What is the consequence of positioning the bike saddle forward in terms of rectus work?

Positioning the bike saddle forward can lead to greater work on the rectus abdominal muscles. When the saddle is moved forward, it often results in an altered body position that requires the core muscles, including the rectus abdominis, to engage more actively to stabilize the torso against the forward lean. This increased engagement comes from the need to support the upper body and maintain balance while pedaling efficiently. As the core is more involved in maintaining posture and stability, this arrangement prompts a higher demand on the rectus, leading to greater muscle work during cycling activities.

Therefore, the consequence of having the bike saddle in a forward position translates to increased activity and workload on the rectus muscles due to their role in providing stability and support in a more dynamic cycling posture.
