Middle Abs

 

Lie on the floor with knees bent to 90 degrees and hands lying on the middle part of your stomach.
Start the exercise by contracting the middle abs under your hands; you should feel the contraction.
Once the abs are contracting, slowly curl your head upwards only about 6 inches.
Hold the contraction for two seconds, then relax back to the floor.
Repeat the movement until you feel moderate fatigue in the muscles.
