JFIT Plyometric Boxes - Made in Taiwan NO Assembly Required Single - Height Box Set and Adjustable Box Options Plyometric Platform and Jumping Agility Box for Training Conditioning Strength Training

Wow, the construction of this box is amazing. It’s ultra strong. It looks beautiful. The craftsmanship is five star, that’s exactly what I was looking for, I just love it.

Got this set for my boys to train with during their offseason. Just another addition to my growing home gym. It has been used a few times already. No issues with the quality. The paint on them is very good. The box this came in was bulky and heavy and took a beating from the shipper. When I Opened the box up all four jump boxes were fine and not damaged, not even a chip on the paint. I was pretty surprised about that. The wood they used for the top of the box appears to be good quality plywood. The construction is solid and square. The one and only thing I saw that could be improved upon was the rubber top. It feels a lil slick like a vinyl but it does have groves in it for grip. Not really even a complaint plus I got a great price on the set. Ill see how long these hold up after my boys start abusing them.

My JFIT Box is absolutely perfect. It's sturdy, well constructed, beautiful and I know it will last forever. I plan on using it for exercise but I can also see it doubling as step stool whenever i need to an extra 12' taller. Well done JFIT. I am a happy customer.

I purchased the J/Fit adjustable PLYO box (12"/16"/20") and it is perfect for my workout room at home. I can do one-legged lift ups and bulgarian squats among many other excercises. It doesn't take up much space. It came assembled at 12" height and is easy to adjust and very stable. Highly recommed this product.

This product came assembled and packed really well. It is a decent weight while still being easy to move. Very sturdy and stable and the top is non slip. I would 100% recommend it.

I'm not expecting a gym-quality piece for stadium climbs or massive free weights. Just a solid device for safe concentric and eccentric leg development at home. This will do very nicely, even if I fail to keep the cat's claws off the vinyl top covering! Good welds and powder coat on the steel frame, with thumbscrew sets for the typical rod-and-hole style height adjustment. The plastic feet are lightly glued onto the square metal legs, so they'll need to be better secured if moving around much is expected. The lowest actual height on this 12-16-20 adjustable version is 11 3/4 inches, and the higher positions are similarly short of nominal. Not a problem for me at all, since the whole thing rests flat, level, and quiet -- even on a ceramic tile floor. That's especially important to me, since I 'll be focusing on the step-down part even more than the opposite motion! Finally, I don't forsee any construction issues if I use this with 25 lb dumbbells, as planned.

This thing is very sturdy. It’s a little bit heavy, but not so much that it’s annoying. Great adjustable option for plyometrics and other strength training.

These are great jump boxes. I got the set of four. These are part of my home gym, and are a needed piece of equipment in my opinion. I use them not only as steps/jumpboxes, but also as a bench/stool during workouts. I mainly do HIIT/Les Mills on Demand workouts and these are great. I also like that after workouts, I can use these as side tables. The boxes are stable for doing plyo jumps (I use them on cement, they have rubber feet on the bottom) and they stand up to 300 pounds of weight. I highly recommend these.

Excelente producto.....muy buena calidad de materiales....tiempo de entrega tal cual prometió muy recomendado.......todo un éxito.....lo súper recomiendo a todos los que les gusta el ejercicio

Returning as it arrived damaged. I don’t think it’s safe for exercise use anymore. Not sure how that corner is so bent because the box looks very sturdy, the packaging that it arrived in wasn’t damaged. Maybe it was like that from factory. Also £120 for delivery is a scam! I didn’t realise until I received it.

Missing rubber foot for one of the legs. Not in the box. So now it wobbles on the floor as soon as you stand on it.

High quality sturdy product with fast delivery. I have used the product numerous times and like the solid metal frame and rubberized top. It does not move when I use it for belt squats and I have loaded if up with heavy weight and it just feels solid.

Muy buena calidad y buen tamaño para lo que yo buscaba. Esta excelente para hacer ejercicios de pierna porque esta un poco mas elevado que un step normal pero no tan elevado que haga muy difíciles los ejercicios. Ocupa poco espacio en casa y es una buena pieza de mi equipo de gym en casa.
