next time you're having a bad day, imagine this: you're a
Siamese twin, your brother, attached at your shoulder is gay
and you're not, but you only have the one ass."
- Jack Handey

extension work to even begin to optimize your athletic potential.
Leg extension dominance over hip extension is the dominant
bio-mechanical fault in athletes and their training.
