Slackblock

Slackblock

SlackBlock is a small, simple, but uniquely effective balance trainer that’s associated with the SlackBow training method. This patent-pending device is designed to emphasize one-foot balance training, an essential in all types of athletic balance. Few sports are played, after all, with weight equally distributed on both feet in a static position.

This is a phenomenal balance and proprioception tool in a very portable package. The upper and lower are Velcroed (suggesting each is replaceable), but not available for purchase separately. Time will tell how durable the foam lower is, but it has held up well. Please note there are 3 sizes available: 13" for people <190#, 14" for people 190# to 230#, and 15” for people 230# to 300#.
