Question: Does the facilitated workout strengthen bones, too, i.e. impact their density simiiar to weight-bearing exercise? Thanks!

Overall this is an excellent item for those who need to strengthen and improve their core and lower body muscles(for both jumping and running).
If I had used it longer, I'm sure I would have had bruises on my upper hip. Terrible.The poor fit aside (petite ladies--beware! ), the contraption itself didn't strike me as versatile. It specifically advizes to not to use the product for any other exercise than the small handful in the manual.
I don't think of my ankles as particularly thin, but they are smaller than the velcro strap. (The ankle attachments are pulled up as you stretch, so they do tighten around the calves. )OVERALLAs it is, this set is fine for isolating quads and glutes. Assuming it fits you like it did me, you'd need to be motivated to exercise these muscles to work through the discomfort.
However, once you get the hang of it, the resistance really can add to your exercise routine. By doing standard jumps, side-to-side hops, and even runs you add real resistance to exercise movements. This definitely can increase strength and stamina. If you do repeated, rapid movements you will also increase your agility.The feeling is a bit stiff and awkward at first, but after a while it is more natural.
When I stood up straight, I definitely felt a lot of pull, but I was able to exercise with good form. I went through the basic set of exercises described in the booklet (vertical jumps, broad jumps, lateral jumps, lunges), and I worked up a good sweat and definitely felt like my legs and glutes were working hard.
I can't say that I have a vast experience with vertical trainers, but SKLZ is a great company that turns out well made exercise equipment at a reasonable price. So when Vine offered this item, I--to use a phrase--jumped for it.The vertical jumper comes with a belt, two foot attachments, and two sets of cables (one light--7.5 inches--and the other heavy--5.5 inches). It also comes with a small instruction manual.
I was hoping for something that would be useful for more than one thing: jumping. Not only was that not the case, but it didn't even fit me. I am roughly 5'4, fairly muscular, and 123 lbs, and it did not fit me snugly on the waist. Because of this, when I attached the bands from my ankles (also very loose) to my waist, the waist band would slide down and push on my hip bones.
I am always looking for new, effective ways to train, and this got my attention. It will increase your vertical jump height and also strengthen your legs.I was not able to do an exact measurement of my vertical jump height, but I notice a positive difference when I use my pull up bar. I mounted my pull up bar outside, and pretty high. The bottom of the bar is 12 inches higher than what I can reach fully stretching and on my toes.
SKLZ HopzI've used other SKLZ equipment with good success, but this one is iffy to me. I'm 6'3" and didn't realize there was a recommended height limit of 6'2". This made it extremely uncomfortable for me to fully extend the tension straps. The Cordura ends of the straps kept chaffing my legs and the belt would dig into my hip bones. I was also concerned about the straps possibly snapping.
