If you'll reading along you might notice the Chin Up experiment that's going on.  Its a kind of a bastardized Easy Strength Ladder combine.  I started out with 25# and 3-2-1 went to 25# and 5-4-3-2-1 then 35# and the same rep scheme.  Next I'm going to try 50# and see how that goes - it's a 5# bigger jump and may need fudged a little bit.  It should finish up just before vacation and it will be time for a break anyway.  Figure I'll see how far I can take it when I come back.  Long term I'd kind of like 5 to eight reps with 50 to 60 # maybe when I'm 70?  We'll see.
