When you start leg exercises and you want to focus on the quadriceps, the best choice for this would be leg extensions. Leg extensions are a must-have for every leg workout if you want your legs to look great and be well-defined.

One of the ways to do this exercise is to use the leg extension machine. The leg extension machine, as you can see in the picture, is a machine in which the movement is executed by sitting on its chair. The muscles that are involved in leg extensions are the quadriceps. Next, I will explain step by step how to do this basic leg workout exercise.

How to do a proper Leg Extension:

  1. Sit on the machine’s chair and grab the handles really tight in order to keep your body from moving.
  2. Bend your legs and place them under the special brackets of the machine.
  3. Start lifting your legs until they reach a horizontal position.
  4. Don’t forget to breathe out at the end of each rep.
