Benefits of Pilates
Pilates is a body conditioning routine that helps build flexibility and long, lean muscles, strength and endurance in the legs, abdominals, arms, hips, and back. It puts emphasis on spinal and pelvic alignment, breathing to relieve stress and allow adequate oxygen flow to muscles, developing a strong core or center (tones abdominals while strengthening the back), and improving coordination and balance. Pilates' flexible system allows for different exercises to be modified in range of difficulty from beginning to advanced. Intensity can be increased over time as the body conditions and adapts to the exercises. No muscle group is under or over trained. It enhances core strength and brings increased reach, flexibility, sure-footedness and agility.
