GoSports 3-in-1 Plyometric Jump Box Set - Adjustable Small, Medium & XL Sizes for CrossFit, HIIT & Home Workouts - Perfect for Strength Training, Agility Drills & Cardio Exercises

This is an excellent box for squat jumps and working out! It is a must have for your home gym, especially if you're into functional fitness, bodyweight exercises, etc. I’ll try to provide you info about the box here:WHICH SIZE IS RIGHT FOR YOU? I got the 30x24x20 box and love it. I previously did squat jumps on our stair case until my wife told me to knock it off (she thought I was damaging the structural integrity or something like that). So I got a tape measure and measured the height of the stairs I usually jump on and decided on the appropriate box to order. The 30” jumps are pretty high but are still doable. I usually stick with the 24” jumps for most of my workouts. If you have another family member who might be shorter, it might be advisable to get the next smaller size box for more a wider range of users. Maybe the box that has the max height of 24" (that’s the size I should have gotten in hindsight). Either option would probably be fine though. I still love my 30x24x20 box. (I’m 5’11” and 185# for reference.)DURABILITYThis box seems super sturdy! I’ve already used it several times and it seems really solid. I don’t have any concerns whatsoever with its quality or construction. I've read some reviews where folks decided to use wood glue to help make it sturdier. This is completely unnecessary. The box is designed really well and even has a support piece inside the box.EASE TO BUILDThis was super easy to put together! I HATE building things, construction, or even routine handyman tasks around the house. This box was so easy, it didn’t bother me at all. It took less than a half an hour to fully assemble and was really simple. The directions were really simplified which helped. To make life easier, please use a power drill. You will save a ton of time and hand/wrist strain. The appropriate drill bit is included with the box as is all of the screws. Just don’t overtighten the screws so you don’t crack any of the wood. I did take out my rubber mallet and only barely used it. If you don’t have one, however, it’s okay as it’s not really needed. The power drill isn’t needed either but you’ll be really glad you used it.SAFETYI already spoke about the durability of construction. This box is also really stable, even using the 30” height (which means the base is narrower). No issues or concerns whatsoever with regards to stability or the box rocking if you don’t land perfectly in the middle. Just a note: Try not to be persuaded to paint the box or otherwise resurface it somehow because that could cause it to be more slippery when you land on it.MISCELLANEOUSEach slab of wood has a rounded edge side and a sharp side. Make sure you have the rounded edges on the outside. This is also explained in the directions too. My components came in perfect condition. No cracks in the wood, and all the hardware was included. I attached five photos to this review to help you evaluate the box and the easy directions. When putting it away after use, stand it up on the highest setting (30” in my case). It will take up less surface area in your room.I hope this review has helped you in some way with evaluating this product. I love it and hope you will too!
