Description

Drop squat machine {Drop squat machine}

The present invention relates to a drop squat machine, and more specifically, to a drop squat machine that is convenient to apply to various user body sizes and is provided with a back cushion to guide a posture with high exercise efficiency.

Squat means a bending exercise, and generally refers to an exercise in which one carries a barbell on one's shoulders, squats deeply, and then stands up. It is an anaerobic exercise and is considered one of the three major weight training exercises, along with deadlifts and bench presses.

The general squat exercise strengthens the muscles of the lower body by repeatedly sitting down and standing up while lifting a barbell or dumbbell. However, squat exercises using barbells or dumbbells can cause injury if the user loses their center of gravity.

Taking this into consideration, squat machines that can prevent user injuries have been developed recently, but problems such as not being able to guide postures with high exercise efficiency and not being applicable to various user body sizes have occurred. did.

Therefore, research is required on a drop squat machine that is convenient to apply to various user body sizes and has a back cushion to guide a posture with high exercise efficiency.
