Since many
oblique exercises involve rotating your torso you can perform side turns
to try something different. Side turns involve stabilizing your body on the
floor and rotating your legs and hips from side to side. In order to get the
side turns to work your obliques you must make sure your lower back is as flat
as possible against the floor. This can be accomplished by not letting your legs
drop so far down to where you cannot maintain this position flat on the floor.
Side turns can be performed at any point of an abdominal workout. Since side
turns tend to overwork the hip flexors, it is best followed by an exercise
and/or stretch for the antagonist muscles such as these dynamic flexibility
leg stretches.
