Keiser A300 - Seated Calf

A300 SEATED CALF

MODEL 2936

EXPLO­SIVE, BAL­ANCED POWER

The A300 Seat­ed Calf was orig­i­nal­ly designed for world record hold­ers Willie Banks (triple jump) and Mike Pow­ell (long jump). It fea­tures uni­lat­er­al move­ment to help devel­op bal­anced explo­sive lower&8209;leg pow­er. The machine auto­mat­i­cal­ly pre‑loads and adjusts for leg length. Unlike con­ven­tion­al machines that use iron, the A300 Seat­ed Calf’s low‑inertia design gives you a smooth resis­tance. The result is a work­out unlike any­thing else on the market. 

FEA­TURES YOU WON’T FIND IN CON­VEN­TION­AL MACHINES

  • Bilat­er­al move­ment to train mus­cle symmetry

  • Increased resis­tance range for more intense func­tion­al workouts

  • Large dig­i­tal dis­play that shows resis­tance, sets, rep­e­ti­tions, and peak power

  • Thumb but­tons let you change resis­tance with­out chang­ing posi­tion — even dur­ing exercise

  • Fast, easy, and pre­cise eccen­tric overloading

  • Change resis­tance in incre­ments as small as one pound

  • Indus­try-lead­ing lifes­pan and uptime for years of use

  • Unique ver­sa­til­i­ty; five ways to train instead of only one

  • Ful­ly adjustable to accom­mo­date a wide range of users
