NOYA Engage Ball

It makes the core honest. Between the knees in a bridge or under the lower back in a curl-up, the ball shows where the body cheats.

Support or wobble, your choice. Half-inflated it cushions the sacrum or the neck; fully inflated it moves under a hand or a foot and the stabilisers switch on.

20 cm is the size. Between the knees, under the pelvis, behind the back. A big gym ball does none of these.

Keeps its shape. Airtight valve, high-density PVC, matte non-slip skin. Pump in the box.

If you want a ball to sit on or to squat against a wall, that's a 55–65 cm ball. The Engage Ball is for mat work.
