      Three Hammers is a welcoming, supportive and inclusive training community conveniently located on 63rd street right off of Roosevelt Avenue in Woodside, NY. We are a block from both the 61st street 7 train stop and LIRR Woodside stop.

      Our facility is equipped with barbells, weightlifting platforms, kettlebells, dumbbells, a Rogue pull up rig, Concept2 rowers, bike-ergs, ski-ergs and much more. We train anyone and everyone. You’ll find students, executives, stay-at-home parents, athletes, artists, first responders, educators, lawyers, and more. All fitness levels are welcome!

      Through our years of experience coaching and leading, we've learned that "movement is medicine". We all come from different walks of life but in this gym space we're all faced with the same adversity. If we teach our clients how to move properly and then add intensity, they can achieve levels of fitness they previously believed impossible. Our experience has also shown a warm, welcoming and caring gym community is crucial to our clients achieving their fitness goals. Its a game changer when you're excited to walk through the gym doors each day and we strive to make that possible for all of our clients.
