Getting Fit - Seated Toe-Touch for lower back and abdominal muscles

The seated to-touch exercise is a good exercise for lower back and abdominal muscles. This is one of  the three abdominal and back exercises that are approved by the American College of Sports Medicine. The other two exercises are the standing catch-stretch and the knee to chest.

In this exercise, it is necessary to keep your legs straight and toes pointed. Don't bounce your body. Hold the stretch for four seconds and return to the starting position. Repeat the movement for the desired number of repetitions.

Unlike the traditional sit ups, this exercise is not harmful to your back.
