The Handle Bar – Back Bay offers HYROX-specific classes, so you can train the race's running-plus-stations format with coaching rather than piecing sessions together yourself. For race-specific work, the gym has a sled track, SkiErgs and rowing machines — the kit that matters most for practising sled push and pull efforts at competition standard.
