The hack squat is a popular leg-focused resistance exercise performed using a hack squat machine. It closely mimics a squat movement while providing back support, allowing lifters to focus on quadriceps development with reduced strain on the lower back.
This exercise is commonly used in strength training, bodybuilding, and hypertrophy programs to build strong, well-defined legs.
