The Yonex Muscle Power 40 Green Dot Tennis Balls (60 Balls) are stage-1 training balls designed to help young players develop fundamental skills with confidence. These balls travel approximately 25 % slower than standard ITF-approved tennis balls, making rallies easier to sustain and giving learners more time to react and position themselves on court.
Part of Yonex’s progressive junior training system, Muscle Power 40 balls are ideal for school programs, coaching sessions, and junior practice drills, helping players build timing, stroke mechanics, and court awareness on full-court or reduced-court settings. Supplied in a bucket with 60 balls, this pack offers excellent value for frequent practice and group coaching.
The bright Green Dot marking enhances visibility, helping players track flight and bounce, while the durable felt construction ensures consistent playability through repeated impacts.
