The shoulder and wrist muscles need to be stretched, as they are responsible for controlling and turning the bicycle. Most cyclists also tend to tense the muscles in their hands and shoulder, which can lead to aches and pains in those areas. The best way to stretch these muscles is to bring your arm up to a 90-degree angle from your body and reach over to the opposite side, using the other hand to lock it into position. Pull the arm in towards your body for 10 seconds, at which point you should feel the muscles on the side of your shoulder stretching. Repeat five times on each side.
With regard to the wrists, these can be stretched by holding your arm out in front of you, palm facing downwards, and using the other hand to pull your hand up and towards your body, holding the position for 10 seconds. Then, bend your hand over forward and once again use the other hand to pull your hand towards your body, holding the position while you count from 1 to 10. Repeat this stretch 10 times.
