Back pain can present in a few different ways, which we had discussed in a previous post . Today we are dealing with the iliopsoas and how dysfunction in this muscle can present as back pain The iliopsoas is involved in hip flexion, but due to its insertion at the 12th vertebrae of the thoracic spine and first through fifth lumbar vertebrae, it is better classified as a postural stabilizer. The psoas hooks up to the lowest part of the back and then extends down to the lesser trochanter on the medial side of the femur. This means that an irritated psoas can be felt from your lower back and buttock all the way down to the middle of your inner thigh. That's a big pain and you know where you will feel it! Psoas tendonitis can be caused by shortening the muscle due to anterior pelvic tilt (does your booty look like J.Lo?), overuse (too may hills during a run or just too much running/walking), or poor posture (are you really supposed to bend over that way?).

His short term gains may have been significant, but perhaps he should have been compared to someone who was malnourished, etc. in order to better prove causation. There is an important causation, but it depends on the type of calories you consume. Calories come from carbohydrates, protein, and fat. Carbs burn first, then fat, and finally protein. If the body needs energy quickly and you do not have enough carbs for energy, and the fat is taking too long to break down, then your body can turn to protein, and this can lead to inhibition of lean body mass gain...
