Leg Extension

Muscles Worked

Muscles worked by leg extensions



  • Adjust the machine so that you are correctly positioned. Your knees should be in line with the machines joint.
  • Extend your knees with control, until they are completely straight.
  • Slowly lower the weight again.


Leg extension is an isolation exercise where it is easy to focus on the quadriceps.

Be careful when adjusting the machine, so that it suits your body. Besides getting your knees in line with the machines joint, try to get the longest comfortable range of motion.
