ABSTRACT:
Resistance training exercise apparatus includes a poppet load system. During movement of a user-engaged exercise member in a first exercise direction, fluid flows past an open poppet in a first flow direction between housing chambers. During movement of the user-engaged exercise member in a second exercise direction, fluid flow between the chambers is blocked by a closed poppet, and instead fluid flows through an auxiliary passage through a one-way valve. Ballistic training is enabled with the addition of a second auxiliary fluid passage, second one-way valve, and a release valve.
