After finishing the main storyline of the Citadel DLC, you get the option to invite certain crewmembers up to your apartment for a scene. When you invite James in, he notices your exercise equipment as he's leaving. At this point, you can interact with the pull-up bar and he'll challenge you to beat his record – 182 pull-ups.
You can indeed manually do these pull-ups one-by-one. Is there any point or reward to completing this?

Well, I actually did them all. There is no material reward or achievement that I could discern for finishing - James was pretty impressed with me, though, so there might be dialogue impacts somewhere down the line. I might note that I did this before throwing the party and he didn't mention it at any point.
(For the record, even though it uses paragon/renegade prompts to step you through the motions, your reputation scores do not change. Also it took probably at least 15 minutes...)
