The average height and weight for a jockey is 5.4 feet (1.65 m) and 54-58 kg (119-127 lbs). Jockeys are among the lightest athletes in any sport, with an ideal body composition of 10%-12% body fat in order to maintain the optimal racing weight. This requires strength training, nutrition monitoring and careful race preparation to ensure that jockeys stay lean while being strong enough to control their mounts during a race. It also takes discipline not to gain too much muscle mass or be tempted by unhealthy snacks! The combination of skill, fitness and dedication required makes horse racing one of the most challenging sports around – but when done right it can be incredibly rewarding experience both mentally and physically.
