Our
Company Ethos

At Simply Strong 208, we believe fitness should be accessible, empowering, and designed to fit real life—especially for moms.

Too often, moms are told to “bounce back” or put their own needs last. We reject that mindset. Instead, we focus on moving forward with strength—building bodies that feel capable, confident, and resilient, no matter where you’re starting from.

Strength for Every Stage – Whether you’re just beginning your fitness journey, rebuilding after pregnancy, or leveling up your strength, we meet you where you are with safe, effective training.

Kid-Friendly, Mom-Focused – Motherhood shouldn’t be a barrier to fitness. That’s why Simply Strong 208 is a welcoming space where your kids can play while you train. No stress, no guilt—just movement that fits your life.

Support Over Judgment – Fitness should be encouraging, not intimidating. Our community is built on support, inclusivity, and lifting each other up—because strong moms create strong families.

A Community, Not Just a Gym – We’re more than just workouts. Simply Strong 208 is a place where moms connect, encourage each other, and build friendships while getting stronger together.

Sustainability Over Quick Fixes – We believe in realistic, long-term fitness—no crash diets, no unrealistic expectations. Just simple, effective strength training that works with your body, not against it.

Founded by Erin Longmire, Simply Strong 208 was created with one goal in mind: to give moms a space where they can prioritize themselves without guilt or obstacles. Whether you’re training in-person, joining a small group, or following monthly training on the app, you are welcome here.

"Erin is so welcoming, fun, and professional! I'm currently working out with other mamas (and kiddos) at Simply Strong 208, and it has been really fun. It's our happy hour! Her workouts are efficient, simple, and doable for any fitness level. If you're looking to start somewhere and want to be physically and mentally stronger, I highly recommend reaching out to Erin!! 💪"

Shirley W.
"I cannot say enough good things about Erin and her group fitness class. Erin is professional, organized, knowledgeable and positive. Her workouts are structured, challenging and progressive but in a fun way. I look forward to the workouts every week!! There’s really nothing like getting a bunch of likeminded mamas together for a workout while the kiddos play together ❤️ I HIGHLY recommend contacting Erin for personal training if you haven’t done so already."

Brittany F.

Taya C.
"Erin is absolutely amazing!! I am working out in a group right now with other mamas and it is perfect with our children there running around. She is always excited to help us in every way whether it is fix our form, teach us how to do a movement she has planned or even hold a baby so we can get the movement in! She is so great at helping each of us and sees if we need to be pushed more or if modifications are needed. I would recommend every mother in the area who is looking for either group training or one on one to Erin! She truly wants to help everyone get stronger and knows exactly how to do it!!"

Andrea V.
"I had so much fun working out here! Erin is amazing, friendly, and knowledgeable! Kids are welcome and have a little play area. A huge bonus for me as a mama! Thank you so much Erin!"

Ella F.
"Erin is the best trainer!!! So organized and positive. Cardio never works for me postpartum but these workouts actually feel like I’m strengthening my core. Plus she changes the circuits up a lot so it stays fun! The gym is so cute and clean. My kiddos play while I get an hour to focus on me! And Erin loves on my babies if they need some extra attention so I can finish the workouts. HIGHLY recommend her for any and all levels! She has been such a huge blessing to find in CDA!"

Marty F.
"Simply Strong & Erin are amazing!! I’ve never been one to work out, ever and she made it not intimidating. She provided easy to follow workouts at home that I can do with the kids. In just a few months I’ve seen results! Loosing baby weight, moving up in weights I can lift and my kid joining in on our workouts. Her home gym is the perfect set up where kids can play with one another and the plethora of toys she has while we workout. She’ll even hold a baby that’s fussy! Best of all, not only do your kids watch you model healthy habits, you’re not paying an additional fee for childcare while you work out! Love it, everything about it. Erin’s sweet, knowledgeable, encouraging, and she knows mamas! Highly recommend for anyone looking to start working out, or looking to get back into it, or just unsure of how to progress in their workout routines."

Briana P.
"Absolutely amazing experience!! Never having worked out in a setting like this before, with a group or a trainer, I didn't know what to anticipate. That being said, it has exceeded all my nervous expectations! The strength is incrementally coming, the comfort with pushing my body is becoming more familiar, and each time I show up, Erin 1000% shows up for us! She is engaged, cheery, encouraging, and quick to celebrate the growth with each baby step forward. She's knowledgeable and effortlessly customizes the routines to adapt to individual's personal needs. My children love going with me and playing with the kids along the side of the space too. After 5+ years of trying to adjust and accept my postpartum/motherhood body, it feels amazing to have found a space that allows me to prioritize healthy strength and goals, and that so greatly accommodates having my children with me too. Erin and Simply Strong 208 are a treasure and worth every penny!!! You won't regret it!"

Meredith A.
"Erin at Simply Strong 208 is an outstanding trainer- she is so kind, knowledgeable, and has created a fantastic environment to train. I've been training with her for several months now and shes taken something I used to find boring (weight training) and has made it exciting, challenging, and just something I LOVE doing. She is awesome at gently pushing me to do things I never thought I could do! I feel so much more confident in my body the more I work with her because I feel strong and capable. Erin is simply the best."

Sarah S.
"I’ve been going to Erin‘s classes for the last few weeks and have felt an amazing change! Just the fact that I feel like I can take on the world after, and have begun to feel more confident about myself is more than enough! I can’t wait to see the transformation that I know it’s gonna take place in my body in mind! Erin is so sweet, patient, and knowledgeable! Everything that you could look for a coach"
