It's like overclocking but better: every chip [human] has a different limit! Also makes for a great stress reliever.
I'm also seriously considering joining MIT's powerlifting team, because according to stats on MIT's powerlifting team (I dream of steel), I'm pretty close to benching competitively (but seriously need to work on squatting and deadlifting), I've never joined a legitimate sports team (math team doesn't count), and…#yolo.
In somewhat related news, I started using Fitocracy to track my progress! It's a cute webapp that I've been trying to replicate for the past ~half year or so, but never got around to implementing it.
