The BUILT Strength Throwback Series Booty Blaster is built around a 45-degree kickback motion with a Kevlar belt-driven selectorized system — delivering quiet, smooth resistance through the full glute extension arc without the cable slack or noise of conventional weight stack machines. The 45-degree angle is biomechanically optimized for maximum glute contraction at the top of each rep, where the muscle is shortest and hardest to load effectively.

Adjustable upper body positioning, elbow pad height, and multiple footplate positions accommodate users of any height — locking in correct alignment before the first rep and maintaining it through the full range of motion. An integrated knee pad and non-slip contact surfaces keep the user stable and comfortable through every set. A 200 lb weight stack on a 615 lb machine base delivers the resistance range and structural stability this movement demands at a commercial level.
