Hi Doom,
no I dont, no belts.
I use an Inzer like Frank mentioned though mine was bought before the levers came out. I'd probably still be using my first belt if it hadnt shrunk

There are many different types of shrugs, and of course your goals should determine which kind you do. I have always liked doing olympic lifter type shrugs for building explosive strength that will transfer to my deadlift. These are done by:
-stand straight with the bar with an overhand grip(use straps if needed)
-slowly lower the bar to just about the top of the knees(remember to keep back flat or
arched and head straight)
-at the same time in one explosive motion shrug the bar up as high as you can while
going up on your toes. Visualize touching your ears with your traps. You cant but
it's a good focus.
-lower the bar slowly again and repeat
Cautions:
-make sure not to bend your arms, they should actually hang and be relaxed as is
possible while shrugging a heavy weight. At the 1987 YMCA Nationals in
Columbus,Ohio I tore my right bicep muscle in half bending my arm with a relatively light
opening deadlift attempt of 710. It was not a fun time.
-if you try this style please practice form very light for at least the first few weeks.
I really dont want to be responsible for someone hurting their back.
-warm up thoroughly before your heavy sets. I can shrug more than I can deadlift
but I always start with 135 or 225 and work my way up. It will prevent
injuries and help you find your groove and form for the exercise.
-if you wear sweatpants, this one will wear holes in them very quickly.
Cant stress enough how important it is to strengthen the stabilizer muscles, abs,obliques,low back to prevent shrug injuries. Ice on the lower back after a deadlift or shrug workout for no longer than 15-20 minutes will promote faster healing.
Being a competitive powerlifter every exercise I do is geared towards improving the 3 powerlifts but the same ideas and precautions should work whatever your goals are.
BTW, if you could only do one exercise to help improve your deadlift, shrugs are not the best choice. Heavy power style bentover rows will yield much better results if done right.
