Train in Lower Haight
Report
Our Lower Haight gym is our original location. It is a smaller neighborhood facility for those wanting a more intimate fitness experience. AJ has a bachelor's degree in kinesiology, which gives his approach to fitness an emphasis on human movement and exercise science. His belief is that the human body is a unique machine capable of adapting to whatever challenges are presented, particularly during workouts.
3D Body Scan

Whether you train on your own or with a trainer, it's important to know if you are making real progress toward the goals you are working so hard to achieve. We recommend taking measurements every 2 to 4 weeks to spot any trends that will help you make the necessary changes to keep yourself on track.
