You will continue to see these modifications referenced throughout courses as they are important reminders when practicing:
PREGNANT
Avoid any movements performed face-down and modify to a side-lying position throughout. Beyond 20 weeks, side-lying is recommended over lying on your back. Seated and side-lying variations are appropriate throughout all trimesters.
PAIN
Add cushioning beneath your body with a folded blanket before beginning. All of these movements can also be done in bed if a firmer floor surface feels uncomfortable.
HIPS
For seated exercises, elevate your hips above knee height by sitting on a folded blanket or firm cushion. When lying down, support beneath the knees as needed for comfort.
BACK
Gently draw your navel toward your spine throughout each movement to support your lower back. A folded blanket beneath you can help, and side-lying is always a good alternative if back-lying causes discomfort.
NECK
Support your head with a pillow during all floor-based movements. Allow your jaw to stay soft and unclenched as you move through each exercise.
