ลูกบอลออกกำลังกาย ZELUS Dual-Grip Medicine Ball – น้ำหนัก 10/20 ปอนด์ สำหรับฝึกความแข็งแรงและแกนกลางลำตัว

The rubber really is odorless, which I didn't expect – most weighted balls have that chemical smell right out of the box. I've been using it for core circuits and the high-density feel gives me confidence it'll hold up to daily slams.

It’s got a nice firm feel that doesn’t bounce around, and the high-density rubber holds up well even after I’ve slammed it on the floor a few times. No smell at all right out of the box, which was a pleasant surprise. Perfect for my core circuit on days I don’t want to hit the gym.

The dual-grip design is a game-changer for core work, and the high-density rubber holds up well even after slamming it on concrete. I've had mine for a month now and it still feels as solid as day one, which is more than I can say for my old ball.
