EngineRM

Those looking to join any rowing class at this new Columbus Circle studio must first take Rowing 101, which teaches proper technique and commands. After that’s completed, rowers can sign up for a regular EngineRm, an indoor workout that focuses on group exercise. There’s no music in this 12-person class—instead rowers focus on the rhythm of the erg machines and the motivating commands from the coach. Each session is themed around a specific regatta, such as the U.K.’s Henley Royal and Boston’s Head of the Charles.
