PER4M Jump Trainer for Athletic and Resistance Training, black

I wanted to buy a jump trainer for my 9-year old son but I didn’t think any of them would fit. He’s 5 foot & really skinny, maybe 85lbs And I can’t believe this actually fits. I have him use the longer bands so that it’s not too much resistance for his little legs, and it works great. I’m not sure how it would work on a bigger/taller guy, but I can confidently say it should work for smaller adults, high school/middle school kids, and even tall 4th/5th graders.

Great product, bought it about 2 months ago and it's still in great shape. I use it when doing squats , makes a noticeable difference in explosiveness but you must be consistent, I use it about 2-3 times a week, still in great condition. Only con would be that the resistance bands rub on your calf but an easy fix is just to wear compression tights or long socks.

Bought it for My Son to help him with his Training with Basketball. He been doing pretty good with it and he Loves it. Very Sturdy and very good Resistance!

Good idea with a design flaw. The loop for the feet is not adequate. The images show the loop to be worn outside the shoes. If it is indeed used that way, these loops will and does wear out very fast and will fail after several hard exercise sessions. In addition, they often come loose. Secondly, if you wear the loops inside the shoes, during the exercise session, they also have a tendency to come out. Then, the whole stress is applied to the ankle straps causing excessive abrasion to the ankles. I think the loop has to be redesigned. Otherwise, it is a good product and useful.

Waste of money. This product is worn around your waist like a belt, and rubber bands hook up in the back of the belt which are connected with a clip to a device you attach to the back of your shoe or foot. The device for connecting to the shoe or foot comes off easily, and the rubber bands pulling at the back of the belt pull the belt down below your butt no matter how tight you cinch the velcro belt. Not well engineered. Disappointed, and threw it away.

I was looking for something to add with lower body workout for my ass n thighs and I can already tell after my first day this is gunna be my secret weapon. So ladies if you are killen yourself with squats but don't feel or see a difference then I suggest u add this in . For only $20 you really can't complain.

This is a great workout and training tool. My fiancé uses it to train our two little ones for basketball and I use it to get a great workout in. The straps will fit almost anyone. They may make you walk funny when your getting in position for workout but you will feel the burn soon enough.

My so has been using these for about a year now. Definitely increasing leg power and vertical. Follow all the drills on you tube to perform. Only question I have is it came with two different size bands. I guess you could use either depending on your height but the short one is really short.
