Sky king calf isolator

Does this machine work for increasing vertical leap?

Short answer is: not really

Also, way too expensive. It will gives your calves a lil workout, but that’s not going to improve your vert. Same thing with “jump insoles”

Don’t waste your hard earned money. There are many other free workouts you can do if you put the work in. No shortcuts. No excuses. Go checkout kneesovertoesguy on instagram or YouTube.
