I usually do my speed benching at the local chain gym, which only allows me to do straight weight. But the other day, I noticed they had a single pair of chains, which mostly just sit in one of the crates among the cable attachments. There's only one dude that uses them, and he just uses them for some weird shoulder raise. I guess he prefers the chain because he thinks it looks cool, since there's no real reason to do this with them otherwise.
Anyway, There are no little chains to actually fasten them to the barbell, so I'm not sure why they're there in the first place, but far be it from me to look a gift horse in the mouth. Just a quick trip to Home Depot, and I had a couple of small chains with clips ready to go.
Did my speed work with 185 plus the single set of chain. Normally I'd use more, but beggars can't be choosers.
Did 4 sets of 12 on the machine row, 4 sets of 15 on the dip machine, and 4 sets of 15 rope extensions and that was all.
