Learn how to perform the lying leg raise from floor position.  The lower abdominals on many athletes are relatively underdeveloped, get them in shape with this exercise.

Primary muscles worked:  Lower Abdominals

Synergist Muscles:  Mid and Upper Abdominals

Mechanics:  Isolation

Equipment:  Open Floor Space

How to perform the exercise:  The athlete can perform the lying leg raise on the floor by laying with the back flat on the floor, with legs fully extended. Next, place the hands together and underneath the body as to support the lower back. After that, lift heels off the ground about six inches. This is the starting position for the lying leg raise. Now, lift the legs up toward the ceiling creating a 90 degree angle with the upper leg and hip. During this motion, the athlete should feel the contraction in the lower abs. Once this position is reached, the athlete may lower the legs back to six inches above the floor.

Spotting the exercise:  If the athlete lacks sufficient core strength, the spotter can assist the athlete by pushing up on the athlete's legs so that they can complete the a repetition of the leg raise.

Sport specific application:  Core strength is very important in all sports. The lying leg raise will assist directly in leg/core power transference as the core works to move the legs throughout the lift. This motion can be seen in a very abbreviated manner in swimming, where the swimmer is kicking the legs to increase forward propulsion.
