Another update... two months ago I said I could get from a dead hang to maybe 60 degrees, now I can get from a deadhang to 90 degrees. For some reason I can't get from 90 to the actual pullup, even though I can do a pullup starting at 90 degrees... so more practice.
I can do one pullup with just one band--which is supposed to offer 60 lbs of support, but on the bottom instead of the top, so it's pretty much the lowest level of support for the thing I can use. But I can only do one pullup at that setting. And since I'm doing Joel's program and doing pullups at tempo I need to have more support.
Getting there! Slowly but surely.
