From cross-discipline fitness. Equivalent to cross + fit. cross comes from Middle English cross. From Middle English cross, cros, from Old English cros (“rood, cross”), from Old Norse kross, from Old Irish cros, from Latin crux (crucī). In this sense displaced native Middle English rode, from Old English rōd (“cross”); see rood. a doublet of crouch and crux. Compare Welsh croes, Irish crois.
