Exhale, and lift back up to the starting position. Strive for controlled, even movements. The front foot remains pointed straight ahead throughout the exercise. Lunges are one of the best examples of an exercise that improves functional fitness because they help ready the body for any number of everyday moves. They also enhance agility and balance.
Lunges call for the exerciser to have a great deal of body awareness.
If you find your unable to do them, stick with dips until you develop more awareness of your body. Also if you have knee problems do the exercise as described but don t lower your body quite as far. Step back from the rack and stand with your feet hip-width apart. Both feet are pointing straight ahead. Exhale, coming back to the starting position.
