Tyrannosaurus Rex Forearms

Digging holes is the best forearm workout in the world. Hits every angle you could imagine. I know that's not a practical exercise to work in your routine, but there is nothing like shoveling dirt around.

Ive done the roll ups before Dath mentioned. That's worked out the best for me in the gym. You can get the most range of motion from that forearm exercise. Roll up, roll down.

Try forearms curls (overgrip and undergrip)

Currently I am doing a low volume training thus I choose exercises that hit biceps and forearms.
Reverse grip bb biceps curls on week 1 and Pin wheel db curls on week 2.
IMO pin wheel curls work very well for forearms I get insane pump just after 3 very quick sets (2 light warm-ups 10-12 reps, 1 working set with 10 reps + 3 forced negatives)

One I used to do and have seen baseball catchers do...is a small bar or pipe with a rope attached to it long enough so when held straight out in front of you ( arms parellel to ground) a small amount of weight 10-15lbs can be hooked on the end but not touch the ground .. You then began to roll the bar and twist the rope up (like a fishing reel) all the way to the top and then lower it back down all at an even pace. You'll get such a burn and see lil veins you didn't know exaisted POP out.

This is one of those "classic" forearm exercises ( http://anabolicsteroidforums.com/#). Any have any experiences with this? Did it once or twice in some gyms I've passed through for a week, and all I remember is an insane burn.

I liked it a lot - watching people trying to figure out how to use was priceless. Sadly my new gym dont have that equipment.
I used to do it at the end back biceps session. 8-10 kg on the string, 3 sets of 4 rolling exercises (overgrip: roling it, roling out. undegrip: roilling in, roilling out)
Also very good forearm exercise in my book - my forearms always were sore on the next day, not to mention the post workout cramps.

My forearms never really developed until I quit using straps for 90% of my lifts on backday. I just use them on pullups because the bar at my gym in super small and hard to hold onto.

Thanks for all the input fellas! I can already feel a difference. I also built myself a small torture device for my gym based on one of the suggestions about the rope and bar out in front of you...I finish with this thing and cant use my fingers for about 15 minutes after I'm done.
