I think I first heard this from the ingenious Charlie Weingroff. It makes perfect sense. There are your limbs and what your limbs connect to. That interweaving of connections is your core.

If you are quad dominant, you have thick thighs and no butt. If you are a quad dominant athlete, you train often, making strong parts stronger. Certain parts of your legs get bigger, but your butt stays relatively flat. Tight hip flexors get tighter. The pelvis anteriorly tilts, rotating the top forward.

The erector spinae on the left are your low back muscles. When the pelvis is shifted anteriorly, those erectors have a hard time shutting off. If they can’t shut off, your lower stomach muscles can’t turn on. Tension in the body follows the rule of reciprocal inhibition: when a muscle contracts, it’s opposite must relax. Not only does anterior tilt cause back pain, it thickens and strengthens the hip flexors, further minimizing abdominal activation.

- Dysfunctional butt = dysfunctional core
- The hip flexors control the gyroscope of a pelvis
- Anterior pelvic tilt leads to ab and butt death
