The self-proclaimed "King" decided to up the intensity of this workout. Instead of using the blade, Lebron tried his luck with balancing not one, not two, not three, but FOUR kettlebells.
And while there's no doubt that this move is extremely tough, we were curious what balancing on a physio ball while waving around a weird metal implement (or balancing kettlebells) would do for us mere mortals.
"This move is designed to focus on proprioception—spacial awareness and deep core stabilization," Powell says. "The center of movement originates in the core, then extends outward to the 'sling systems' (arms and legs) to run, jump, and shoot. LeBron is doing this exercise because it is training his core to react to an unstable environment and fire rapidly—so when he puts himself on the court, he can react quickly to any unstable environment and deliver a peak performance."
As difficult as this may look, Powell says you can also try this move at home—you don't even need a Body Blade. First, Powell says, create instability by standing on a balance board, balance disc, or even just one foot. Then, you'll want to "deliver a dynamic upper-body stimulus." There are a few ways to do this:
Do arm circles
Swing your body side-to-side
Pass a kettlebell clockwise around your body, and then pass it counter-clockwise around your body
Grasp a single dumbbell with both hands, and extend it forward, to the right, and to the left
For example, Powell says, "a great way to do this at home would be to stand on one leg and perform arm circles or dumbbell ‘clocks’—extending a dumbbell in different directions like you are placing the dumbbell on different numbers on the face of a clock."
We're not saying it'll turn you into a superstar athlete overnight—but it'll go a long way toward improving your core strength and reaction time.
