In this episode of Pursuit of Wellness, Mari Llewellyn shares her postpartum fitness journey after C-section recovery. She discusses how her approach to rebuilding strength differs from her 2017 transformation, now prioritizing consistency and sustainability over perfection while managing the demands of new motherhood. Mari covers her training structure, the challenges of working out with limited childcare support, and her use of modern tools like peptides and targeted supplementation.
Mari addresses the myth that breastfeeding leads to automatic weight loss, explaining how the intense hunger and energy depletion made fitness progress difficult until after she stopped nursing. She also examines the mental health aspects of postpartum recovery, including external pressure to "bounce back" and her own shifting identity and confidence. Throughout, Mari emphasizes that her fitness goals now center on family wellbeing rather than aesthetic achievement, with exercise serving as a tool to be the best version of herself as a mother and partner.

After her six-week C-section recovery period, Mari Llewellyn began her postpartum fitness journey cautiously, starting with two days a week of light weight training before progressing to a three-day split of upper body, lower body, and conditioning sessions. She avoids high-impact activities like jumping and running due to lingering discomfort, instead incorporating functional exercises like wall balls and farmer's carries for conditioning.
Mari's recovery focuses on rebuilding grip and core strength—both severely diminished after birth—through compound movements like squats and lunges that naturally engage the core, alongside dedicated ab work and pelvic floor therapy. Working with a trainer in Austin, she schedules sessions when her nanny arrives, allowing her to focus entirely on training without the stress of workout planning while managing childcare responsibilities.
Mari's current postpartum journey contrasts sharply with her 2017 transformation, when fitness was her top priority and she devoted extensive time to gym sessions, meal prep, and macro tracking. Now as a new mother, she emphasizes consistency and sustainability over perfection, relying on the intuition and knowledge gained over years of training rather than obsessing over details or tracking food.
Despite having access to advanced resources like updated fitness technology and peptides unavailable during her original transformation, Mari adjusts her expectations. She understands that postpartum fitness is about adapting to her new reality and focusing on gradual progress rather than reclaiming her pre-pregnancy body.
With limited family help, Mari relies on hiring a nanny who arrives 30 minutes before her workout to ensure dedicated exercise time. Acknowledging this privilege, she advocates for alternatives like fitness apps, group classes with childcare, home workouts with baby carriers, or simply prioritizing walking.
Mari tracks her daily movement with a goal of 10,000 steps and monitors recovery with an Oura ring, paying attention to sleep, heart rate, and step count to balance fitness progress with the demands of new motherhood.
Mari emphasizes that automatic weight loss from breastfeeding is one of the biggest myths told to new mothers. Contrary to popular belief, she found her body holding onto fat during breastfeeding, losing only a single pound in thirty days despite expectations. The intense hunger from milk production's caloric demands made it nearly impossible to create the calorie deficit needed for weight loss, while the energy drain left her feeling depleted and unable to work out with previous intensity.
While Mari confirms that building muscle during breastfeeding is possible, the combination of extreme hunger, energy depletion, and hormonal changes makes weight loss difficult. After stopping breastfeeding and pumping, her fitness progress noticeably improved with increased energy and more productive workouts. She maintains a freezer stock of breast milk to supplement formula feeding, supporting her recovery without sacrificing her baby's nutrition.
Mari clarifies that her decision to stop breastfeeding was entirely for her mental health, not to accelerate weight loss. Ceasing her role as a "milk production machine" has been crucial for her overall wellbeing, relieving physical and emotional burdens that hampered her recovery and allowing for a more balanced state of mind.
Peptides have emerged as new injectable performance enhancers in the fitness world. Mari stresses the importance of working only with licensed coaches or clinics and maintaining transparency about peptide use, given the lack of FDA approval for many compounds and potential risks from incorrect sourcing.
After consulting with a licensed coach and reviewing blood work, Mari chose to try MOTS-C, a mitochondrial-derived peptide for metabolic and anti-aging benefits. She reports improvements in energy, exercise performance, cognitive clarity, and endurance after several days on a low-dose regimen, noting that unlike GLP-1 compounds, MOTS-C doesn't suppress appetite and maintains healthy hunger cues.
Mari plans to add GHK-CU for skin and hair health and BPC157 for gut healing and postpartum recovery. She advocates introducing peptides individually to safely monitor effects and identify any adverse reactions.
Mari maintains a consistent supplement regimen including Bloom creatine for recovery and performance, electrolytes, magnesium, fish oil, choline, and vitamin D. She relies on raw protein bars as a daily nutrition staple, having consumed them consistently for five years through pregnancy and postpartum.
Mari describes intense scrutiny over her postpartum body, noting that people assess whether she's "bouncing back" when they see her. This adds to her feeling like "a stranger in your body" while struggling to find confidence. She highlights the unrealistic expectation for postpartum women to both breastfeed extensively and lose weight quickly, finding these demands incompatible given the physical and hormonal demands of nursing.
Mari firmly rejects toxic diet culture and extreme online standards, stating she's "pretty good at ignoring that." Her fitness goals stem from wellness, not pressure to "bounce back"—exercise and nutrition help her feel like the best version of herself, which benefits her as a mom and partner. While aesthetics play some role, Mari views this as reasonable self-care rather than harmful body obsession, maintaining that "it's not always about aesthetics. And even if it is a little bit about aesthetics, I think that's okay."
Motherhood has shifted Mari's identity and confidence. She feels more certain of her boundaries and priorities, less concerned with people-pleasing or judgment from others. However, her body still feels unfamiliar, affecting her confidence in dressing and going out. Mari sums up this duality: she is confident in her priorities and values, but still navigating her physical identity and adapting to her postpartum appearance.
Mari's motivation for fitness has changed dramatically since 2017. Her focus is now on family, with every decision considering her son Kai first. Exercise and nutrition serve as tools to make her the best version of herself, directly benefitting her parenting and partnership. She emphasizes that maintaining her wellbeing allows her to pour energy into her family rather than feeling depleted, especially after experiencing daily anxiety and depression while breastfeeding.
The realities of motherhood mean Mari has much less personal time. She intentionally schedules workouts into small windows—typically after early morning time with Kai around six or six-thirty—so the majority of her day can be spent with him. This schedule enables her to concentrate on fitness without it lingering as an unfinished task, while embracing a patient and sustainable approach to progress.
Motherhood has permanently changed Mari's physique and strength level, leading her to establish new, realistic expectations. After losing 25 pounds post-birth, she now prioritizes muscle recovery and performance over scale numbers. Mari advocates for light exercise during pregnancy to support mindset stability and make the transition into postpartum recovery feel less overwhelming physically and emotionally.
1-Page Summary
After waiting the recommended six-week recovery period following her C-section, Mari Llewellyn began her postpartum fitness journey by gradually introducing weight training. Initially, she started with two days a week using lighter weights, focusing on retraining her body and rebuilding a foundation for strength. Over time, she worked up to a structured three-day-per-week split, consisting of dedicated upper body, lower body, and conditioning sessions.
Mari’s postpartum training plan is marked by caution and intentional progress. She avoids high-impact activities, such as jumping or running, due to lingering discomfort, particularly with her breasts not feeling fully recovered. For conditioning, she incorporates functional and cardio-oriented exercises like wall balls, ski machine intervals, and farmer’s carries instead of traditional intense cardio.
While pregnant, Mari maintained moderate strength training, being mindful of avoiding exercises that placed undue strain on her core or involved significant impact, like hip thrusts. After birth, she prioritized restoring grip and core strength, both of which were notably diminished—she recalls barely being able to do a plank or activate her core muscles at first. Her trainer in Austin plays a crucial role in helping her rebuild, providing structure and removing the need for her to plan workouts, which is vital as she balances fitness with caring for her baby.
Mari’s recovery involves slow, steady introduction of core exercises, especially mindful as a C-section mother. She emphasizes compound, core-engaging movements such as squats, RDLs, and lunges, which naturally require core stabilization, alongside slow progressions in dedicated ab work and pelvic floor therapy.
This new chapter also requires logistical adjustments. Mari trains in Austin, working with a trainer so she can transition directly into her session when her nanny arrives, freeing her from meal planning and workout prep stress. Her approach centers on making the process as efficient and consistent as possible given her limited childcare support and time.
Mari’s current postpartum journey stands in clear contrast to her 2017 transformation. Previously, fitness was her top priority—she devoted extensive time to gym sessions, meal prepping, and tracking macros. In that first journey, Mari was completely new to nutrition and exercise, learning everything as she went.
Now, as a new mother, she recognizes her priorities have shifted. Fitness must fit around her responsibilities, so she emphasizes consistency and sustainability rather than perfection or intensity. She no longer obsesses over every detail or tracks her food, relying instead on the intuition, knowledge, and experience gained over years of training.
With this new perspective, Mari starts her postpartum fitness phase armed with advanced knowledge of nutrition, recovery, and access to tools unavailable during her original transformation—such as updated fitness technology, innovative supplements, and peptides. Despite these resources, she adjusts her expectations, understanding that postpartum fitness is not about reclaiming her pre-pregnancy body, but adapting to her new reality and focusing on gradual, steady progress over pe ...
Postpartum Fitness Journey and Training Program Structure
Mari emphasizes that the common belief in automatic weight loss from breastfeeding is one of the biggest myths told to new mothers. Contrary to popular advice, she found herself unable to lose weight while breastfeeding and instead felt that her body was holding onto fat during this period. In fact, Mari believes she may have gained weight rather than lost any during the months she breastfed her son, Kai.
Despite widespread assertions that breastfeeding helps shed pregnancy weight quickly, Mari describes the complete opposite effect. Her body seemed to hold onto fat, and any meaningful weight loss stalled. She reports losing only a single pound in thirty days of breastfeeding, even though she thought the number would be much higher.
Mari also discusses how the intense hunger brought on by milk production prevented her from making any significant dietary changes. The calories needed for producing breast milk left her constantly hungry, making it nearly impossible to create the calorie deficit often needed for weight loss.
Mari shares that breastfeeding left her feeling extremely depleted and tired, impacting her ability to work out with the same intensity as before. While she still trained on a regular basis, the exhaustion and constant demands of caring for a newborn, combined with being in a hormonal fog, made losing weight extraordinarily challenging.
While Mari confirms that building muscle and maintaining fitness are possible during breastfeeding, the combination of extreme hunger, energy depletion, and hormonal changes makes weight loss difficult for many new mothers. Along with needing extra nutrition for milk production, being physically and emotionally tethered to her baby 24/7 made it hard to establish effective routines for significant fitness improvements.
After stopping breastfeeding and pumping, Mari finds that her fitness progress has noticeably improved. She notes an increase in energy and a greater capacity for more productive workouts, suggesting that the post-weaning phase offers a boost in both physical and fitness gains that were previously difficult to achieve.
Mari mentions she has a substantial freezer stock of breast milk, which now allows her to giv ...
Impact Of Breastfeeding On Weight Loss and Fitness
Peptides have emerged as one of the newest innovations in the fitness supplement world. Most peptides are a newer class of injectable performance enhancers that require thorough supplier vetting and professional guidance due to the lack of FDA approval for many, and the potential risks if sourced incorrectly. Mari stresses the importance of working only with licensed coaches or clinics, prioritizing transparency about peptide use, especially given their rising prevalence in the fitness industry. Many peptide compounds occur naturally in the body and, when supplemented, can amplify biological processes to support specific health and fitness outcomes.
After consulting with a licensed coach and reviewing a full blood panel focused on goals like hair loss, skin quality, gut health, energy levels, muscle gain, and fat loss, Mari chose to try MOTS-C—a mitochondrial-derived peptide gaining attention for its metabolic and anti-aging benefits. She describes her experience after several days on a low-dose regimen of MOTS-C, noting improvements in energy, exercise performance, cognitive clarity, and endurance with no adverse effects. MOTS-C supports overall metabolism and exercise output without acting as an appetite suppressant, which differentiates it from compounds like GLP-1. Mari reports feeling normal, healthy hunger cues and describes the peptide as a helpful boost in her postpartum fitness journey.
Looking ahead, Mari plans to integrate two additional peptides: GHK-CU, a copper peptide used for skin and hair health, and BPC157, known for its gut-healing properties and particularly promising for postpartum recovery. Her approach is to introduce each peptide individually, which allows her to appropriately identify and monitor for any adverse reactions. S ...
Peptides and New Supplement Tools in Fitness
Mari Llewellyn describes intense scrutiny over her postpartum body and the challenges she faces losing weight after childbirth. She notes that when people see her now, there’s a sense they are assessing how her body looks and whether she’s “bouncing back,” and conversations about workouts and weight loss arise quickly. This scrutiny adds to her feelings of bodily alienation, as she confides, “that's hard when you are already feeling like a stranger in your body and struggling to find confidence.”
She highlights the unrealistic standards imposed on postpartum women—to both breastfeed for an extended period while simultaneously losing weight and looking “amazing.” Mari finds these expectations incompatible, especially given the physical demands and hormonal shifts of breastfeeding, and believes the pressure often comes from ignorance about how hard it can be to be “glued to your baby 24/7” and in a fog. She identifies this tension as a source of struggle and emphasizes that a lot of the pressures put on postpartum women “just don’t even make sense.”
Mari firmly rejects toxic diet culture and the extreme standards she perceives online. She is aware that some online audiences may hold her to “a crazy standard,” but states that she’s “pretty good at ignoring that.” Instead, her fitness goals stem from a desire for self-improvement, not pressure to “bounce back.” She frames her postpartum fitness journey as motivated by wellness: exercise and nutrition help her feel like the best version of herself, which, in turn, benefits her as a mom and partner. “It’s not about bouncing back. It’s about allowing myself to be the best version of me for Kai, for myself, for my family.”
While aesthetics play a role—she admits wanting to feel good before a trip—Mari views this as reasonable self-care rather than harmful body obsession. She stresses her fundamentally healthy relationship with food and body image, noting, “Maybe here and there, when I lived in LA, I was a little too obsessive about it, but for me, exercise and nutrition helps me feel like the best version of myself and that makes me a better mom, it makes me a better partner.” She reiterates that her motivation is not solely about appearance: “It's not always about aesthetics. And even if it is a little bit about aesthetics, I think that's okay.”
Motherhood has shifted Mari’s sense of identity and confidence. She feels much more certain of her boundaries, priorities, and ability to advocate for herself and h ...
Postpartum Body: Mental Health, Identity, and Societal Pressure
Mari Llewellyn’s motivation for fitness has changed dramatically since 2017. Back then, her fitness journey stemmed from a sense of desperation and the desire to escape difficult times. Today, her focus is on family—every decision considers her son Kai first. Mari feels she is a much better mother when she is energized, focused, and present for Kai.
Exercise and nutrition now serve as tools to make her the best version of herself, directly benefitting her parenting and partnership. Mari emphasizes that when she feels good physically and mentally, she is happier and more capable as a mother and partner. She openly discusses the mental health challenges she faced while breastfeeding—including daily anxiety and depression—which underscored the importance of self-care. Maintaining her wellbeing allows her to pour energy into her family rather than feeling depleted.
The realities of motherhood mean that Mari has much less time for herself. She intentionally schedules her workouts into small windows so the majority of her day can be spent with Kai.
Her daily routine includes early morning time with her son. Kai typically wakes up around six or six-thirty, giving Mari a couple of hours with him before she works out at eight or nine in the morning. This schedule enables her to concentrate on her fitness without it lingering as an unfinished task and allows dedicated time with her son afterward. Mari embraces a patient and sustainable approach to progress, recognizing that balancing ambitious fitness goals with competing prio ...
