The glutes are the largest and strongest muscle group in the human body, and they're the primary driver behind hip extension in every squat, deadlift, lunge, and hip thrust. Despite their size, they're commonly undertrained because squats and deadlifts alone don't fully develop them, leaving a gap that direct glute work is needed to close. Hip thrusts and glute bridges are the most effective isolation movements because they load the muscle at its strongest range of motion, near full hip extension, in a way squats can't replicate. Cable kickbacks and abduction work target the smaller glute muscles that stabilize the hip and pelvis, which heavy compound lifts mostly skip over. Train glutes in the 8 to 15 rep range, two to three times a week, since the muscle handles volume well and recovers relatively fast compared to quads or hamstrings. The most common mistake is assuming squats alone are enough, when in reality squats bias the quads more than most people expect unless stance and depth are deliberately adjusted. A second is using too light a load on hip thrusts, a movement where the glutes can typically handle far more weight than lifters expect. A third is skipping the squeeze at the top of the rep, rushing through the strongest part of the range instead of pausing to actually contract the muscle. Barbells are the standard for hip thrusts and heavy compound work, while cables and bands suit the smaller isolation and stability movements around the hip.
