Keiser A250 - Lower Back

A250 LOWER BACK

MODEL 2821

PRO­TECT­ING YOUR BACK FOR LIFE

Keis­er’s A250 Low­er Back dif­fers from any of its com­peti­tors on the mar­ket. It focus­es not only on build­ing mus­cles, but also pro­tect­ing them. Unlike con­ven­tion­al machines that use iron, the A250 Low­er Back’s low‑inertia design gives you a smooth resis­tance. This can help pro­tect joints and con­nec­tive tis­sue from shock load­ing. The result is a safer work­out. And it’s per­fect for peo­ple at any fit­ness lev­el — from old­er adults to elite athletes.

WHY CHOOSE THE A250 LOW­ER BACK?

Low­er risk of injury. Pain-free range of motion.
Achieve your train­ing goals faster
Train at any speed — unlike con­ven­tion­al equipment
Unmatched ver­sa­til­i­ty to achieve any goal
