This aptly named cable forearms killer is simply a set which alternates
wrist flexion and wrist extension on a low cable pulley. The exercise can be
performed from any position which allows you to support your forearms on your
thighs. This includes sitting on a ball or bench as well as squatting down. The
cable forearms killer is a great way to fatigue the forearms at the end of a
workout because the resistance is constant. If a low cable pulley set-up is not
handy, dumbbells can be substituted.
the forearms is not on the top of anyone's exercise to do list but
it it can be important. Strengthening the forearms can help improve grip and
when you have a strong grip, you will become more efficient at performing
most pulling exercises from pull-ups
dead lifts. In addition to the grip strengthening effect, the cable
forearms killer does a great job at 'pumping up' the entire forearms
musculature which if added at the end of a workout could also help you build
the size of your forearms.
