StrongBoard Balance Board
Here are some levitators in training. Really. No, not really. I think they're actually people who really like to train in training, and upping their training game with the StrongBoard Balance.
I'm sure you've seen balance boards before, but StrongBoard says it will balance all of them off their spindles and rockers with its compression spring center. A pair of 18" x 26" platforms sandwiches 4 tightly-grouped springs to activate your stabilizing core muscles and encourage mind-body syncing during exercise. The StrongBoard Balance also enhances body weight resistance, making basic exercises such as squats or push-ups more challenging, and more effective.
StrongBoard Balance feels it has as much of a place in rehab and prevention as it does in resistance training. The company encourages physical therapists and fitness professionals to incorporate its balance, core strength, agility, and posture improvement capabilities in their prescribed patient treatment and recovery regimens.
They also encourage working-out-is-my-heroin addicts to try StrongBoard boxing, StrongBoard batting, and StrongBoard trying to run away while on a stretchy leash held by an out-for-blood-looking giant.
