Hunching over your phone or at your desk puts an additional 60lbs of extra pressure on your spine causing wear and tear to your spinal cord, disc degeneration, herniation, surgery, nerve damage, headaches, compromised shoulder function, and compromised athletic function.
Forward head-on neck position from slouching leads to compromised jaw mechanics, and is a source of teeth grinding and jaw dysfunction, jaw pain, and headaches.
Sitting with rounded shoulders with poor neck position can cause compromised neurodynamics and collapsed nerve tunnels, which can cause carpal tunnel syndrome.
Too much sitting can lead to shortening and tensioning of the quadriceps and calves which can lead to mechanical knee pain.
Decreased muscular activity caused by sitting leads to decreased lymphatic flow and increased lower extremity congestion and swelling(aka”kankles”).

Slumping over in a chair creates internally rotated shoulders which can cause shoulder impingement, rotator cuff dysfunction, instability, “douchebag” shoulder, and general shoulder pain.
A rounded or over extended sitting position can lead to compromised diaphragm function which results in poor breathing patterns, decreased VO2max, decreased spinal stabilization, and increased stress breathing patterns which can lead to poor sleep, poor fat metabolism, early death, exacerbation of breathing disorders (asthma), compromised ability to down-regulate at night
Too much sitting is the root cause of non-specific low back pain, stenosis, and disk pathology.
Sitting is a contributing factor to hernias because sitting trains the abdominal wall to function poorly, making sitters more susceptible to hernias.
Prolonged sitting compromises pelvic floor function which can lead to bladder incontinence, hemorrhoids, poor spinal stability, and sexual dysfunction. Peeing yourself is NOT normal.
It is not natural for your hip to beat a 90 degree angle all day. Sitting causes compromised hip function, impingement which leads to osteoarthritis, shortening of tissues, and compromised athletic ability.
