Re: Luke Lowrey--Double Your Vertical
i heard it works pretty good but it won't nowhere near double your vertical, unless you start out with like a 12 inch vertical or something. like 8 to 10 inches is more like it.
so if you start out with like a 28, you'll end up around 36 or 37, which is higher than the average for nba players.
it's facking expensive tho.
