Tennis

Singles or doubles on court, played as a lifelong sport rather than a workout

Racket sport played over a net, one on one or in pairs, in sets that can run past an hour. It mixes short sprints and lateral movement with long stretches of standing and thinking, which is why players describe it as both conditioning and a mental game. Regular players book a weekly match, hit with a coach, or drill serves alone. A public court costs little, and rackets and balls last for years; lessons and club memberships are where the money goes. Many people play into their seventies and beyond, usually switching to doubles.
