The most effective way to grow and tone your booty is through weightlifting. The glutes are the largest muscle in your body and require very heavy resistance to see results. Weighted hip thrusts isolate the glutes without compressing your spine, making them a top booty workout that almost everyone can perform. The thruster is designed with several goals in mind: Effectiveness: To effectively work out your glutes, very high resistance is required. The Thruster comes with 135 lbs of resistance, and we sell extra 70 lb bands. BootySprout is safe up to 450 lbs of resistance! Ease of Use: Barbell weighted hip thrusts require significant setup time, both before and between sets. Simply open, strap in, and thrust! Collapsible: The thruster can fit into even the tiniest of apartments! It weighs 22 pounds and easily folds up to 2 feet 1 inch x 2.5 feet x 7 inches. It can be stored flat under most beds or stood up in the closet. Safety: Significant weight is required to effectively grow and tone the glutes. Moving around 90+ lbs at a gym is difficult to manage, and placing heavy dumbbells on your lap is dangerous. Resistance bands are a much safer method to hip thrust with high weight. Our high resistance bands easily clip in to BootySprout, and they are covered in nylon for extra safety! Affordability: We wanted to make the Thruster available to everyone, and our goal was to achieve a price under $200. Durability: Thruster is designed to last 20+ years. It is constructed out of powder-coated steel, an industrial strength hinge, custom high density NBR foam, custom high quality resistance bands that have successfully fatigue tested 500,000 cycles, and a 0.75 inch thick wooden board. Fun: An added benefit is that they are FUN. The motion is easy to perform, and you will continually find yourself wanting to get in a couple more sets…just like we did!
