Comerford and Mottram, 2001; L. Herrington and R. Davies 2003
The transversus abdominis is the deepest muscle of the abdominal muscles involved in the stability of the trunk during movement. Pilates involves more contraction of the transversus abdominis than conventional abdominal exercises. Thus, during everyday movements, its action allows you to act safely. This has been proven on women with an average age of 32 years who practiced 1 to 2 sessions per week for 6 months for 45 minutes.
