Exercising throughout your pregnancy is not only possible, it’s potentially beneficial for both you and your baby – but certain modifications are a must for exercising safely.
Follow these pregnancy exercise guidelines and you can reap the rewards of regular exercise while doing what’s best for you and bubs.
The most important thing about exercise during pregnancy is to be clear about what you hope to achieve. Pregnancy is generally the time for maintenance, not for striving for new fitness goals or working out at high intensity.
Erin Maw, Les Mills Program Director, says she reset her approach to exercise when she became pregnant. “I let go of my expectations and changed my mindset to focus on doing what I can do. I left my ego at the door and started prioritizing strength training and low impact cardio like stationary cycling.”target=”_blank”
Fellow trainer Mandi Hirini also switched up her workout routine. “I started taking each day as it comes, accepting what my body needs.” This means embracing a variety of different training modalities like mobility, minimal impact cardio and strength. “I prioritize strength training, because it not only helps to keep my mood and energy up, but keep my core as functional as possible. Strength training helps my pregnancy be pain free, will help empower my birth experience and creates a positive foundation for whatever postpartum recovery may be ahead.”
The transversus abdominis muscle (TVA) is a deep muscle in the abdominal region that is important in core stability and support. Strengthening the TVA during pregnancy is particularly valuable, as it can help alleviate back pain, and support the spine and pelvis.

However you choose to move during pregnancy, make sure your obstetric caregiver is aware of your fitness activities, drink plenty of water during exercise and stop immediately if you ever feel dizzy or uncomfortable.

Many LES MILLS™ workouts can be enjoyed during pregnancy. Simply choose the options where needed.
BODYBALANCE™ and a low impact version of LES MILLS TONE™ can be started for the first time during pregnancy. These workouts both include plenty of exercises that are appropriate for expectant mothers looking to make healthy lifestyle changes. During BODYBALANCE, try to wriggle through your poses and make certain you are not too aggressive with your stretches – the hormones released during pregnancy can loosen up your joints. Stop immediately if you ever feel dizzy.

If you’re keen to maintain muscle tone during pregnancy, BODYPUMP™ is a great option as it uses lighter weights and a reduced range of motion compared to other resistance training modalities. When it’s no longer comfortable to lie flat on your back in a BODYPUMP workout, turn your bench into an incline bench by stacking more risers at one end. Workouts like LES MILLS STRENGTH DEVELOPMENT™ and LES MILLS FUNCTIONAL STRENGTH™ – where there are dynamic and explosive movements – are not recommended for those new to this type of training during pregnancy. You might like to try Les Mills’ Strength for Pregnancy workouts available exclusively on LES MILLS+.
Working your core in LES MILLS CORE™ and doing workouts like LES MILLS PILATES™ and LES MILLS SHAPES™ should be safe in the first and second trimester, as this type of training has been shown to minimize disruption of the abdominal wall during pregnancy. However, there are a few adjustments you should make when you can. When it’s no longer comfortable to lie flat on your back, you should switch to working your abs with 4-point kneeling, supporting yourself on your elbows (ensuring you keep the chest lifted) or rolling over to do hover or plank. Another option is to try the Barre and Pilates for Pregnancy workouts available exclusively on LES MILLS+.
If you’ve already been doing cardio workouts like BODYATTACK™ and BODYSTEP™, it should be safe to continue while pregnant. Use the low-impact options that feel right for you. During BODYSTEP, decrease the number of risers you use and make sure you have a stable base of support by ensuring your foot is always planted firmly on the step and keeping a slightly wider base of support.
During cycle workouts like RPM™ and THE TRIP™, you should modify the intensity by taking regular breaks, reducing resistance and avoiding the standing positions as you feel the need to.
The following workouts are not recommended during pregnancy:
