Uncontrolled type 2 diabetes stripped my weight down from 185 to 160 in about 3 months... which now at 5' 10" is ok, but I lost a LOT of muscle mass in the last month of that process, and propelled me into seeking medical attention. In the last 4 months, with my blood sugar under control, it's dropped as low as 157(which made me nervous because it was unintended) and only up to 161.
I would like to (best case) trade 12 lbs. of fat for 6 lbs. of muscle by the end of spring. Half of that would still be a win, in my book. No idea what that would translate to, on the bike.
At my peak fitness, (as a Jr.) I was 5'10 3/4" 153lbs. My resting HR was 49 and I probably had a BMI around 10-12. We weren't yet obsessed with losing every lb. we could off our bodies, just our bikes... Funny
