What waist size does it fit?

This belt was carefully designed to be one size fits almost all. With the adjustable velcro strap it fits all waist sizes from 26-40.

How much weight does it hold?

We have tested it up to 500lbs without any issue. If you plan to use more weight, reach out to us and we can test it!

What excercises can I do with it?

The belt is mainly designed for muscle ups, pull-ups, and dips. However if you get creative you can also use it for pushups and squats. However the vest is better for these movements.

Should I get the belt or the weighted vest?

They are two very different equipment even though they both add weight to the body. The dip belt is ideal for pullups and dips, but the vest is better for all other exercises such as the squat, lunge, pushup, pike press, inverted row.

Furthermore, because the weight is distributed differently, doing a pullup will feel different with a vest and belt. This is very similar to the difference between a front and back squat.

Therefore, for optimal results we recommend you get both.

Duo Belt

fits well and able to carry a heavy load

Great dip and weight belt.

Fits my 30 inch waste perfectly, and the use of the cord is genius, I string it through the weight plate twice and it hangs at a perfect length. That would not be possible with chains. Another innovative product from Kensui!! Since getting much of their equipment I’ve taken my workout routine to heights I have not been able to achieve previously. I’m 60 and have never been stronger with much less back and hip pain.
