1. What is a commercial leg curl machine?

A commercial leg curl machine is an exercise machine that targets different muscles of the legs. The main target muscles are the hamstrings and quadriceps. They are the muscles of the upper thigh region. 

This machine helps to strengthen the muscles and ligaments of these regions. It is required to build a balance between the front and back of the leg thus prevent injuries.

Seated Leg Curl Machine

While using a seated leg curl machine, the user can remain in a sitting position while performing the exercise. This type of machine allows different knee-bending positions at a 45-degree, 90-degree, or fully bent position. 

The difficulty level varies with each knee bent position.

  1. 45-degree is  the easiest
  2.  90-degree is  harder 
  3. full bent position is the hardest position with maximum gain

This type is more secure and stable, especially for beginner users.

In this position, the leg is in a lengthened position. Thus, it targets all 3 muscle fibers of the hamstring, leading to greater gain.

Lying or Hammer Strength Prone Leg Curl Machine

In this type, the user is in a lying upside-down position, placing the backs of their ankles underneath the pads.

This machine places the hamstring at a shortened position and the hip is almost at a neutral position. It leads to lesser gain as compared to the seated leg curl. However, the lying leg curl position helps to minimize lower-back stress.

Standing Leg Curl Machine

While using this type of leg curl machine, the user must stand with the roller pads at the back of their ankle. It also includes pads on the front for users to place the arms. The Standing Leg Curl machine is used to target the muscles of buttocks, calves, and hamstring. 

Seated / Lying (Dual) Leg Curl Machine

This type of leg curl machine provides dual functionality. Its seats can be adjusted to allow users to enjoy both seated and lying positions.
