Stay Motivated

Surround yourself with likeminded individuals all progressing toward their goals, while experiencing the benefit and creativity of an excellent trainer.

Stay Accountable

People tend to work harder in the presence of others, especially others we like! Our clients are really cool people, and often find themselves coordinating sessions together.

Stay Injury-Free

Whether you need sport-specific training, work-arounds for injuries, you are training with a medical condition, or just want to age gracefully, small group can get you there.

Plus, our programs fuse together to give you the most well-rounded workout in the Bay. Whether you’re looking to transform your body with personal training and nutrition coaching, achieve success in small group, or maintain fitness as a lifestyle in our group classes, we’ve got it in one place. Get ready to flex your limits and reach your fitness goals.

Small Group Sessions


The foundation class of small group. Your trainer will work with you with plenty of hands on assistance during the session of weighted and bodyweight movements. Your focus for the day will be either:

Core- focus on the muscles of the core, the abdominals, obliques, and transverse

Pull- focus on the pulling muscles of the upper body, the back and biceps

Push- focus on the pushing muscles of the upper body, the chest, triceps and shoulders

Legs- focus on the muscles of the legs, the quadriceps, glutes, hamstrings, and calves

TRX Riptrainer

We’ll strengthen the core like never before using the TRX Riptrainer, an innovative weighted bar and resistance bungee duo.

This piece of premium equipment makes every exercise a core exercise, and utilizes more muscles of the core than most other gym exercises. We do full-body exercises like lunge press-outs, overhead squats, and more, making this a great class for those who can’t get enough core work!


Aerial Hammock

This class extends beyond just aerial yoga in a hammock. We’ll learn to use the aerial hammock as an apparatus to find flow and fluidity.

Please do not wear clothing with zippers or anything that could potentially snag the hammock material. Jewelry (especially rings) may not be worn during class.

Please wear leggings or workout pants that cover the backs of your knees. Participants should also wear a shirt that covers their underarms, and grippy socks.
