Just curious - those who have a desk job, have you had struggles with flexibility and core strength? What has worked for you in addressing this? Has it made any difference in your bike fit or riding experience?

EXAMPLE: When I first started commuting, I thought my 23" frame w/ drop bars was too big for me (at 6' tall), at first even fitting a hi-rise 60mm stem and riding on the bar tops, bars level-ish with saddle. I was in pain pretty much constantly and would gas out after much over 10-12 miles. After yoga, squats, correcting seated and standing posture and building a standing desk for work, I am comfortable on the hoods and in the drops on that frame now with a 3 1/2" saddle to bar drop and 130mm stem. Not quite a year between then and now, about 3,500 total miles, most of them on that bike. I'm not an athlete and never was, and am mostly inactive off the bike. I only turned to those things to help keep me on the bike. The changes I made were casual and gradual. I still have core strength and flex issues, but they're getting better slowly with time.
