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

We are very pleased with our new adjustable plyometric platform. We have it set to 16 inches, which is a good challenge and leavies 20 inches as a future goal. We love how the platform is very sturdy and stable without being heavy and awkward to move. The aparatus for adjusting is very simple and secure. We had been debating between this platform and one of the "stuffed" cubes. This platform is a better option for portability and stability; highly recommend.

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.

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.

Why did you pick this product vs others?:This item has withstood months of me standing on it and jumping to exercise plyometrically and think the highest two boxes are too high for anyone to use but those make great plant holders and side tables. I really like the design.

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.

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.

Prices vary throughout the year but if you keep an eye out for sales this can be a very good deal. Very firm and stable, useful for a lot of single leg exercises.

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.
