Before squat racks, before protein shakes — two men in 1905 built legendary leg power through deep, raw movement. The history of the hack squat and the two strongest humans of their era.
The hack squat, the Bulgarian split squat, the Jefferson deadlift, the Zercher carry — who named these things and why do they sound like wrestling moves from 1923? A guide to exercise names around the world and throughout history.
The horse stance — an ancient martial arts hold that builds leg strength, mental toughness, and breath control. Here's the history, the biomechanics, and a 30-day challenge to make it yours.
The deep squat hold is the T1 foundation of the entire squat progression — and a diagnostic for how much mobility work you need before loading.
The box squat gives you a controlled target depth and removes the stretch reflex — building real strength at the bottom of the movement.
The air squat is T2 — the foundational bilateral squat pattern at bodyweight. Here's what owning it actually looks like and why most people don't.
The pause squat removes the stretch reflex from the full air squat — building raw bottom-position strength that transfers to every unilateral variation above T2.
The Bulgarian split squat is T3 — rear foot elevated, front leg doing the work. The single-leg strength and hip flexor demand here are the direct path to the pistol squat.
The Cossack squat trains lateral hip strength and adductor flexibility simultaneously — a movement almost no one does and everyone needs.
The shrimp squat is a single-leg squat with the rear foot held behind — building deep unilateral strength and balance that directly precedes the pistol squat.
