10 Best Slam Balls 2025 in the United States

The Yes4All Fitness Slam Medicine Ball is a robust and versatile workout tool designed for various strength and power exercises. Weighing 30 pounds, it caters to those looking to enhance their fitness levels through intensive workouts. Its PVC outer material ensures durability, while the sand-filled core prevents the ball from bouncing or rolling, adding to workout safety and stability.

The ball's textured surface provides an excellent grip, reducing the likelihood of slips during exercises like overhead smashes or Russian twists. This slam ball maintains its shape well, even with consistent use, ensuring reliable performance over time. One potential downside is that its 30-pound weight might be too heavy for beginners or those new to strength training.

Additionally, its size (with a diameter of approximately 11.42 inches) could be cumbersome for smaller individuals. Nevertheless, the Yes4All Fitness Slam Medicine Ball is a solid choice for adults looking to challenge themselves with a durable and well-constructed exercise ball. It is particularly suited for those engaged in sports training, conditioning exercises, and general athletic training.

The Champion Sports RPX4 Rhino Promax Slam Ball weighs 4 pounds and has a diameter of 14 inches, making it a manageable size and weight for most adults. Its outer shell is made from a soft synthetic leather (faux leather), which provides a smooth yet non-slip grip thanks to the Rhino Skin texture. This grip helps you maintain control during exercises, even if your hands get sweaty. The ball is designed to offer a decent bounce with more give compared to traditional medicine balls, which helps protect your hands and wrists while slamming or throwing it. Its durable construction means it can handle repeated impacts and rough use on hard surfaces, though constant slamming from overhead may eventually wear it down and void any warranty.

This slam ball is well suited for full-body workouts, including plyometrics, CrossFit, weight training, and cardio, as it targets both major muscle groups and stabilizing muscles. The 4-pound weight is light enough for beginners and people focusing on speed and agility, but may be too light for those seeking heavier resistance. The ball’s 14-inch diameter provides a comfortable ergonomic size that is easy to catch and throw.

While its faux leather cover is durable, users seeking a very heavy or fully bounce-proof slam ball might look elsewhere. This slam ball provides a good balance of grip, size, and bounce for general fitness use and fits well for those wanting to add variety and dynamic movement to their workouts without complex equipment.

The Champion Sports RPX16 Rhino Promax Slam Ball is a 16-pound exercise ball designed for intense workouts such as weightlifting, plyometrics, and cross-training. It measures about 14 inches in diameter, providing a good size for gripping and throwing during full-body exercises. The outer shell is made from soft synthetic leather (faux leather), offering a smooth yet non-slip grip even when hands get sweaty, which helps maintain control throughout movements.

Unlike regular medicine balls, this slam ball is built to handle repeated slams without bouncing excessively, thanks to its durable rubber fill that absorbs impact well. This makes it ideal for exercises involving forcefully throwing the ball to the ground or wall. Frequent slamming on rough surfaces may reduce the ball's lifespan and void warranty coverage, and the softer synthetic leather might wear down faster than heavy-duty rubber balls with heavy outdoor use. It is well suited for adults seeking a reliable, mid-weight slam ball for home gyms or fitness classes, providing a full-body workout without the need for complicated equipment.
