Most training moves forward and backward. Lateral movement is where athletes are built — and where most people are weakest.
The slide board forces your body to work in the frontal plane. Glutes, hip abductors, inner thighs, and the stabilizers that hold your knees in line all have to engage. Speed skaters use it. Hockey players use it. Rehab protocols use it.

Smooth surface. Included booties. Sets up in a hallway. Train what most athletes skip.
