Why stop at 102 sets? If more is better, why not do 500 sets? Or 1000?
I did, out of sheer desperation, and a measure of stupidity give Poliquin's One-day Arm cure a try. Not because of any sound reasoning on his part or any particular faith I had in him--actually I'm closer to being in the HIT camp and think most "experts" are full of shit--but simply because I figured it was only one day of my life. Why not try it?
If you're not familiar with the program, it consists of doing a very brief arm workout lasting about 7-8minutes every half-hour for about eight or nine hours. I actually did it at a commercial gym, following his dictates to the letter, and was rewarded with a 1/4" of growth as a result. Whether that was worth the time is debatable. And I can tell you from experience that after 5 hours straight at a gym, it certainly didn't seem worth it.
Generally, if you're arms do lack in development I would suggest that rather than increasing your direct arm work you decrease it. Focus your efforts on heavy dips and chins and maybe a few sets of curls now and again, and I think you'll see far more growth than if you sit around doing 100 half-assed sets.
And there is always the Arthur Jones arm-cure:
1 60s chin, followed immediately by
Standing Curls to failure
1 60s dip, followed immediately by
Tricep Pressdowns to failure
Do this 1-2x a week for a couple of weeks and see what happens.
