Dead Strength is defined as the ability to produce high levels of muscular force with minimal contribution from elastic tissues (fascia, skin, ligaments, tendons).
Deadstarts are a type of Dead Strength that demand the necessary force output to overcome resting inertia.
Deadlifts are defined as overcoming a mass' resting inertia and moving the mass vertically (against gravity).
Deadshifts are defined as overcoming a mass' resting inertia and moving the mass primarily through gravity (perpendicular to gravity).
Ground-to-Standing techniques involve overcoming one's own resting inertia from various on-ground to standing postures.
