LEG EXTENSION (ONE LEG):

Muscles worked:
Quadriceps
Instructions:
  • Sit in a leg extension machine with your legs behind the roller pads and your hands grasping the machines handles or the sides of the bench.
  • Your knees should be bent at a 90 degree angle and have the seat or bench against the back of your knees with your toes pointing in front of you.
  • Slowly extend (lift) one leg at a time contracting your quadriceps until they are almost straight out in front of you, without locking your knees at full extension. Hold that position for a split second while flexing your quadriceps.
  • Return to starting position slowly, in a controlled manner.
Don'ts:
  • Don't lock your knees at full extension.
  • Don't jerk the weight up.
  • Don't let the roller pad just drop down, be sure to let the weight down slowly.
Alternate exercises:
Note:
  • Do a full set with one leg and then switch legs--don't alternate each repetition.
  • There is very little, if any, difference in how the quadriceps is worked compared to the leg extension. Doing one leg at a time is simply to add variety to your program.
