Yes, many women can continue or begin appropriately modified prenatal yoga during the second trimester if their pregnancy is uncomplicated. Gentle yoga may support flexibility, relaxation and physical activity during pregnancy. However, poses, intensity and duration should be adapted as the body changes, and women with pregnancy complications should follow advice from their healthcare provider.
What Are the Benefits of Yoga in the Second Trimester?
Prenatal yoga is not a treatment for pregnancy complications, but gentle yoga may support general physical and emotional wellbeing.
1. Helps you stay physically active
Staying active during pregnancy can help support overall health. WHO recommends regular physical activity throughout pregnancy for women without contraindications and recommends at least 150 minutes of moderate-intensity aerobic physical activity across the week.
Yoga can be one component of an active lifestyle, although it should not automatically be counted as equivalent to 150 minutes of moderate-intensity aerobic activity.
2. Supports flexibility and gentle movement
As your body changes, gentle stretching and controlled movements can help you maintain comfortable movement.
The goal is not to stretch as deeply as possible. During pregnancy, move within a comfortable range and avoid forcing your joints or muscles.
3. Encourages relaxation
Prenatal yoga commonly combines gentle movement with breathing and relaxation techniques. The NHS specifically describes prenatal yoga as an activity that can help with relaxation and easing body tension.
4. May support comfort as your body changes
Pregnancy can bring changes in posture and physical comfort. Gentle movement and appropriate strengthening exercises can form part of staying comfortable and active during pregnancy.
If you have persistent or severe pain, however, do not use yoga as a substitute for medical assessment.
5. Builds body awareness
Pregnancy yoga encourages you to notice your breathing, posture, balance and physical comfort.
This can help you become more aware of when a movement feels comfortable and when you need to slow down or stop.
6. Creates time for mindful pregnancy
A slow yoga session can also provide a quiet period to focus on breathing, relaxation and your changing body.
This is a wellbeing benefit—not evidence that yoga directly improves your baby's intelligence, brain development or personality.
What Are Some Gentle Yoga Poses for the Second Trimester?
There is no universal list of yoga poses that is guaranteed to be safe for every pregnant woman. A pose that feels comfortable for one person may not be appropriate for another.
The following movements can be discussed with a qualified prenatal yoga instructor and adapted to your pregnancy:
1. Cat-Cow Movement
A gentle hands-and-knees movement can encourage comfortable spinal mobility.
Keep the movement slow and avoid forcing your back into an extreme range.
2. Standing Side Stretch
A gentle standing side stretch can encourage movement through the sides of the body.
Keep both feet stable and avoid stretching so far that you lose your balance.
3. Supported Butterfly Position
A supported seated butterfly position may provide gentle movement around the hips and inner thighs.
Use cushions or other support if needed and avoid forcing the knees toward the floor.
4. Gentle Pelvic Tilts
Pelvic tilts can be performed with appropriate modifications depending on your comfort and stage of pregnancy.
If a particular position requires you to lie flat on your back for an extended period, choose an alternative or ask a prenatal exercise professional for a modification.
5. Supported Squat
A supported squat may be appropriate for some pregnant women, particularly when performed with stable support.
Your balance and comfort can change during pregnancy, so use a wall, sturdy support or another appropriate modification if needed.
Remember: The aim is gentle movement, not achieving a particular pose.
Which Yoga Poses Should You Avoid or Modify During the Second Trimester?
Some yoga movements may need to be modified as pregnancy progresses.
Avoid prolonged lying flat on your back
The NHS advises avoiding exercises that involve lying flat on your back for long periods, particularly after 16 weeks, because the weight of the pregnancy can affect blood flow and may make you feel faint or dizzy.
Be cautious with balance poses
Your centre of gravity changes during pregnancy. Poses that create a significant risk of falling may therefore need to be avoided or modified.
Use stable support when appropriate and choose controlled movements over challenging balance work.
Avoid deep or uncomfortable twists
Do not force your torso into deep twists or any position that creates abdominal pressure or discomfort.
A qualified prenatal yoga instructor can show you pregnancy-appropriate modifications.
Avoid overheating
Pregnancy exercise should not leave you excessively overheated or exhausted. NHS guidance recommends avoiding strenuous exercise in hot weather and staying well hydrated.
Do not push through pain
Stretching can feel different during pregnancy. Pain, dizziness or significant discomfort is a reason to stop rather than push through the movement.
How Long Should You Do Yoga During the Second Trimester?
There is no single yoga duration that is right for every pregnant woman.
If you are already active, you may be able to continue a modified routine that feels comfortable. If you were not exercising before pregnancy, it is generally better to start gradually rather than suddenly doing strenuous workouts.
The NHS suggests that women who are new to exercise can begin with short periods of activity and gradually build up. It also recommends using your ability to hold a conversation as a simple guide to exercise intensity.
WHO recommends at least 150 minutes of moderate-intensity aerobic physical activity spread throughout the week for pregnant women without contraindications. This is an overall physical-activity recommendation, not a recommendation to do 150 minutes of yoga specifically.
You can combine different forms of activity such as:
Walking
Swimming
Prenatal yoga
Pregnancy-appropriate strengthening exercises
Other activities recommended by your healthcare provider
Can You Start Yoga in the Second Trimester If You Are a Beginner?
Yes, some women can begin gentle pregnancy-appropriate exercise during the second trimester, even if they were not previously active.
However, starting pregnancy yoga does not mean starting an intense yoga routine.
Begin gradually, choose pregnancy-specific instruction, and tell the instructor how many weeks pregnant you are.
If you have a medical condition, pregnancy complication or concerns about exercise, speak with your doctor or maternity care provider first.
What Should You Keep in Mind During Pregnancy Yoga?
Before and during your session:
Warm up gently.
Keep water nearby and stay hydrated.
Wear comfortable clothing.
Avoid exercising in excessive heat.
Choose stable positions when balance is affected.
Modify poses as your belly grows.
Do not force stretches.
Stop if you feel pain, dizziness or unwell.
Tell your instructor that you are pregnant and how many weeks pregnant you are.
The NHS also recommends making sure an exercise instructor is appropriately qualified and knows that you are pregnant.
When Should You Stop Yoga During Pregnancy?
Stop exercising and seek medical advice if you develop concerning symptoms during or after exercise.
These may include:
Vaginal bleeding
Fluid leakage
Significant or persistent pain
Dizziness or fainting
Severe shortness of breath
Regular painful contractions
Any symptom that concerns you or feels unusual
If you are unsure whether a symptom is related to exercise or pregnancy, contact your doctor or maternity care provider rather than continuing the workout.
Who Should Talk to a Doctor Before Doing Prenatal Yoga?
You should discuss exercise with your healthcare provider if you:
Have a high-risk or complicated pregnancy
Have been advised to restrict physical activity
Have a medical condition that affects exercise
Experience pain or unusual symptoms
Have concerns about your ability to exercise safely
Are unsure whether a specific yoga pose is appropriate
Your healthcare provider can help you understand what level and type of physical activity is appropriate for your individual pregnancy.
Frequently Asked Questions About Yoga in the Second Trimester
Can I do yoga at 20 weeks pregnant?
Many women with uncomplicated pregnancies can continue or begin appropriately modified prenatal yoga around 20 weeks. However, the routine should be adapted to your changing body, and you should follow your healthcare provider's advice if you have any pregnancy concerns.
Is yoga safe at 16 weeks pregnant?
For many women with uncomplicated pregnancies, gentle pregnancy-appropriate yoga may be suitable at 16 weeks. From around this stage, prolonged exercises lying flat on your back should be avoided or modified.
Can beginners do yoga during the second trimester?
Beginners may be able to start gentle prenatal yoga during the second trimester. Start gradually, avoid strenuous routines and consider working with an instructor trained in prenatal yoga.
Which yoga poses should I avoid during pregnancy?
Avoid or modify movements that involve prolonged flat-on-back positions, significant fall risk, excessive twisting, overheating or anything that causes pain or discomfort. Your individual pregnancy may require additional modifications.
Can prenatal yoga help with back pain?
Gentle movement and pregnancy-appropriate strengthening may help some women manage common physical discomforts, but persistent or severe back pain should be assessed by a healthcare professional rather than treated solely with yoga.
How often can I do prenatal yoga?
The appropriate frequency depends on your existing fitness level, pregnancy and overall activity routine. Rather than focusing only on the number of yoga sessions, aim for regular, comfortable physical activity and follow your healthcare provider's advice.
Can I continue my regular yoga practice during pregnancy?
You may be able to continue an established yoga practice with appropriate modifications, but some poses, intensity levels and positions may no longer be suitable. A prenatal yoga instructor can help adapt your routine.
