• Arm and shoulder strength is multiplied as you use your own body weight for resistance.
• Lats and other back muscles begin to support the spine better than before.
• Abdominals and obliques are refined and sharpened through building core muscles.
• Poor and average posture begins to correct itself over time.
• Hip flexors are stretched and rebuilt.
• Glutes, quads, hamstrings, and calves are tightened and lengthened where they need to be.
