Any Recommendations on how to make your own Dynamax Medicine Ball?

I just made a 20lbs medicine ball with an old rubber basketball and sand. Turned out far better than i expected. (Rubber shoe glue worked wonders). Its great for ball slams and wall ball but now I want a Dynamax type ball. I would always use a Dynamax ball at my globogym for Thrusters. Now it just feels weird doing them with out it.

Any of you CrossFitters ever make one or know how to?

Don't know if this will help, but I've heard that you can wrap the basketball with cotton batting for quilts, and duct tape the heck out of it. Let me know what you figure out, or if this works.

Re: Any Recommendations on how to make your own Dynamax Medicine Ball?

I used about 2 cotton pillows. I pulled the cotton out, and wrapped around, then duct taped. Don't be discouraged at first, just keep wrapping the entire ball, then add more cotton and do again. Keep adding cotton and duct taping till you get 14" in diameter.

Here is a pict.

Re: Any Recommendations on how to make your own Dynamax Medicine Ball?

I just bought a ball yesterday(I will have to check the kind again) it is a synthetic rapped ball I am not sure on the diameter but it is a 20 lbs ball and it was like 46 shipped or something like that. i will look at my email and get the details and post after I receive it so I can give feedback on it. I ordered it last 2 nights ago and I was kinda spaced when I did it.(I usually buy stuff when I end up in this state ) So I will keep you posted.

Hey Bronson

You won't need to fill the ball up entirely. I used a smaller size basketball and filled it up 3/4. After I sealed the slit with layers of rubber shoe glue I pumped the ball with air to give it a round shape. It all depends on the sand you use too, so just have a scale near by and just keep weighing it.
