Pregnancy is an amazing journey, but it comes with its challenges. One thing that's important during this time is staying active for both you and your baby's health. That's why we're excited to share our Maternity activewear  buying guide with you. 

In this guide, we'll talk about why maternity activewear is different, when to start wearing it, and how to choose the right pieces for you. Whether you're a fitness pro or just starting out, we're here to help you feel confident and comfortable during this special time. Let's get started.

How is maternity activewear different from regular activewear?

There are a few key differences between maternity activewear and regular everyday activewear. Here’s what to look out for:

Stretchy fabrics 

Maternity activewear typically utilises fabrics with higher elasticity compared to regular activewear. These fabrics often include blends of spandex, elastane, or other stretch materials. The increased stretchiness allows the clothing to expand comfortably over a growing belly without losing its shape or becoming too tight. Additionally, these fabrics offer gentle compression to support muscles and promote blood circulation, which can be particularly beneficial during pregnancy.

Adjustable waistbands

One of the most notable features of maternity activewear is its adjustable waistbands. Unlike regular activewear, which often has fixed waistbands, maternity versions incorporate elastic or drawstring waistbands that can be adjusted to accommodate the changing size of the abdomen. This feature ensures a snug yet comfortable fit throughout pregnancy, preventing the waistband from digging into the belly or causing discomfort during movement.

Extra support 

Pregnancy places increased strain on certain areas of the body, particularly the abdomen and breasts. Maternity activewear addresses this by providing additional support in these key areas. For example, maternity sports bras are designed with wider straps, adjustable closures, and extra reinforcement to support the growing bust and reduce strain on the back and shoulders. Similarly, maternity leggings and tops may feature built-in belly panels or strategic seam placements to offer support and stability to the abdomen during physical activity.

Roomier design 

Maternity activewear is designed with a more generous cut and roomier proportions compared to regular activewear. This allows for ample space to accommodate the expanding belly and breasts without feeling restrictive or constrictive. Additionally, maternity tops often feature longer lengths and curved hemlines to provide coverage and prevent riding up, ensuring comfort and confidence during workouts.


While maternity activewear is specifically tailored to the needs of pregnant individuals, it doesn't sacrifice style or versatility. Many maternity activewear brands offer a wide range of designs, colours, and patterns to suit different tastes and preferences. Additionally, maternity activewear is often crafted from moisture-wicking and breathable fabrics, making it suitable for a variety of activities beyond traditional workouts, such as yoga, walking, or running errands. This versatility allows expecting mothers to stay active and comfortable throughout their pregnancy journey, whether they're hitting the gym or simply going about their daily routine.

When should you start wearing maternity activewear?

The timing for transitioning to maternity activewear varies for each woman and depends on individual factors such as body changes and comfort levels. However, a general recommendation is to consider making the switch around the second trimester, typically between weeks 13 to 27 of pregnancy.

During the first trimester, many women may not experience significant changes in their body shape or size, and their regular activewear may still provide adequate comfort and support. However, as the pregnancy progresses into the second trimester, the abdomen begins to noticeably expand, and some women may start feeling discomfort or tightness in their regular workout clothing.

By the second trimester, wearing maternity activewear can offer a better fit and accommodate the growing belly more comfortably. Maternity activewear is designed with features such as stretchy fabrics and adjustable waistbands to adapt to the changing shape of the body during pregnancy.

While the second trimester is a common time to transition to maternity activewear, it's essential to pay attention to your body and make the switch whenever you feel that your regular activewear is no longer comfortable or supportive enough. Some women may find it necessary to switch earlier, while others may continue wearing their regular activewear for a longer period. Ultimately, the goal is to prioritise comfort and accommodate the changing needs of your body as your pregnancy progresses.

How to choose maternity activewear

Selecting maternity activewear is crucial for comfort and support during pregnancy. In this section, we'll offer simple tips to help you choose the right pieces that fit well and adapt to your changing body throughout your pregnancy.

How to choose maternity leggings 

When it comes to choosing maternity leggings, comfort and functionality are key. Here's a detailed guide to help you find the perfect pair:

Supportive waistband

Look for maternity leggings with a high-waisted design. This style provides gentle support for your growing belly and helps alleviate any discomfort caused by pressure on the abdomen. A wide waistband that sits comfortably above the belly ensures a secure fit without digging into your skin.

Stretchy and breathable fabric 

Opt for leggings made from stretchy and breathable materials such as spandex or a blend of cotton and elastane. These fabrics offer flexibility and allow for unrestricted movement, making them ideal for various physical activities. Additionally, breathable fabrics help regulate body temperature and keep you comfortable during workouts.

Adjustable features 

Consider leggings with adjustable waistbands or built-in belly panels. These features allow you to customise the fit according to your changing body shape and preferences. Adjustable waistbands typically feature elastic or drawstring closures that can be tightened or loosened as needed, providing flexibility and ensuring a snug yet comfortable fit throughout your pregnancy.

Seam placement 

Pay attention to the placement of seams in the leggings. Flatlock seams or seamless construction can help minimise chafing and irritation, especially in areas prone to friction during movement. Smooth, seamless leggings provide a sleek silhouette and prevent discomfort caused by rubbing against the skin.


Choose leggings that can transition seamlessly from workouts to casual wear. Versatile designs in neutral colours or classic patterns allow you to mix and match with other maternity activewear or everyday clothing. This ensures that your maternity leggings remain practical and stylish for various occasions.

Size and fit

Refer to sizing charts provided by the brand and consider going up a size to accommodate your expanding belly and hips. Maternity leggings should fit comfortably without feeling too tight or restrictive. Aim for a snug yet flexible fit that provides support without constricting movement.

How to choose maternity workout shorts 

When selecting maternity workout shorts, prioritise comfort and flexibility to accommodate your changing body during pregnancy. Look for shorts with a wide, stretchy waistband that provides gentle support for your growing belly without digging into your skin. Opt for soft, stretchable materials such as spandex or a cotton-elastane blend that allow for unrestricted movement and keep you cool and dry during exercise. 

Consider styles with built-in support, adjustable features like drawstring closures, and a length that feels comfortable and provides adequate coverage. Choose versatile designs that can transition from workouts to casual wear, ensuring practicality and style throughout your pregnancy journey. 

By prioritising these factors, you can find maternity workout shorts that offer comfort, support, and flexibility to keep you active and comfortable during pregnancy.

How to choose maternity workout tops 

When choosing maternity workout tops, prioritise comfort, support, and flexibility to accommodate your changing body during pregnancy. Look for tops with ample room in the chest and abdomen area to accommodate growth without feeling constricted. Opt for moisture-wicking fabrics that help regulate body temperature and keep you dry during workouts. 

Consider styles with adjustable straps or side ruching for a customizable fit throughout pregnancy. Choose tops with built-in shelf bras or supportive panels to provide additional support for your breasts. 

Select versatile designs that can transition seamlessly from workouts to casual wear, ensuring practicality and style throughout your pregnancy journey.

Other things to think about when buying maternity activewear

When purchasing maternity activewear, there are some other things to consider to ensure comfort and functionality throughout your pregnancy. 

Firstly, invest in supportive undergarments such as maternity sports bras to minimise discomfort and provide adequate support for your changing body. Pay attention to sizing charts and consider going up a size to accommodate your expanding belly and breasts, ensuring a comfortable fit. 

Choose versatile pieces that can transition seamlessly from workouts to casual wear, maximising their value and versatility. Additionally, prioritise durable materials and quality construction to ensure longevity and performance, especially if you plan to continue wearing the activewear post-pregnancy. 

Finally, consider your personal style preferences and choose designs that make you feel confident and motivated to stay active during this special time.

Top tips for working out safely while you’re pregnant

Here are some top tips for exercising safely during pregnancy:

  1. Consult with your healthcare provider before starting or continuing any exercise routine during pregnancy. Your doctor can provide personalised recommendations based on your medical history and pregnancy progression.

  2. Listen to your body and modify exercises as needed to avoid overexertion or strain. Pay attention to signs of discomfort, dizziness, or shortness of breath, and adjust your intensity or duration accordingly.

  3. Stay hydrated by drinking plenty of water before, during, and after exercise. Dehydration can increase the risk of overheating and pose potential risks to you and your baby.

  4. Take frequent breaks to rest and replenish energy levels, especially during longer workout sessions. Allow your body time to recover and avoid pushing yourself beyond your limits.

  5. Incorporate low-impact activities such as swimming, walking, or prenatal yoga into your routine. These exercises are gentle on the joints and provide cardiovascular benefits without placing undue stress on your body.

  6. Avoid activities with a high risk of falling or abdominal trauma, such as contact sports, skiing, or horseback riding. Opt for safer alternatives that reduce the risk of injury to you and your baby.

  7. Pay attention to your posture and alignment during exercise to maintain stability and prevent strain on your muscles and joints. Avoid exercises that involve lying flat on your back after the first trimester, as this position can restrict blood flow to the uterus.

  8. Wear supportive footwear and maternity activewear that fits well and provides adequate support for your changing body. Invest in a supportive maternity sports bra to minimise discomfort and reduce breast movement during exercise.

  9. Gradually increase the intensity and duration of your workouts over time, rather than pushing yourself too hard too quickly. Aim for a moderate level of intensity that allows you to comfortably carry on a conversation while exercising.

  10. Trust your instincts and stop exercising if you experience any unusual symptoms or discomfort. If you have any concerns about your exercise routine or pregnancy, consult with your healthcare provider for guidance and reassurance.
