Core activation
Muscles used in this exercise
Core muscle (transversus abdominus), and the abdominal muscles.
Purpose
Prevention of lower back pain. The core muscle acts like a corset to protect your spine and fasten your abdomen. The core activation should hopefully become automatic with your daily movements.
To do this exercise
Lie on your back with your knees bent and feet approximately in line with your hips
Place your fingers approximately 2 cm in and 1 cm down from your pelvis bone
Gently pull your lower stomach (below your belly button) up and back toward your spine and you should feel the muscles tighten under your fingers
Try to maintain the tension as you breathe in and out for 10 to 20 seconds
Keep your upper stomach muscles (above your belly button) relaxed
Continue to breathe normally as you perform this exercise
