Actions:Stomach crunch, back extension, hip flexion, hip extension
Benefits: The Hip and Crunch is a specialised stomach and lower back exerciser which firms and tightens the long rectus abdominis muscle with particular emphasis on the upper abdomen.
The knee to chest motion provides improved hip flexion and extension in addition to abdominal strengthening. The crunch movement effectively opens up the spinal vertebrae, relieving spine tension. The back extension extends the spine and strengthens the erector spinae muscles in the lower back.
The combined effects of the Hip and Crunch result in a flatter and firmer stomach, a stronger back and improved hip mobility.
