Train your explosive power and improve conditioning with REP’s Slam Balls. These weighted balls are super durable, made with a double-thick shell and reinforced air valve so you can slam them against the floor thousands of times without worrying about them breaking. Their grippy shell offers just the right amount of texture to ensure a solid grip on the ball during even the toughest workouts. 

Slam balls are made from thick rubber and filled with sand, and they have a soft, shifting feel. REP Slam Balls are made in 12 different sizes, from 5lbs all the way to 70lbs, to accommodate a wide range of strength and fitness levels, even children. Diameters vary by weight, too, starting at 9-10” for balls up to 30lbs; 11-12” for balls 35-50lbs; and 13-14” for the 60-70lbs balls. Slam balls come with a full, one-year warranty for home use and six months for commercial use.

  • What size of slam ball should I use?

    This depends on your strength and ability level, but generally we see women using the 10lb to 25lb range and men using the 20lb to 40lb range. Kids and beginners do great with a 10lb slam ball.

  • What’s the difference between a slam ball and a medicine ball?

    Slam balls are made from thick rubber, filled with sand, and have an air valve that releases pressure to prevent bursting. They are meant to be slammed thousands of times without breaking and generally have a soft, shifting feel. Medicine balls are typically handmade using stitching and a variety of external shells, like leather or synthetic materials. They are designed for training dynamic movements such as throwing, not slamming.

  • Do the slam balls have a warranty?

    REP Slam Balls come with a full, one-year warranty for home use and six months for commercial use. Like a tire on a car, slam balls are a consumable good and will occasionally need to be replaced. Use slam balls on a smooth, debris-free surface to ensure a long life span.
