Best abdominal muscles

   The abdominal muscles—rectus abdominus and the internal and external obliques—are part of the group that form the trunk musculature. Weak abdominal muscles are a cause of bad posture and may be a predisposing factor in chronic lower back pain. Strengthening these muscles will firm the waistline, improve posture, and result in a trimmer appearance. However, abdominal exercises do not spot-reduce fat from around the abdomen and waist . Fat is lost only by expending more calories

than are consumed.

   Abdominal exercises may be used for fully defined muscular development or as a warm-up routine for other exercises and sports . In a muscular development routine, abdominal muscles are strengthened by:

 

1. increasing the number of repetitions per set

2. increasing the number of sets

3. progressively shortening the rest periods between sets

4. increasing the angle of the exercise

5. strapping on leg weights for some exercises or holding a weight plate while performing other exercises.
