Description
Leg Extension Machine
A leg extension machine is a strength training machine designed to isolate and strengthen the quadriceps — the muscles located on the front of the thighs. The user sits on the machine with their legs positioned under a padded lever and extends the knees against resistance.
This controlled movement places maximum emphasis on the quadriceps while minimizing involvement from surrounding muscle groups, making it ideal for targeted leg development, rehabilitation, and strength training.
