Can You Do HIIT Postpartum? A Fitness Guide for Women Post-Baby

A Guest Blog Post by Laura Pearson

Many new moms have questions about returning to their fitness routines after giving birth. It takes a while to recover, and sometimes even walking can be strenuous. Returning to activities like high-intensity interval training (HIIT) may seem off the radar, although it’s celebrated as one of the most efficient workouts available. It helps people build strength and endurance while burning calories in a short amount of time.

However, your body undergoes significant changes after pregnancy. You need time to heal, rebuild strength and restore balance before joining intense exercise routines. Can you do HIIT postpartum?

Understanding Your Postpartum Body

Pregnancy and childbirth trigger remarkable physical changes. Your abdominal muscles stretch to accommodate your growing baby, your pelvic floor bears extra weight, and your joints and ligaments loosen due to hormonal shifts. Even after delivery, these changes don’t reverse overnight.

You might face several postpartum challenges that affect your return to exercise:

Diastasis recti affects many new mothers, causing separation of the abdominal muscles. This makes core exercises challenging.
Pelvic floor weakness can result in urinary incontinence, prolapse or discomfort during exercise.
Hormonal fluctuations continue to influence your energy levels, mood and recovery.
The constant care newborns require often results in fatigue and disrupted sleep patterns.

Why Exercise in Postpartum Recovery Matters

Exercise isn’t merely about regaining your pre-pregnancy fitness level — it benefits your overall well-being.

Your mood and mental health improve through the release of endorphins, which can help reduce postpartum depression and anxiety. There’s also a notable increase in energy levels to combat fatigue and enhance overall well-being. The core and pelvic floor muscles strengthen, reducing discomfort and improving function. You’ll also note better posture and alignment to correct muscle imbalances brought on by pregnancy.

If you’re feeling emotionally overwhelmed during this transition, remember that it’s OK to see a therapist. These trained professionals provide tailored support and guidance to help you live your best life.

When considering HIIT postpartum, you’ll need to evaluate several factors, including:

The delivery method.
Overall recovery.
Your previous fitness level.

When Can I Start HIIT After a C-Section?

For vaginal births, you can generally start walking a few days postpartum, but only after receiving clearance from your health care provider. However, this timeline varies significantly based on your healing and circumstances.

If you’ve had a C-section, your recovery timeline will be longer since it’s considered major abdominal surgery. You will need to get the approval of your doctor to resume HIIT.

In those initial weeks, concentrate on building a foundation with gentle walking to improve circulation and prevent blood clots. Practice deep breathing exercises to reconnect with your core and perform pelvic floor exercises to rebuild strength from the inside out.

Signs You’re Ready for HIIT

Before increasing your workout intensity, ensure you can:

Complete daily activities without pain or fatigue.
Maintain proper form during basic exercises.
Control your bladder during movement.
Perform at least 10 squats.
Feel strong and stable in your core.

What Exercises Should You Not Do Postpartum?

During the early postpartum period, certain exercises can delay recovery or increase injury risk. You should avoid:

Traditional ab exercises like crunches and situps can worsen diastasis recti and strain weak abdominal muscles. High-impact jumping exercises, like burpees and box jumps, may strain the pelvic floor, which may not be ready to handle the exertion. Heavy weightlifting could place excessive strain on your healing body. Instead, practice low-impact cardio, lunges and squats until you’ve rebuilt adequate core strength.

It’s best to get 150 minutes of moderate weekly exercise for overall health maintenance. However, postpartum women should approach these targets gradually, listening to their bodies and adjusting intensity as needed.

Creating a Safe Return to HIIT

Once you’ve regained foundational strength and received medical clearance, you can incorporate HIIT to support your postnatal body.

Start with modified movements, swapping high-impact exercises for lower-impact variations. Begin with short sessions and gradually increase duration. Prioritize proper breathing techniques and engage your deep core muscles. Importantly, monitor your body for warning signs. Prioritize recovery days and adequate hydration.

Red Flags to Watch For

Stop exercising and contact your health care provider if you experience:

Increased bleeding or discharge.
Pain during or after exercise.
Feelings of pressure in your pelvic area.
Unusual fatigue or dizziness.

The Importance of Professional Guidance

Every postpartum journey is unique. What works for one person might not work for another. To be on the safer side, consider working with a pelvic floor physical therapist to assess your recovery and propose safe exercise progression. We have some great recommendations for Maryland area moms on our resource page. Plus, consider coming to our March Momness event to meet several pelvic health therapists and a personal trainer who specializes in moms.

Certain organizations provide valuable resources and support for women navigating various aspects of motherhood — even for those going through pregnancy or infant loss to achieve physical recuperation. Furthermore, they understand that postpartum recovery should consider the physical, mental, emotional and social elements for holistic well-being.
