I recently joined a gym to help my self get the over all workout that I need. However I am havin trouble finding the names of all the exercise machines in the logs. Two of them are both for the arms. The machines lable them as Arm Curl and Arm Extension. I'll post some pics I found on the web. Thanks for any and all help.
The first picture is kinda close to Preacher Curls as of body position, but preachers typically use a bent barbell, so I added a new listing of 'Machine Curls' in 'Biceps'.
The second picture I added 'Machine Extensions' under 'Triceps'
