Lying Leg Raise exercise targets the
lower abs, but also involves the hip
flexors to a large extent. If you have
any lower back problems it may be wise
to avoid this exercise as it can place
torque on the lower back, especially
if done incorrectly. The thrust part
of this movement involves the lower
abs in a different function...basically
supporting and stabilizing the legs
as you push the legs upwards.

the beginning and end of each set. It
is important to maintain constant tension
in the ab muscles and letting the feet
touch the ground releases the tension
in the abs.
