Day 508 of 100+ pushups per day; day 407 of 120+ pushups per day, sets breakdown: 4x36 normal/narrow; Total: 144 Bad habit? Tobacco. I don't know if I want to keep it forever, but for the vast majority of my life I've enjoyed the positive effects of the drug (that people rarely talk about): grounding, stimulative effect (both mentally and physically). It's possible that it is also largely responsible for the fact that I've never had any troubles with weight (if anything, a bit of a weight gain would probably do me well). All of the above also goes for caffeine (coffee and/or yerba mate, not your energy drinks or other synthetic stuff), but I guess that has a bit of a less of a stigma nowadays.
