The Glutebuilder Box is a specifically designed training box designed to maximize muscle activation of the glutes, hamstrings, and quadriceps through exercises such as hip thrusts, step-ups, Bulgarian squats, and deadlifts. Its reinforced structure and precise height allow each repetition to be performed at the optimal angle, avoiding joint overload and promoting proper postural alignment. This multifunctional tool is covered with a non-slip surface for added safety and can be combined with bands, bars, or dumbbells. It is ideal for both aesthetic and strength routines and is indispensable in training boxes, boutique gyms, or women's training spaces.
