DIY kettlebell.

DIY kettlebell handle. Materials: PVC and rope, tie down straps, or bungee cords. An inexpensive alternative to expensive kettlebells. This handle can be adjusted quickly to fit just about any dumbbell.

I used 1.5″ PVC for strength in my proof of concept, but I think 1″ PVC might be strong enough and the thinner handle would fit your grip and the dumbbell even better.  Let me know what you think.  I used rope and tied a hitch knot to slide and tighten to the bell with a figure eight knot for a stopper.

Materials:

3X @4″ lengths of 1.5″ PVC

2X 1.5″ 90 degree PVC elbows

PVC primer and cement

@8′ feet of rope.  ( the same length tie down strap or bungee cord might even work better )

dumbbell of your choice
