Core stability exercise: the McGill curl up
To avoid creating too much flexion in the lumbar spine, Lee recommends the McGill curl up. To complete this movement, lie on your back with one leg straight and one leg bent. Place your forearms and hands under your low back. Lift your head, chest and shoulders off the floor as much as you can without jutting out your chin.
“Everything moves in one piece like there is a board under you, from the tailbone to head. You might not lift very far, but that is okay,” Lee says. Do two sets of 10, switching legs between sets.
