Press, Curl, Row, And Swing

One Set Does It All

Less clutter. More lifting. The TriForm is three tools in one. A single set of plates becomes a dumbbell, a barbell, or a kettlebell. Dial in your weight, hear the click, and lift.

Turning the dial selects your load and locks it with a click, so every plate you're not using stays behind in the rack. Grab the handle, feel it engage, and lift with confidence.

When you finish, everything returns to its rack. No stray weights, no wasted room, just your full strength routine tucked into one corner.

So easy to use

"Love how easy to adjust and use this is and takes up less space than a whole weight set. Just wish you could set it up to be used as two dumbbells without having to buy a whole other set"
