The three months after childbirth, or “fourth trimester,” can feel like two major events happening at once: your body is recovering from pregnancy and birth, while your daily life suddenly requires constant lifting, carrying, feeding, bending, and very little sleep.
This is not the time to “bounce back” or rush into intense workouts. It is a time to rebuild connection, restore core and pelvic floor function, and gradually prepare your body for the very real physical demands of early parenthood.

Quick Answer: Fourth-trimester exercise should focus on recovery first, not rushing back into intense workouts. Start with gentle strategies like neutral alignment, 360° Breathing, Pelvic Floor Activations, and movements that mirror daily parenthood tasks. As your body heals and you receive medical clearance, you can gradually add low-to-moderate strength training to rebuild function, support your core and pelvic floor, and prepare for the physical demands of early parenthood.
Key Physical Changes that Occur in the Early Postpartum Period
As you adjust to life as a new parent, your baby is adjusting to life outside the womb. It is common for this stage to come with “big” feelings. You are no longer responsible only for yourself. You now have another human being who depends on you for survival, and that new reality can bring physical, emotional, and psychological challenges.
Physically, your body’s tissues are healing (at different rates), from the uterus shrinking to skin remodeling. Weight loss, typically one of the most desired consequences of being postpartum, takes time, as does the reconnection to the core and pelvic floor. If you had tearing, an episiotomy, or a C-Section delivery, those tissues also need time and support to heal.
Hormonal levels also fluctuate significantly during this stage, which can contribute to emotional and psychological changes. Some symptoms may be consistent with the very common “Baby Blues,” while others may point to a Perinatal Mood and Anxiety Disorder (PMAD). Learning the difference can help you get the support you need during this challenging time.
General Guidance for Exercise in the Fourth Trimester
Your initial priority after having a baby is recovery.
Even though you may be on 24/7 baby duty and entirely focused on caring for someone else, your body still needs time, care, and support. This is not the stage to rush back into intense exercise. Early postpartum recovery requires patience, and honoring that process can actually help you return to stronger movement more efficiently.
When the body is pushed into higher-intensity training before it is ready, tissues that are still healing may not be prepared to manage those stresses. That can increase the risk of pain, injury, or delayed recovery.
In this stage, slow is fast.
During the first few weeks postpartum, the goal is to begin restoring connection with your deep core and pelvic floor, support healing, and gradually reintroduce movement in a way your body can tolerate.
After 2-4 weeks — or potentially longer depending on your labor and postpartum experience — you may feel ready to begin more structured workouts. Before doing so, get clearance from your medical provider to ensure stitches have healed, bleeding has ceased, and any other relevant medical markers have been cleared.
When first resuming exercise, keep the intensity low as you reorient yourself to a body that has undergone tremendous change. Pregnancy hormones remain in your system for months postpartum, and longer if you are breastfeeding or pumping, so pay attention to how movements feel now versus how they felt before.
Let your intuition and your form guide your progress.
Best Training Strategies and Exercises for the Fourth Trimester
The early postpartum period can feel overwhelming, and it may be difficult to focus on exercise, even if you are motivated to move. Start slowly. The goal is not to force yourself back into a workout routine, but to rebuild connection, restore function, and gradually increase your capacity.
1. Care for Yourself
Self-care may sound simple, but in the fourth trimester, it can be surprisingly difficult. New parents are often navigating constant care demands, disrupted sleep, feeding challenges, household responsibilities, and pressure from the “bounce back” culture. Social media can add to that pressure by making early parenthood look calm, polished, and perfectly balanced. For most people, that is not the reality.
In this stage, care may look small. A shower. A few minutes doing some feel-good breastfeeding stretches. A walk without the baby. A podcast while you fold laundry. These moments may not feel like much, but they can help restore a sense of connection to yourself during a season when so much of your energy is directed toward someone else.
2. Practice Neutral Alignment
One of the most effective ways to support your recovery does not involve exercise at all. It involves how you position, or “align,” your body throughout the day while sitting, standing, feeding, carrying, and bending over. When your body is in neutral alignment (as shown below), it reduces unnecessary stress on your soft tissues, which can help them heal more efficiently.
When sitting, focus on maintaining a straight line between your ear, shoulder, and hip, as pictured below. This can be difficult when you are exhausted, so set up your feeding area with enough support to help you stay comfortable.
When bending over, aim to keep that same ear-shoulder-hip alignment. This helps protect your core and minimize low back stress as you move through daily parenthood tasks.
3. Restore Strength to Your Deep Core
You can begin reconnecting with your deep core as soon as you feel comfortable. The first technique to focus on is 360° Breathing, which we refer to as the #1 most effective core exercise. 360° Breathing helps re-establish coordination between the diaphragm, transverse abdominis, and pelvic floor. It also supports your nervous system, which can be especially valuable during a stage marked by sleep loss, stress, and constant caregiving. Watch the video below to learn how to perform 360° Breathing and, importantly, how to incorporate it into your movement throughout the day.
The pelvic floor also needs specific attention, as it has managed a tremendous amount of stress throughout pregnancy and delivery, regardless of birth method. We recommend practicing Pelvic Floor Activations (PFAs), which help restore both contraction and lengthening capacity through the pelvic floor. Watch the video below to learn a 4-step process to first find your pelvic floor muscles (HINT: your “pee-stopping” muscles are only the front) and how to coordinate their movement with your breath for PFAs.
4. Balance Strength Training Across 5 Categories
After you get clearance to resume exercise and feel ready to do so, strength training is the most beneficial type of exercise to focus on. To ensure a balanced, total body workout, aim to include movements from the 5 strength training categories below:
- Upper Body Push: Moving weight away from your body, or moving your body away from an object. Examples include overhead presses, baby lifts, chest presses, and incline push-ups.
- Upper Body Pull: Pulling weight toward the body, or the body toward an object. Examples include standing rows, reverse flyes, and straight-arm pulldowns.
- Lower Body Bilateral: When both legs perform the same movement at the same time, such as squats and deadlifts.
- Lower Body Unilateral: When one leg performs a movement while the other performs a different function, such as reverse lunges, step-ups, or single-leg deadlifts.
- Core: Moves that target the core while maintaining neutral alignment, such as Turkish getups, kneeling side planks, and bird dog (quadruped arm and leg reach).
✓NOTE: Given the flexed position that nursing, feeding, and frequent baby carrying can encourage, pulling movements are especially beneficial to prioritize.
Aim for 2-3 sets of 10-15 reps of each move (time-permitting) at low-moderate intensity initially, then slowly progress to heavier weights as long as you can maintain good form.
5. Incorporate Exercises Specific to Your Daily Tasks
One of the best ways to prevent aches and pains in the fourth trimester is to train for the activities of daily living (ADLs) that you perform on repeat as a new parent. Think: baby lifts, ground getups, ground pickups, bath time kneels, crib reaches, feeding positions, and repeated carrying. Practicing these patterns helps your body manage daily stress more effectively, which can translate to easier movement and fewer aches and pains. Begin with a lighter load, then gradually add resistance to mimic your adorable “load” as your baby continues to grow.
The Bottom Line: Slow is Fast
The fourth trimester is not about rushing back. It is about rebuilding from the inside out, restoring connection with your body, and gradually developing the strength you need for the physical demands of early parenthood. With patience, smart movement, and the right support, this stage can become the foundation for a stronger, more capable recovery.
