It really depends on how you define “hard.” Physically, sports like rugby rank high due to the demands of endurance, tackling, and speed. Mentally, sports like gymnastics or netball require focus, timing, and strategy. Whatever your measure, the toughest sports are the ones that push you in more than one dimension. At rugby in Singapore players can dive into both rugby and netball, each offering its own version of difficulty and growth. In the end, the hardest sport is often the one that teaches you the most—and both rugby and netball do just that.
