Exercise Advice: Spider curls are very similar
to preacher curls except that you they allow you a much greater
range of motion throughout the exercise. Using a regular preacher
bench, grab an EZ Curl bar (or regular barbell) and simply rest
your elbows on the opposite side of the preacher pad allowing your
arms to hang straight down. Next, execute the movement just like
you would a regular preacher curl. Slowly return to the start position
and repeat.
