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.
- 45-degree is the easiest
- 90-degree is harder
- 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.
