Rogue MK D-Balls - 14” Medicine Balls

Rogue’s MK D-Balls are oversized versions of our standard D-Ball medballs, with 11 different weight increments (from 14 LBS to 150 LBS) each measuring the same 14” in diameter. This increased width can create a welcome new challenge for athletes in both traditional medicine ball workouts as well as slams and wall ball target training. Like the original D-Balls, the MK model still has the sturdy feel of a gel-filled medicine ball with a textured rubberized shell—meaning it offers the same superior grip and durability.

All of our D-Ball Medicine Balls are manufactured in the USA and used in a wide range of disciplines, from CrossFit WODs to military training, rehab work, and the strength programs of major high school, college, and pro sports teams. Despite their rubberized exterior, they produce a consistent dead bounce when slammed, and because all MK D-Balls have the same diameter, athletes can benefit from consistency in feel and hand position as they move up to heavier weights.

D-Ball Medicine Ball training can produce similar strength and power training benefits to Olympic lifting. With the ball held off the centerline, it can be particularly advantageous for improving an athlete's range of motion, flexibility, and core strength. Key Features of Rogue MK D-Ball Medicine Balls

Slamball / Medball Versatility

MK D-Balls can be used for standard medicine ball training (medball push-ups, trunk twists, squats, sit-ups, presses, etc.) as well as movements not always recommended with traditional medballs, including overhead medicine ball slams and wall balls. The gel-filled feel of the D-Ball combines with a durable rubber shell and soft textured grip to produce a hybrid slamball / medball optimized for both speed and power. Because of the ball’s dead-bounce design, athletes can slam aggressively but still get the training benefit of picking the ball off the floor each time. Please Note: To protect your flooring and/or walls, slams with MK D-Balls may require use of a protective mat / pad.

One Super-Size, Many Weight Options

We offer a wide variety of weight increments for the MK D-Balls, but all 11 options share the same 14” diameter, maintaining a consistency in feel as you move up to higher weights. Ranging from just 14 LBS to as much as 150 LBS, there is an MK D-Ball for athletes of any size and skill level, as well as any type of medball or slamball movement (a 30LB slamball, for example, is one of the more common standards in many WODs).

Made in the USA

Rogue MK D-Balls are manufactured in America and extremely durable even through repeated daily slams, wall ball throws, etc. The rubberized exterior shell not only produces a consistent dead bounce, but includes a soft texture and grooves for superior grip. All D-Balls are backed by an exclusive warranty: 2 years for individual use and 1 year for commercial use.*

*Warranty against failure does not cover any ball which has been damaged due to negligent or faulty use, or alteration by the user. International customers will be responsible for replacement shipping. NOTE: Negligent use includes slamming of the ball on an abrasive surface. THIS WILL DAMAGE THE SHELL and is not covered under warranty. Please ensure the floor space being used features a smooth surface and is clear of debris.

    Rogue MK D-balls is rated 4.7 out of 5 by 22.
    Rated 5 out of 5 by from Great product great price I bought the 14 and 20 pound ball. They work great and have the right amount of bounce. Much better than the soft shelled balls I bought.

    Rated 2 out of 5 by from Deform with each drop Our club has owned many different slam balls, all trying different designs to make a ball that resists abuse. This rogue ball seems like it will but I may never find out as it a pain to slam. There is no air inside at all so the ball turns into an egg with each slam. When you slam it on an oblong side it bounces erratically making it harder to catch and when it slams into your ankle it feels terrible. It works ok for a stone replacement for its firmness but as I said when it deforms our females have said it makes for a rather uncomfortable pick up compared to a normal stone. I would say the balls are probably fine if you know what to expect but thus would not be the ball I would purchase to meet our expectations

    Rated 5 out of 5 by from Perfect ball Just got it and it's a great added ball to my collection. Slam it down and it bounces below the knees, but yet, perfect to keep momentum going, not too low, not too high. Good for cardio. The 14ins is perfect for ball handling.. A must have for your arsenal, believe me!

    Rated 5 out of 5 by from Bang for the buck! These balls are some of my favorite "toys". Having such a range of weight, but all the same size, makes these usable by pretty much everyone. The range of things that can be done with these is huge, just requires a bit of creativity. And, in these difficult times, they make great backyard/garage workout tools. The only slight downside is as you get stronger, they get pricy particularly with shipping. But still, great value overall. Highly recommend!

    Rated 5 out of 5 by from Work and Fun The 50 and 70 pound D ball work has given my coach a number of new workout options. I have enjoyed working with them while doing Crossfit over the last 10 years. These D-Balls made in the States are durable and ready to be thrown around. If you are building out a home gym or just getting a few items to do some work outside the D-Ball because you can't get in the Box is a fun addition that provides a number of options.

    Rated 5 out of 5 by from Heavy slam ball It’s a big heavy ball that you can throw over your shoulder, run with, clean and press, and slam. The rubber has great grip, which is great on your hands, less great on bare forearms. Or your face. I bought it for shouldering and carries so the Rogue 100lb sandbag would have been a better option (shipping is better on an empty canvas bag as well) but I hope to be doing slams with this at point

    Rated 4 out of 5 by from Everything I was looking for in a slam ball So far this slam ball, has met and exceeded all of my expectations. I’ve only just begun to use the ball. So now let’s see how it withstands it’s use. The outer layer is made out of a extra thick rubbery vinyl, and the core contains a sandlike mixture. NO BOUNCE !!! only gave it 4stars, the rating should go higher, only time will tell. Looking for a great product, this is it.
