I get that too and I probably don't bike nearly as much as you.  I do about 70 miles a week at most lately.  That's nothing, and it's even less than I was doing before, but I'm trying to keep exercise to a minimum lately because I'm actually worried about getting too lean (I refuse to eat fatty foods and I have to avoid straining an injury, so I can't strength train right now and it's driving me crazy). Crabs in a bucket.  If I get spotted on a bike only 5 miles from my house by one of my many fat neighbors, I'll get a speech about how I'm "pushing it too hard".  Jealous fucking children is what they are.  It doesn't matter how much exercise you are or aren't doing.  If you're "too skinny" for their selfish ego to handle, they'll passive-aggressively try to sabotage you.  Fuck 'em.
