I started at KG Strong roughly three months ago after more than a year a half of lockdown and sedentary living. Going into my first day, I was looking to shed the pandemic pounds and kickstart a healthy lifestyle, and after my first class with Meghan, I was hooked! Not only did I have a great workout with superb coaching, I felt welcomed to the class and didn't feel that the room was dominated by any "alpha" personalities that tend to be present at CrossFit and other types of gyms. I bought a 21-day pass and started coming 2-3 times a week, mainly to Elaine and Taja's classes. I love that each

The Strong Mom Strength Series is exactly what I didn't know I needed, and in so many ways. As a first-time mom about 3.5 months postpartum, I didn't know where to start with "getting back in the saddle" with exercise. All I knew is that I didn't feel comfortable going right back to what I was used to doing in terms of exercise before growing and birthing a tiny human. Katie has put together an amazing program that has made me feel stronger and more comfortable in my body; moreover, I have loved interacting with the other moms. Getting stronger in such a supportive environment has helped me beyond

Friends have been raving about KG Strong for years, so Katie and her company have been on my radar for some time. The Strong Mom Series was an excellent way to begin to feel more like myself after the birth of my baby. I'm a dancer who hasn't danced in quite some time, and I needed some accountability for starting to incorporate exercise back into my life. It felt so great to connect with my body in this new way, and to connect with other new parents who are doing the same. The semi-private structure allowed for a lot of attentive instruction. Highly recommend!

When I first heard about the Strong Mom Strength Series, I knew it was something I wanted to try. I was about 5 months postpartum and felt like a stranger in my own body. After 8 sessions with Katie, I'm starting to feel like myself again. My core and legs are noticeably stronger, I have less neck and shoulder pain and stiffness, and I feel motivated to continue building my strength and mobility. I highly, highly recommend this program!

The culture and environment at KG Strong are very warm and welcoming, and I have felt this way from my very first e-mail sent to Katie asking about the classes and prices, to each day I walk into the gym. Specifically, I had e-mailed Katie at least a month or two before I showed up for my first assessment and she remembered me. That personal touch and attention to each client is very important to me.
I started coming to KG Strong after I had healed from a broken ankle. My stability was not good, my hips were sore, and my leg muscles were very tight from wearing a boot on my right leg for two months

All the trainers are amazing. Caring people, really putting their heart into their work. The space is great, sunny and spacious. Equipment is spot on, everything you need no matter your level. I’ve been going for nearly two years, new clients come in and pick things up quickly, some folks are at real mastery level, could get StrongFirst certified themselves. Trainers work out here, beginners work out here, all are welcome and pushed to do better.
I’ve been coming for nearly two years, having worked out with Katie in 1:1 sessions and moving into small groups. I live in Fairmount, so I don’t

As a lifelong runner (and one whom suffers from back injuries), I have never felt comfortable in any weight training group. I jumped around from class to class but struggled to find a place that I felt was there to help me with my own goals (become a strong better runner) and didn’t just push me into picking up the heaviest thing I could at any cost. I have been with the KG strong group for six months now and I cannot believe I am saying that I look forward to my kettle bell classes! After the first few classes with trainer Anna Claire, I felt completely at ease and knew she was there to help

Katie Gould is an amazing instructor and trainer. She walks the talk, and is an inspirational role model for fitness, strength, and general healthy eating and living. I have been working with Katie, both in her classes at ZAKTi and one-on-one, for over a year and can say with certainty she is one of the best trainers I've ever worked with. I am working hard, getting stronger and fitter, and with Katie's guidance, doing it all with proper and healthy form. I couldn't recommend her more strongly.

Katie is an awesome yoga teacher! She brings her knowledge of alignment and an intuitive sense of what people need to her work, so her classes are tailored to each of her students. She pushes me to ask more of myself and has helped me to get to know how my body moves and what adjustments to make in order to really feel strong, flexible, and aligned.

To do the body good, one goes to Katie Gould.
I have the immense pleasure of working with Katie in her yoga class and, previously, under private fitness instruction. As an instructor, she finds a line between abstract or metaphorical thinking (particularly for yoga) and hard physiological fact, which leaves the student with better flow and a keener understanding of alignment and core function. In particular, I appreciate her on-the-fly anatomy lessons during yoga because I think in more black-and-white terms and can more effectively expand my kinesthetic awareness. Her yoga practice energizes
