CrossFit Viertel Zwei in Vienna's 2nd district offers CrossFit training across 300 square meters, featuring barbells, kettlebells, pull-up bars, medicine balls, and rowing/ski/bike ergometers. The gym provides daily group classes including HYROX training, yoga, endurance, and strength sessions, plus 16 hours of open gym access daily. It suits everyone from complete beginners to experienced athletes, with access to the adjacent 6-square-kilometer Grüner Prater park for outdoor training.
CrossFit Viertel Zwei 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 SkiErgs and rowing machines — the kit that matters most for practising HYROX stations at competition standard.
