j+k fitness studio

Been working out here for 6 months now and Griffin is the best trainer I've ever worked with...he's excellent at tailoring workouts to your capabilities (e.g. if you're nursing an acute or chronic injury he works around it while getting the right stimulus). He's also incredibly innovative in his exercise/movement selection. The gym is clean, has everything needed for training sessions, and I'm lucky to have found them!

Best personal training you could get in SF hands down. Jae and his team offer a top notch studio with all the gear and equipment you would expect: squat racks, great weights, rogue bikes, boxing bags, etc. The trainers also offer a range of programs designed for your goals. Griff is hyper focused on mobility so that you are able to build up strength safely without getting hurt. Christina is a pro at powerlifting or olympic weightlifting training. I came in at 175 lbs and 30% body fat and am now closing 160 Ibs and 20% body fat! Very happy to have found this nugget in the mission.

Training at J+K Fitness has been such a wonderful experience - Ive been working with Francisco virtually for several months and have seen a big improvement in not just my physique but overall quality of life. Its been super helpful to have both a place to train and the option for virtual sessions, as Im often traveling out of town and the flexibility helps to me on track. The studio is equipped with top notch machines and all of the trainers are super friendly and helpful! Definitely recommend this place if youre looking for a personal trainer.

Great trainers! I worked with a couple of different trainers for about 6 months. They helped me correct some muscle imbalances, build strength, and set a strong fitness foundation that I can build on. Incredibly knowledgeable and intentional. Would recommend and would go again.

I've been training with Benny since January, and shes fantastic! I've been consistently losing weight and have noticeable strength gains. I love her approach to training, and Ive been introduced to creative exercises I wasn't even aware of. The gym facility is great, and I plan to continue working toward my goals here!
