Sit upright on a flat bench with feet flat on the floor, holding a dumbbell in each hand at thigh level with arms at sides and back straight against the bench
2
Grip dumbbells firmly with neutral grip (palms facing each other), engage core, and position feet hip-width apart on the floor for stability

Lower your body by bending at the hips and knees simultaneously, descending into a squat position while keeping dumbbells at sides, chest upright, and knees tracking over toes until thighs reach parallel to the floor

Drive through heels and extend hips and knees to return to starting seated position on bench, squeezing quadriceps at top of movement and maintaining upright posture throughout
