Fitness tip: Seated leg extensions

Thursday, December 13, 2012

Target body part: Legs

Primary muscles: Quadricep

Secondary muscles: Gluteus maximus (buttocks), hamstring (tendon behind the knee)

Equipment needed: Leg-extension machine, chair with ankle weights

Starting position: Choose your weight and sit on the machine, adjust the pad so that it falls on top of your leg (just above your feet). Make sure your legs form a 90-degree angle between the lower and upper leg. This keeps the knee over the toes, which in turn prevents undue stress at the knee joint.

Upward phase: Using your quadriceps, extend your legs to the maximum as you exhale. Keep the rest of your body stationary on the seat. Pause a second on the contracted position.

Downward phase: Slowly lower the weight back to the original position as you inhale, do not go past the 90-degree angle limit.

Repeat: 3 sets, 12-15 repetitions

Next week: Holiday Express Workout (multiple muscle groups)
