Just curious if anyone here has a Tri-Max or is old enough to remember
them? The Isokentic concept is nothing new but the Tri-max made it's
debut in the early 80's. Supposedly a big majority of the Texas Fire
Departments adopted this machine as well. I've had mine almost 25
years and it's still serving me.

For me Isokentic work outs break up the monotony of weights. It attacks
the full range of motion. It's really a muscle pumper because it's
bi-directional and attacks both push and pull muscle groups at the
same time. I know it's made me almost pass out several times.
Just curious if anyone experienced this type of workout and
what they think.

Heres a Popular Mechanics add from years ago.
