Beginner Abdominals Hip Flexors Strength Flat Bench Gym

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

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

Lie face up on a supine (flat) bench with your legs extending beyond the end of the bench. Your toes should be pointed. Hold onto the sides of the bench for support. This is the starting position. Slowly pull your knees straight in towards your chest, keeping your toes pointed. Breathe normally. Slowly extend your leg to the starting position. Breathe normally. 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.
