My favorite powerlifting gym of all time!! Visited this gym days before a USAPL meet this weekend and owner Kelley and meet director Leandro were so kind and so supportive! The gym is a lot bigger than I was expecting the equipment in the gym was amazing, there were so many different machines, and combo racks! If I lived in San Diego I would 1000% become a member at STS! Everyone in the gym was so nice and helpful and there was such an amazing vibe. Loved it here!


A premier powerlifting gym. Clean, kind, good vibes, focused individuals abound. Convenient location, showers and sauna/cold plunge if you are into that. 10/10 would recommend. Tell them I sent ya.


Absolutely the best gym in San Diego.Owner is responsive & friendly, gym is clean, and most importantly, they have everything you need to keep your performance to competition specifications. Calibrated Kilo Plates, Ohio Power Bars, Combo Racks, Deadlift Bars, and Squat Bars.

Even if it weren't for the special equipment which is all brand new and/or well maintained, the facility which is clean, spacious and has awesome lighting for 💪, or the fact that you'll almost never have to wait for a rack to hit squats, this place will more than suit your needs.This gym is packed with strong folks who gladly take the time to help each other get stronger, stay safe, and be motivated.


a1 facility with an a1 owner. 100% the place to go if you are training for any type of strength sport or you are looking to enter that atmosphere. Kelley and his staff take good care of their gym and their members!


12 years of training this one of the best gyms I've trained at. This is the gym to join if you in need of every specific equipment you need for powerlifting or any strength training. They have their own recovery station that pretty much most us are need.


Great facility and it is still growing. Have everything you could want, including pieces of equipment that are rare to find. Plenty of combo racks, power racks, bars, and platforms. Whether you are powerlifter, body builder, or strong man you can definitely put the work in here.Notable equipment thats not common in strngth gyms:Nordic BenchMono liftShowerSaunaCold Recovery TubThe staff is all friendly, and the crew that lifts there are extremely friendly and motivating. STS is the vibe you probably are looking for.


I have known Kelly for going on 10 years I was seeing him for some knee and shoulder issue. I have been following his growth and when he opened up his own gym I had to make the move. After being a sloth for the last few years it was time to do something about it. This facility has all the equipment you can dream of and the staff and members are very friendly and helpful. With Kelly insight in to movement you are getting quality coaching with an eye on injury prevention.Everyone here is focused on getting better at all levels. If you are looking for strength training or a gym that provides quit a unique set of equipment to meet your desired physical goals this is the gym for you.


Best strength training gym in San Diego, wide range of top of the line equipment, awesome facility, and knowledgeable and wonderful staff members. Some of the strongest lifters in San Diego train at the gym so the members and staff have an incredible amount of knowledge and experience.


State of the art gym with everything you could ever want or of the line powerlifting, olympic lifting, body building, and HIIT equipment. It's like Rogue & Kabuki Strength decided to have a child and it grew up to become STS …
