This med ball is excellent for fitting out negative, angry vibes AND getting in the best shape of your life.... Made by Century, this weighted 10lb medicine ball is filled with sand. Slam to the ground for a killer abdominal & back workout and enjoy it smashing without the danger of bounce. Without a pocket of air inside, this weighted ball (a little bit smaller than a volleyball) can be used to curl, squat and press like any weight......it's excellent to put in a backpack to do weighted pull-ups too Clean but with some general discoloration the ball is in perfect shape. 10lb weight Stored in a constant temp area, no dry splitting of any sort Smoke/ pet free environment
