Final answer:
Good riding posture includes aligning the center of gravity above the hips, positioning the upper body correctly over the pivots in the hips, and maintaining leg position to keep the body's center of gravity over the base of support.
Step-by-step explanation:
Three components of good riding posture are essential for maintaining balance and preventing strain. First, the rider should have their center of gravity directly above the hips. This not only stabilizes the rider but also prevents back strain by eliminating unnecessary muscle exertion to keep balance. Secondly, the upper body should be positioned correctly over the pivots in the hips, which optimizes the body's alignment and reduces the risk of injury. Lastly, maintaining the legs in an appropriate position to ensure the overall center of gravity of the body remains above the base of support, which in the context of riding would be the feet on the pedals or the floor.
