Boston – Kaplan Construction announced the completion of work for a new obstacle training studio for Action Athletics. The facility, located at 42 Guest Street within Boston Landing’s Auerbach Center, marks the Wellesley-based company’s third location and the first of its kind in Boston.
“Action Athletics is one of the first and oldest dedicated ninja obstacle training facilities in the country,” said Nate Brosey, founder and co-owner of Action Athletics. “When we decided to build a new location in the vibrant neighborhood of Boston Landing, we knew we needed an experienced construction team who would be able to adapt to our unique design. Kaplan helped us deftly navigate the challenges of bringing our premium ninja experience to the community.”
Designed by Arrowstreet of Boston, the 4,000sf facility features a collection of authentic Ninja Warrior-style obstacles including the Warped Wall and Salmon Ladder. The gym also includes areas for parkour, climbing, and strength training. Additionally, Kaplan built a reception area, staff offices, and accessible bathrooms with showers. To achieve an industrial feel, the walls were finished with a mix of brick, metal panels, and oriented strand board (OSB) panels.
The space also received new mechanical, electrical, plumbing, and fire protection (MEP/FP) systems. Due to limited space on the roof for mechanical units, Kaplan installed the air handler above the offices and between the custom light fixtures. The installation, done out of sequence due to long lead times, required careful maneuvering to bypass the finished lighting.
The project team members also include New Balance Development Group, developer; Breen & Sullivan Mechanical Services, mechanical; Platinum Electrical Services, electrical; Lynco Fire Protection, fire protection; J.P. Campbell, plumbing; Wick Fisher White, MEP/FP engineer; and Stage 4 Designs, obstacle equipment/installation.
Action Athletics is currently open and offers daily classes, private lessons, personal training, and open gym time.
