Product Description
The Ultimate Core Crusher - Professional 3.1kg Ultra-Heavyweight Magnetic Hoop for Intense Calorie Burning
The Star Sports S-Rose Hoop 3.1kg EA3001 is the heaviest flagship model in the S-Rose series, specifically engineered for professional-level core training and maximum fat loss. Proudly Made in Korea, this 3.1kg ultra-heavyweight hoop provides immense centrifugal force, requiring significant core engagement to maintain rotation, which leads to unparalleled abdominal toning and calorie expenditure. It features Star’s signature magnetic air-cushion protrusions that deliver an intensive deep-tissue massage and acupressure effect, helping to stimulate internal organs and improve metabolic rates. Despite its massive weight, the one-touch 8-section assembly ensures it remains portable and easy to store. Built with a reinforced steel core and premium PVC/PE materials, the EA3001 offers the most powerful workout for those who have mastered standard weighted hoops.
