A perfect complement to the original MobilityWOD Big BattleStar™ roller, this small spindle is half the diameter (50mm), allowing for more acute pressure—like a barbell with better grip and adhesion.

The Little BattleStar™ was developed by MobilityWOD founder and doctor of physical therapy, Kelly Starrett. His goal, as with the Big BattleStar, was to improve on the standard tube-shaped foam roller by designing a tool that could create a lot more shear in the joint tissues. The solution was to use a spindle with a row of 12 Urethane rubber discs, which produce a far better gripping action for an instantly noticeable effect.

The Little BattleStar™ is versatile, as well. You can use it independently on the ground as a basic roller, or use the BattleStar Cradle (sold separately) to elevate and hold the roller in position—giving you better leverage for targeted work on the hips and larger muscle groups.

As Kelly Starrett puts it, “If a steam roller, wolverine, and a chain saw got together and had a baby, the BattleStar™ would be born.”
