Aikido is an excellent martial art to cross-train in.
Whether you're into activities where it's all about you...yoga, ballet, pilates, gym workouts, cross-fit, circut training or team sports like soccer, netball, basketball, rugby and AFL, then Aikido can help you improve those activities.
Aikido, besides being an effective martial art where you actually learn to defend yourself, is about movement and balance and posture.
