For those above normally strong, strength athletes, these heavy-duty, sand-filled med balls from Perform Better take your strongman training to the next level. While most medicine balls top out around 30 pounds, PBs matches that and then goes beyond, with 30-100 pounds available in ten-pound increments.

“I’m a huge fan of these medicine balls because of the variety they bring,” says Don Saladino, who has used med balls in his own training, as well as that of his clients like Ryan Reynolds. “I have been using med balls for years, and being able to go heavy and push my capacity is huge.”

Made from sturdy and durable PVC and filled with sand, these balls feel like gel, while the soft textured shell is easy enough to toss and catch (using the reasonably weighted ones). Whether you use them as Atlas stone pick-ups, over-the-shoulder pickup and drops, or keg tosses, you won’t find a better, heavier medicine ball.
