Slider with Convex Reversible Dome

Dare to defy gravity—this reversible convex dome amps up instability for next-level core firepower. Flip it, roll it, own every wobble.

• Convex profile raises the stakes for planks, knee tucks, or single-leg balances—goodbye autopilot
• Quick-flip design offers two unique balance surfaces in one compact accessory
• Matte rubber texture feels steady under palms or soles so you can focus on form, not slips
