The iliopsoas is actually two muscles: the psoas and the iliacus. The psoas originates from the vertebrae T-12 vertebrae (the vertebrae where the lowest rib attaches) down to L-4. The iliacus muscle comes from the inside of the hip bone. Once the two merge, they attach to the top of the femur (thigh bone), on the inner surface.

Pregnancy “Planned”

I had 3 goals in 2019: PR a half marathon in May, run the Chicago marathon in October and get pregnant in November. I had a “plan”, so what could possibly go wrong?
