If you are looking for an effective and cost-friendly way to improve your vertical leaping ability, you might want to give the HOPZ Vertical Jump Trainer system developed by SKLZ a try.
The HOPZ resistance training system has been designed to promote and develop explosive leg drive and power, strengthen key muscles in your lower body and maximize your vertical. Recommended for users ranging in size from 5 foot 4 inches to 6 foot 2 inches, the system comes with an adjustable belt that fits most waist sizes, ankles straps with built in shoe harnesses, and durable training bands that offer resistance ranging from 20 to 40 pounds. All of it easily fits into a small nylon bag, making it easy to transport for workouts on the go. While there is an initial adjustment period in getting used to the feeling of being strapped in, you can quickly jump into using the product once it is attached.
I have been training my 12-year old son with this product for the month, at the 20 pound resistance level. The best part about the HOPZ Vertical Jump Trainer is that is can easily be incorporated into sport-specific workouts. We use it for basketball training and he wears it two to three times a week during our normal basketball one-on-one skills training sessions, we have seen an increase of two inches on his vertical leap, in this short period. Offering resistance on vertical leaps, side to side movement, and sprints, it appears to be the most effective portable training tool for sport-specific workouts.
One suggestion I would make is when attaching the ankle straps under the heel of your foot, is to take your shoes off first, slide on the heel strap, then putting the shoe over it to hold it in place. If you set up the straps outside the shoe, as the training manual demonstrates, the heel straps have a tendency to slide off in the midst of workouts. Keeping them inside the shoe, helps secure them in place and will help you avoid wasting time in re-setting them up.
