The goblet squat holds a single dumbbell vertically against the chest while squatting, using the front-loaded weight as a natural counterbalance that keeps the torso upright. It trains the quads and glutes while grooving squat mechanics, which makes it the standard entry point for learning to squat and a solid high-rep quad option for experienced lifters. One dumbbell of 10 to 24 kg covers most people's needs.
