Played with the globs(irregular but basically round heads of old york globed DB's) that I bought from Brent today. Did some holds, cleans, lifted them in all sorts of different positions. Lifting these things REALLY worked my R&P well. I didn't really pay attention to what I was doing so I can't write down repsxsets and such but it lasted almost 4 dragonforce songs so it must've been a good 15-20 minutes.
I also did 30 assisted lifts with my Blob50 and with my fatman 45 blob. Then proceeded to do at least a dozen negatives with my slick 40lb blob and a handful of lifts of the 32.5 blob.
