HIP THRUSTER WORKOUT: The glutes are one of the largest muscle groups in your body and require heavy resistance to see results. Our glutes trainer provides the easiest and safest way to perform high-resistance hip thrusts or glute bridge exercises. For additional resistance, purchase our 45- and 75-lbs bands. GLUTE ISOLATION: This exerciser works out your glute muscles to tone and strengthen your booty. It isolates the three main gluteal muscles, making it a great complement to weightlifting, running, swimming, and other fitness routines.
