Is there no coach in the gym? The trump card action of thigh shaping: dumbbell (or freehand) lunge, which has the function of lifting hips and abdomen. Step forward, the front side of the thigh is parallel to the ground, at 90 degrees to the calf, the knee joint sinks backwards, without touching the ground, and the big and small bends are at 90 degrees, alternately moving forward, hands naturally hang down, holding dumbbells, not too heavy, or hands are supported on both sides of the waist without load, and turn back 20 meters. Or cut, squat down in the same place. Combined with aerobic exercise, you try it.
