Grab a shuttlecock!
From jumps and lunges to smashes, drop shots and lobs, tennis and badminton are so similar they even use the same words. The main difference is that badminton is played on a shorter, narrower court with a higher net. The footwork and tactics are different but complementary. Let us explain:
An explosive sport! Badminton is an incessant series of jumps, adjustment steps, and lunges forwards or to the side. Your body has to constantly react to the shuttlecock's flight path. Your glutes, abs and back muscles are subjected to intense repetitions over very short periods of time. Applying this explosiveness to your tennis will increase your dynamism and your ability to react to your opponent's shot.
Coordination and flexibility! As a fast sport, badminton requires you to constantly shuffle your legs and adjust your movements/footwork based on the shuttlecock's trajectory. This develops not just your coordination, but your flexibility too. In tennis, these two criteria will make you much more precise and your new-found upper-body flexibility will accelerate your shots.
Fly like the shuttlecock! If you play badminton for an hour, you'll run on average 5 to 6 km. Your footwork is light and floaty. This is really beneficial for your tennis, particularly for your split step before hitting the ball. It's essential for good positioning.
Do you know where badminton comes from? Badminton originated in South East Asia, where a sport called "poona" was played with a light ball and a racket. In 1873, the British drew up the rules in the town of the same name (Badminton!), but because they didn't have a ball, they attached feathers to a champagne cork. The shuttlecock was born.
