A 20-part video series devoted to off-ice drills that the USA Hockey National Team Development Program uses to keep the skills of players progressing when they aren't on the ice, comes to a close with the 21st and final segment. Each drill, narrated by NTDP assistant coach Ken Martel, builds on the one prior, and "Balance Board," is the grand finale. It requires a pair of 2 x 4s, one stacked perpendicularly on the other while the player stickhandles on top.
