Final answer:
Incline push-ups are the best option for individuals with limited wrist mobility because they reduce the necessary wrist extension and allow for greater elbow flexion.
Step-by-step explanation:
The push-up variation that allows for more elbow flexion for those with limited wrist mobility is the incline push-up. Incline push-ups are performed with the hands placed on an elevated surface. This modification reduces the angle between the arm and the body, as well as the amount of wrist extension required, compared to a standard push-up. Therefore, it can benefit those with wrist constraints or discomfort. In contrast, diamond push-ups are more intensive on wrist flexion and wide push-ups do not significantly alter wrist positioning. Decline push-ups place even more stress on the wrists, as they increase the load on the upper body.
