Beach Volleyball

Played 2-on-2 on soft sand that reduces vertical jumps by 30% and turns every lateral move into a leg-burning squat, beach volleyball features no substitutions, "pancake" digs, and the "float serve" (a knuckleball with no spin) that becomes devastating in the wind. Matches are best-of-three to 21 points, open-hand "dinks" are illegal unless executed with a locked elbow, and the partnership is everything -- silent communication through hand signals behind the back, with diving saves and towering blocks in the sun.
