Cycling holds the hip closed, the upper back rounded and the neck extended to look up the road, for as long as you ride. If you then sit at a desk, the day is essentially one shape with two variations. The work that helps cyclists is therefore mostly the opposite of the riding position: hip extension, thoracic extension and rotation, and neck and shoulder release.
Note that hamstring stretching, which cyclists are usually told to do, is not top of that list.
What the position does
Hips stay closed. You never extend the hip fully on a bike. The pedal stroke works through a limited range. Hours of that, plus a desk, and hip extension quietly disappears.
The upper back rounds. Reaching for the bars puts the thoracic spine into flexion and holds it there. On a road bike with any drop, considerably so.
The neck extends to compensate. To see where you are going while your upper back is rounded, the neck has to extend. This is the source of a large share of cyclists' neck complaints, and it is why working on the neck alone rarely fixes it.
Shoulders take load and internally rotate. Weight through the hands for hours, shoulders creeping forward.
Glutes work in a narrow range and hip flexors stay short. The combination that most often shows up later as lower back ache on longer rides.
What actually helps
Hip flexor length, tailbone tucked. The single highest-value thing, and the one most people do with their pelvis in the wrong position so they feel it in the lower back instead.
Thoracic extension and rotation. Over a foam roller, or kneeling with hands on a chair and letting the chest drop, or seated rotations. Two or three minutes changes how the neck feels on the next ride more reliably than anything done to the neck.
Chest and front-of-shoulder length. Doorway stretches, or a supported shape lying over a rolled towel along the spine.
Glute strength through a full range. Bridges, lunges, step-ups. The pedal stroke does not train the glute at length, and the lower back ends up covering for it.
Neck, gently. Slow rotations and side bends, not forced. Most of the improvement here comes from the thoracic work above.
Hamstrings, lightly and last. They are usually tight from working rather than short, and aggressive stretching is a good way to irritate them.
After a ride, or after a commute
Twelve minutes, and it matters more after a long ride than at any other time.
Hip flexor length both sides, two minutes. Thoracic extension, two minutes. Chest opening, two minutes. A gentle twist lying down, two minutes. Legs up the wall, three minutes, better for tired legs than most of what people do instead. Then a minute of slow breathing.
If you commute by bike daily, this is more valuable than a weekly class, because it happens in the same frequency as the thing causing the problem.
Where a session helps
Two specific things. Getting the pelvis position right in hip flexor work, which is very hard to self-assess. And working out whether your neck complaint is a neck problem or a thoracic one, which determines whether the useful work is where you feel it or somewhere else entirely. Both are answered by someone watching you move for ten minutes.
Thirty-minute sessions suit cyclists well. The work is specific rather than general, and it does not need an hour.
Questions people ask
What should cyclists stretch?
Hip flexors and quads, the chest and front of the shoulders, and the thoracic spine, which all shorten or stiffen in the riding position. Hamstrings are usually tight from working rather than from being short, and are a lower priority than most cyclists assume.
Why does my neck hurt when cycling?
Usually because the upper back is rounded in the riding position, so the neck has to extend further to see the road. Working the thoracic spine into extension and rotation tends to help more than treating the neck directly, though a bike fit is also worth checking.
Does yoga help cycling performance?
Not directly in any well-evidenced way. It helps by keeping the ranges you need available, providing glute and single-leg work the pedal stroke does not, and making long rides less likely to be interrupted by back or neck discomfort.
When should I do it, before or after a ride?
After, or on a rest day, for anything involving long holds. Before a ride, keep it to a few minutes of active movement for hips and thoracic spine; long passive stretching immediately before is not useful.
