  • Excellent device!

    I love being able to have different weights of kettlebells without the clutter in my basement. Plus, it's easy to attach and remove. Thanks for creating this!

  • Love these

    I purchased the hyperbell bundle. It has the straight bar, pad and kettlebell. I love these and the idea of these. Makes upright rows and other exercises so much easier. Easy to use and switch out weights. Have not used the pad for the bar yet but I'm sure it will come in handy when needed.

  • Steven Ang

    Dumbbells and kettlebells are great to workout. The Jayflex adds another dimension and gives you the ability to take your workouts to another level.

    Christine Alejandro

  • Solid built with flexibility in mind

    I purchased the straight bar with pad and the kettlebell. Quality is fantastic and is well built and easy to use. My home gym really needed these attachments to go with my bowflex 552 set of adjustable dumbells. Im ordering the new resistance band kit and the ez curl bar in the near future.

    Matt Morgan

  • Great workout

    I bought these just a month ago, they have worked great and just as promised. They had lead to really great workouts using my dumbbells as kettlebells!
