Orbit® 4" Muscle Therapy Ball

Created by a physical therapist, the Orbit targets the psoas, piriformis, and deep hip rotators - muscles that, when tight, drive low back pain, sciatica, and restricted hip mobility. These muscles sit deep in the hip and glute complex, and they need broad, sustained pressure to release, not the pinpoint contact of a small ball, and not the unfocused spread of a foam roller.

The Orbit’s 4-inch diameter and firm-yet-yielding density hit the precise middle: broad enough to cover the full muscle belly, firm enough to sustain meaningful pressure throughout the release.

Where the Hip Hook targets with precision, the Orbit prepares and broadens, making it both a warm-up for deeper work and a standalone release for the glute complex.
