Jill and I met a few years back after she invited me to a virtual coffee date to learn about her services. I penciled in 30-minutes and hoped to leave with information about her women’s fitness practice to share with the women in my perinatal therapy practice. Long story short, we ended up meeting for over 2-hours and bonding over our shared perspectives about holistic, human-centered healing and support.
I left our coffee date with three major insights:
Jill is deeply knowledgeable, thoughtful, and grounded. She has both personal and professional experience with pregnancy, the demands of motherhood, perimenopause, and menopause. Additionally, she is always learning and growing her skills. She holds multiple certifications in perinatal and menopause health and fitness coaching and adolescent female athlete coaching. This December she’ll earn her Masters of Science in Exercise Science and Integrated Wellness through Bastyr University.
She values authentic, in-person, and face-to-face communication, and she strives to stay away from social media as much as possible. In a world where physical image can be everything and where she is supporting women with their bodies, it feels extra special to receive care from someone with this philosophy.
She truly loves what she does. She loves seeing women feel strong and confident in their bodies, find their voice, and feel empowered.
Her skill, education, and focus on human connection is exactly what makes her stand out in the local community of women focused healthcare services.
What Makes Jill Sinkula Different
Jill Sinkula is a women’s fitness coach who specializes in working with adolescent females, pregnant and postpartum women, and women who are experiencing perimenopause or menopause on Bainbridge Island. Her goal is always to meet people where they are and create an approach that supports the whole person and feels achievable and sustainable.
Jill doesn’t use scales or weight tracking as a part of her approach to fitness coaching. She believes we spend enough time focusing on numbers already.
Her coaching takes a whole-person approach, considering movement and exercise alongside breathwork, personal goals, self-talk, and the environments and relationships that can either support or challenge well-being.
Q&A with Jill Sinkula, Women’s Fitness Coach
Q: Can you share a bit about yourself and what led you to create Bainbridge Island Women’s Fitness?
A: My passion for women’s fitness sparked during my first pregnancy. I felt discouraged by the lack of knowledgeable, supportive resources for expectant mothers, and I quickly realized that many women shared this frustration. That experience inspired me to launch my first coaching business, dedicated to creating a safe, empathetic space where women could reclaim their strength and autonomy.
Years later, as I entered perimenopause, I found myself once again facing a major life transition with limited support. That experience led to the rebirth of my coaching practice as Bainbridge Island Women’s Fitness, with a mission to support women through all of life’s phases. from pregnancy and postpartum to perimenopause and beyond.
Q: What kinds of challenges do you help women with, and at what stages?
A: I support women and girls through important life transitions, including adolescence, the perinatal period, and the menopause transition. Some are just starting to prioritize self-care, while others have a plan and need help fine-tuning it. Wherever they are, we work together to create an approach that feels good and actually fits their life.
Every session is flexible, based on how they’re feeling that day, physically, mentally, and emotionally. Whether it’s navigating early motherhood, midlife changes, or the transition through adolescence, I’m here to help them feel strong, supported, and confident in navigating these changes.
As I expand my work with younger girls, I’m passionate about helping them understand their changing bodies and menstrual cycles, and how nutrition and training can support their health and athletic performance throughout the cycle. I want girls to feel confident listening to their bodies and understand that a healthy menstrual cycle is an important part of overall well-being, not something that should be compromised in pursuit of athletic performance. My goal is to help girls develop a positive relationship with movement, nutrition, and their bodies while building confidence and strength.
Q: How does someone know they could benefit from working with you? When is the right time to reach out?
A:I encourage women to reach out anytime. There’s no “perfect” moment to start putting yourself first. Whether you’re curious, feeling stuck, or just looking for support, I’m here. You’ll find lots of helpful information about my offerings on my website, and I also offer a free 30-minute video consultations. It’s a great, no-pressure way to connect and see if we’re a good fit for each other.
Q: Do you have a particular philosophy or framework that guides your approach?
A: My philosophy is to serve the client in front of me. No matter how much education or experience I have, it’s essential to set aside assumptions and really listen to each person’s needs, desires, and what brought them here. From there, I tailor my programming by combining their goals with my practical knowledge to create a plan that truly fits them.
I want women to focus on how they feel, what they’re capable of, and the progress they’re making toward their personal goals.
Q: What’s one myth about women’s health that you wish more people knew wasn’t true?
A: One of the biggest myths, and one that impacts nearly every aspect of women’s health, is the belief that women are simply “smaller men.” Historically, much of the research informing fitness, nutrition, and supplementation has been conducted on male subjects, with women often underrepresented in these studies. While that is beginning to change, we still have gaps in our understanding of how women’s unique physiology influences health, fitness, and performance.
Thankfully, there are trailblazers working hard to close these gaps, and I’m incredibly grateful for their efforts. My goal is to continuously educate myself through science-backed research while also actively listening to women’s real-time experiences. I aim to share accurate, relevant, evidence-informed information with my clients and help them make informed decisions about their health.
Q: How is your support different from what people might find in other fitness spaces?
A: I offer is a much more individualized experience. I take a lot of pride in observing how a person’s body moves and responds in the moment. But beyond the physical, I always prioritize my clients’ mental health and emotional well-being ahead of any workout plan. I check in regularly during sessions and use that feedback to guide everything we do.
Sometimes, that means making space for emotional release, because I truly believe physical and emotional well-being are deeply connected. My goal is always to meet each client exactly where they are.
Q: What does support from you typically look like for someone feeling overwhelmed or unsure where to start?
A: I provide as much—or as little—support as each person needs. Sometimes that means helping someone find ways to incorporate more movement into a busy schedule. Other times, it might mean working through negative self-talk, setting realistic personal goals, finding ways to manage stress, or creating routines and an environment that better support their well-being. If they’re interested, I can also offer general nutrition guidance within my scope of practice as part of their overall wellness plan.
For example, someone might want to move more but feel overwhelmed by the idea of exercising five days a week. We’d work together to find what’s realistic and where movement can fit naturally into their life. If someone really dislikes traditional exercise, we’d explore activities they actually enjoy and build movement around those instead.
For someone who wants more structure, I can provide individualized workouts and regular sessions, while also checking in on how they’re feeling physically, mentally, and emotionally. The plan can evolve based on what they need from week to week.
Q: What’s one thing you wish all women knew about fitness during the early postpartum period?
A: I know it’s not always what new moms want to hear, but rest truly is your best friend in the early postpartum period. Your body has done something incredible, and it needs time to recover.
Also, something we don’t talk about enough: hormonal shifts during this time can feel like a wildfire! It’s completely normal to experience a wide range of emotions as your body adjusts.
Remember, your body needs time and grace to recover. Things don’t have to “bounce back” right away. You are still you, but now you’re navigating a beautiful new chapter.
And one more thing: no one has stronger backs and arms than mothers. Truly. Here’s to you.
I guess that’s four things. ;)
