A simple Back extension whether called Pilates or Yoga or a Chek Exercise is all for the same reason – to reverse what we do every day seated and slouching forward – its there to enhance our lordosis and back muscles as wells as posterior arm muscles and glutes. Ensure your legs are in line with your spine – place your hands under shoulders flat and head in line with spine with a slight pull up from lower abs (three notches on an imaginery belt) take a breath in then exhale and lift up into extension with both lumbar and TVA (lower abs) on schronising together as they should to use your postural muscles and repeat 10-15 times with purpose breath and fluidity. ENJOY – before bed and on waking.
