Description
One set, four ways to train. Use the plates as a pair of dumbbells, connect them into a barbell, attach the kettlebell handle for swings or flip them into push-up stands.
Change the weight in seconds by adding or removing plates, then lock them in place with the double nuts. The coated plates are quiet on the floor and won't scratch it.
- 4 training modes for curls, presses, rows, squats and swings.
- Foam-padded connecting rod for comfortable barbell work.
- Compact storage: the whole set fits on one shelf.
Perfect for couples and families who share a small home gym.

Huge space saver
Got rid of 6 pairs of old dumbbells. This does everything and fits under my desk.
Love the kettlebell mode
Didn't expect the kettlebell to feel this solid. Swings feel great.
Good set, takes time to swap
Changing between modes takes a minute or two, but that's the trade-off for saving space.
Me and my husband share it
He uses the barbell, I use the dumbbells. Quality is great for the price.
Plates stay tight
The double nuts actually work. No rattle at all during presses.
Great value
A bit of a rubber smell out of the box, gone after a few days. Very happy otherwise.
Questions? We have answers
How do I change the weight?
Unscrew the nut, slide plates on or off and screw it back on. It takes about 20 seconds per side.
Is 45 lb enough?
For most home workouts, yes. That's up to about 22 lb per dumbbell. Choose 66 lb if you already lift regularly.
Will it damage my floor?
The plates are coated, so they're quieter and softer than iron, but we still recommend a mat for heavy drops.
