  • Here's What Our Athletes Have to Say

    "I just took a Tabata class from Susan, the owner. Woohoo! Tabata is wonderful for strength and cardio work through working different areas of the body instead of plain old running or spinning. It's a workout. Everyone can push themselves, challenge themselves no matter if you need to modify a little.

    Susan knows fitness. her place is stocked with equipment for different sets of Tabata and other fitness classes. This is easy to get to with street parking and a lovely window and area of Seattle to be in."

    "This place is the real deal. I went here for a class last November and I have been going 2x a week ever since. These classes are tough! High energy, fun, sweaty and kick-ass.  Susan is an incredible trainer and I cannot get enough of her workouts.  Each week is a different format to keep some variety.  I can truly say I feel stronger ever since starting to workout at the strength studio."

    “I have been working out with Susan since the beginning of covid.  I’ve never met Susan nor have I been in her studio. I live in southern Oregon and I do her workouts through Facebook.  I love the convenience of working out when I want to.  Workouts are different every time some days harder than others but no matter what Susan is encouraging “you do you!”  She makes me laugh out loud and push myself as hard as I can.  The ease of all the workouts on Facebook to go back to anytime and do again is an added bonus.  On a personal note, I’ve lost a solid ten pounds and feel stronger than ever!  Thank you Susan and hopefully someday I’ll get in your studio!”

  • Here's What Our Athletes Have to Say:

    I’ve been a dedicated member of Strength Studio for 15 years, and I can honestly say it has completely transformed both my physique and my attitude toward exercise. Working with Susan Slater, the head trainer, has been nothing short of life-changing. Her group classes, which are available both in-person and virtually, offer an incredible blend of energy, motivation, and structure, and they’ve kept me coming back year after year.

    What really sets Susan’s classes apart is her ability to make strength training and body sculpting both fun and challenging. She has an amazing way of making every workout feel unique, with a focus on building real strength while improving muscle tone and definition. No two classes are ever the same, which keeps things fresh and exciting. Her energy is contagious, and she has this special knack for pushing you to do more than you thought possible while always keeping the atmosphere supportive and motivating.

    One of the best things about Strength Studio is how much more confident and capable I feel in all aspects of my life. Whether I’m tackling a new workout, running errands, or simply carrying groceries, I notice a difference in how strong and capable I am. Susan’s training doesn’t just help me improve in the gym; it has an impact on everything I do outside of it.

    Strength Studio has truly been a cornerstone of my fitness journey, and Susan has been instrumental in making this experience so positive. If you’re looking for a workout that’s both fun and transformative, I can’t recommend her enough!
