Jean Blanchard I like the feel of it and works like a charm for the body.

Anonymous Great quality compact strength trainer.
Not really useful for legs, and range is restrictive for people with long limbs.

Vergil Hudson The Steel-Bow is much better for over coming my full body electrical damage. I've been using the regular Bull worker since the early 1972 but proved to be too long to use on my upper body. However this one has eliminated that problem. Seek and you shell find what is need for success.

Ethan Halpern Excellent tool!
Thank you!

Gerald firestone Finding it easy to use and is giving me a good workout.
-
“I don’t have time for long workouts.”
Targeted tension makes short sessions highly effective.
-
“I want muscle definition without wrecking my joints.”
Constant resistance builds muscle with control and low impact.
-
“I don’t want bulky equipment.”
The Steel Bow fits in a backpack — and trains your entire body.
