Optimus Strength is a 5000+ square foot facility located right off of south Ih-35. We offer group fitness classes, 1:1 training, nutritional coaching, and specialty programs for all fitness levels. Our community prides itself on being the most supportive and inclusive in Austin, TX! Optimus Strength was founded on the idea that everyone should have a place to call home.

The large amount of space isn't all Optimus Strength has to offer, we also have ample parking for all gym attendees. Our retail and lounge area house a couch, coffee pot, and mini fridge. Our retail selection consists of protein, pre-workout, Fitaid recovery beverages, water, and complimentary ice pops for those excruciatingly hot Austin summer days!
Services
Our Community Fitness program focuses on functional movement, strength, skill, and speed training. This full blown group workout is great for those with a little bit of previous workout experience! During class, our trainers will take you through a dynamic warmup, strength or skill work, and a "workout of the day".

Amazing gym. Justin and Cassie really care about their clients and it shows. It’s a great community and caters to all levels of clients, while also gently pushing you to challenge yourself.

Justin and Cassie have created a truly welcoming gym, where everyone can work on their own individual goals while being part of a larger, supportive community. I had been to other CrossFit gyms in the past and they felt too exclusive and sterile. This feels like a family, and everyone I work out with has been kind, encouraging, and fun. I have seen fantastic progress in my strength and mobility since I started months ago, and I'm really happy with the emphasis on form and safety so that I can keep making strides consistently, without injury. I love it here!

Optimus has been a great experience. I really appreciate how much time we spend stretching and preparing our body for the workout. The programming isn't random but specific to a cycle. It's a great place to become the best version of yourself!

I've been going to Optimus now for almost 2 months. Justin and Cassie have been great instructors and coaches. I've never done group workouts or consistent resistance training, and they have helped in every session help build up my abilities. Above the physical workout both show genuine interest in my goals in and out of the gym. They have created a wonderful sense of community that I'm happy to be a part of, as well as my dog who comes to most workouts. Every member I've met is also equally amazing and it's great to cheer and be cheered as we each push past our own limits.

Justin and Cassie are AMAZING!!! I have been going the past few months and coworkers and friends are already commenting that they can see a difference. They really set you up to succeed and meet your goals. The facility is constantly being cleaned and the group classes are very small. Everyone is so supportive and welcoming. I love it.

Optimus Strength is one of my favorite places in Austin! Love the trainers and members, everyone is friendly and professional. As a new Austinite, this gym gave me a sense of community with their hardcore workouts and fun events. I am very impressed with how clean and organized the gym is and how they ensure everyone is safe. But the thing that I love most about Optimus Strength is the fact that the owners (Justin Kerr and Cassie Edmiaston) really care about us, they make a concerted effort to ensure we are focusing on both our physical improvement and mental health. I highly recommend it!

Justin and Cassie are vastly knowledgeable beyond their years. Not only do they create amazing workouts, but they’re knowledge of nutrition and body maintenance are a major plus for me. I also admire the fact that they’re able to work with all “types” of people- the very skilled, intermediate, older, younger, and beginners. I also love the environment of the gym. You can really tell that Justin and Cassie are in this for the love of people, fitness, and nutrition. I highly recommend coming and checking them out, because once you do you’ll fall in love with them, the workouts, and all

My favorite gym in Austin! The coaches (Justin and Cassie) are super knowledgeable, friendly and supportive. They encourage you to always give your best in every workout and help you become a better athlete. I LOVE the community as well. It’s not just a place to sweat for an hour and go home, but meet like minded people who are interested in total well being. Definitely check this place out!
