recommended.

The weight gain might not always have an effect on the appropriately growing fetus. However, balancing the risks of fetal growth, pregnancy complications, and maternal weight retention is essential. It has been challenging and will remain challenging until research provides evidence to further refine the recommendations for gestational weight gain.

Why is it important to stay active during the third trimester?

Staying active during pregnancy and especially the third trimester ensures that your heart and lungs are healthy, and are well prepared for the tough hour of labor and delivery.

As per the Centers for Disease Control and Prevention (CDC), moderate physical activity like brisk walking is good for the heart and lungs. Physical activity is also instrumental in improving your mood during and after your pregnancy.

After the baby is born, physical activity can aid in maintaining a healthy weight as well as weight loss, if partnered with a low-calorie diet. It is generally advisable for pregnant women to do exercise for 150 minutes, which means 30 minutes per day for five days a week. And this need not be a stretch, you can spread it throughout the week at your convenience.

Some additional benefits of exercise during pregnancy are fewer backaches and constipation, prevention of gestational diabetes, improved posture and muscle tone, etc.

If you are wondering whether this physical activity and exercise is good or bad for you, then science has some good news for you! According to scientific evidence, moderate physical activity like brisk walking bears very low risks to pregnant women.

Unless you are medically unfit to perform any physical activity and have been advised strict bed rest by your doctor, you can safely continue to exercise. Exercise during pregnancy does not put you at the risk of a miscarriage. It is always best to consult your doctor before beginning any form of exercise. Read on to know how to stay active in the third trimester!

Things to do in the third trimester

Pregnant women can perform brisk walking, swimming, low-impact aerobics, yoga, stretching exercises, ball exercises, etc.

Brisk walking

Walking is a good exercise for the third trimester and when coupled with jogging, it improves your mood and cardiovascular health. It is easy on the joints and muscles and provides a total body workout.

Swimming

Swimming and water aerobics are great third trimester exercises for cardiovascular health and are also mild to your joints. The water provides support to your weight and prevents injuries. Swimming raises your heart rate but does not cause overheating.

Squats

Squats help stretch the entire body and prepare you well for delivery. You can try different types of squats.
Here’s how to do sumo squats during pregnancy:

  • Step out into a wide stance with your feet wider than shoulder-width apart and toes pointing outward, make sure your knees are in line with your toes.
  • Slowly lower yourself into a squat. Only go as far as you’re comfortable while keeping your back straight. Keep your weight in your heels, and knees in line with your toes.
  • Keep your legs evenly turned out throughout the movement, don’t let your knees cave in toward each other.
  • Now slowly return to the starting position, squeezing your glutes on your way up.
  • Do 3 sets of 10 to 15 repetitions. Stop in between if you feel uncomfortable.

Stretches

Pregnancy stretches help ease you as the pregnancy progresses; they help relieve backaches and improve posture.
Try out these stretches:

  1. The hamstring stretch
    Stand up straight. Keeping the right foot flat on the ground, bend the right knee slightly and extend the left leg forward. Flex your left foot with your heel firmly on the ground. Hold the stretch for 10 seconds and repeat 2-3 times on each leg.
  2. The hip rotation
    Stand with your feet apart and your hands on your hips. Start rotating your hips slowly in the clockwise direction. Rotate 3-5 times and then rotate in the anticlockwise direction. Feel the stretch in your lower back while doing so.
  3. The knee to chest stretch.
    Lay on your back. Now lift your right leg and slowly draw your knee close to your chest. Hold your right leg close to your chest with your hands and feel the stretch. Repeat on the other side as well.

Ball exercises

Ball exercises can be done in the form of stretching, like a backward stretch with a fitness ball or a pelvic tilt with the ball. These strengthen the back muscles, pelvis, and thighs and improve posture.

Try out ball exercises like:

  1. Ball Squats
    To perform this exercise, hold the ball with your back against a wall. Now perform a squat without dropping the ball. This helps with relieving muscle pain.
  2. Ball bouncing exercise
    To perform this exercise, gently bounce on a birthing ball for a few minutes at a time. This exercise can improve stability and balance and strengthen your legs.
  3. V sit
    Lie down on the floor on your back and your legs elevated such that your ankles are resting on top of the birthing ball. Slowly raise your upper body until you form a V-shape. Keep your hips on the floor. Hold this position for 5 counts and then slowly lower your upper body to the floor. Do not perform if you feel any discomfort while exercising.
