FEEL: You should feel the abdominal muscles engaging while you perform this exercise.
COMPENSATION: Do not arch the back as you perform this exercise.
FEEL: When you drop your hips you will feel the abs and the low back stretching into the arched position. When you bring your body down towards the floor you will feel the low back muscles being stretched.
“Approximately 34% of people who experience acute low back pain (LBP) will have recurrent episodes. It remains unclear why some people experience recurrences and others do not, but one possible causes is a loss of normal control of the back muscles (1).”
When it comes to the literature investigating acute and chronic low back pain, there is a handful of evidence supporting altered muscle function and recruitment. The muscles that are typically affected are the deep back and core muscles including the lumbar multifidus and the transverse abdominus. The function of these muscles and other core muscles including the obliques, erector spinae, and rectus abdominus is to provide stability by creating a stiffening effect on the spine (2).
Doing everyday tasks such as squatting, picking objects up off the ground, and lifting things overhead can be very difficult for individuals with LBP. Ultimately the body needs to keep MOVING and people should not be AFRAID to move their back!
Check out this drill designed to promote controlled movement at the low back and pelvis and decrease muscle guarding. A swiss ball is a great object to start as it is light, and it decreases the depth of a squat limiting any excessive posterior pelvic tilt and lumbar flexion, which may be sensitive to some.

FEEL: You should feel your core and back muscles working as well as your arm muscles to maintain optimal position and form. You may also feel your hip and thigh muscles working as well to maintain position.
COMPENSATION: You should step away from the anchor until there is enough resistance that is challenging, but not too hard where you can’t maintain optimal form. Do not let the band rotate your upper body, keep your arms straight and hips facing forward. Try to avoid twisting your back.
FEEL: You should feel the side towards the floor working, from your outer hips to outer core and shoulder that is against the floor.
COMPENSATION: Avoid sagging your pelvis, hips, or shoulder as you side bridge up into this position.
FEEL: You will feel the muscles on the back of the arm and the leg that are lifting up towards the ceiling. You will also feel the lower back work with this exercise.
COMPENSATION: Avoid arching the lower back as you elevate the arms and the legs.
