Why am I bent?
Stand in front of a mirror and look at your feet, legs, hips, arms, etc. Chances are one arch is higher than the other, each leg/knee has a unique shape, your finger-tips hang at different lengths, one shoulder is forward, etc.
Most imbalances/formations have counterparts to maintain function and a sense of balance in bipedal activities – standing, walking, running. These can be exacerbated or reduced by unilateral functions like racquet sports, golf, using the computer mouse, physical therapy, etc.
Imbalances become a liability when subject to the fixed-symmetry of a bicycle.
For example, a low arch and/or bowed leg can increase same-side distance between saddle and pedal and hand pressure. I might alter this effect by placing the appropriate sized shim or wedge under the short side shoe.
Correcting imbalances involves modifying the bike – saddle, bars, geometry, shoe, pedal, etc. – to fit the person, with a baseline established by proper weight distribution longitudinally, and between hands, feet, and Pelvis.
My experience is that a positive outcome occurs near the point that the spine ascends vertically from the sacrum towards the head, with equal vertebral translation and rotation through T-9. It is a bit more complex than just having your head above your butt because unilateral curvature can create contralateral muscle imbalances host to any number of other symptoms.
Imbalances are best addressed directly with a qualified fitter.
