Zoid 2-in-2-out works footwork and athleticism from the ground up
I always say, "athleticism works from the ground up!"
It all starts with your feet. How well your feet move and make contact with the ground determines how your body moves. I call it "clean footwork". The cleaner (more efficient) your footwork is, the more efficient your movements are.
I love using the SKLZ Agility Trainers for footwork. Keeping the athlete in one place, footwork can be trained using a variety of movement patterns.
A favorite of mine is "2-in-2-out". This is done by athletes keeping their body over the top of the Zoid as their feet move side to side. The movement is made "clean" by staying on your power pads (forefoot) and not scuffing or sliding your feet across, but by picking up your feet in small steps.
Although this is done in place, it will translate into how athletes move forward, backwards and laterally.
