Sitting shuts off glutes and core. Your back overworks. Move again
Sitting all day makes your hips tighten up in all 360 degrees around both hip joints.
Your glutes - designed to do the heavy lifting - stop doing their job.
Some people call this gluteal amnesia.
Instead, your lower back takes over. Your glutes underwork. Your lower back overworks.
Worse, sitting makes your deep abdominal musculature practically go to sleep. It disconnects from your brain.
Those muscles designed to stabilize your spine and hip so your body can move freely? They no longer do their jobs.
And your lower back gets stiff, tight, sore, and painful.
Stay Strong,
Geoff Neupert.
