Beginner Abdominals Hip Flexors Strength Fitness Ball Gym

Purpose: This exercise provides flexibility and mobility of the hamstrings.

Benefits: This exercise will assist in giving you strong abdominals.

Position yourself as if doing a pushup with your hands about shoulder-width apart, your feet on a fitness ball and legs held straight out. Your back should be straight and you should look forward not down. This is the starting position. Slowly pull your knees straight in towards your chest, rolling the fitness ball in smoothly. Exhale during this movement. Keep looking forward and your back straight. Slowly extend your legs to the starting position. Inhale during this movement. Keep looking forward and your back straight. Repeat the movement for the required number of repetitions.


The abs can be divided into the abdominals themselves and the obliques. The obliques are the outer abs and are used in twisting movements. For the sake of exercising, the abdominals are sometimes divided into upper abs and lower abs (this is not a technical division but something for exercising). Both upper and lower abs are used in straight line ab exercises while the upper abs are also involved in twisting movements.
