I’ve been looking for such a product from stores like sports authority for quite a while but failed to find one, and started to think building one myself until I found Vita Vibe. The maximum bar height of the original FB4 is a little bit lower than my desired height, but they increased it by 10 inches to meet my target. Now it works great! Strongly recommend this product.
