Final answer:
Knuckle push-ups or using push-up handles are efficient variations for individuals with wrist mobility issues as they allow more elbow flexion without straining the wrists by keeping them in a neutral position.
Step-by-step explanation:
For individuals with limited mobility of the wrist, a push-up variation that allows for more elbow flexion without putting strain on the wrist is the knuckle push-up. In this variation, the individual makes fists with both hands and uses the knuckles as the point of contact with the ground, which keeps the wrist joint straight and reduces the need for wrist flexion and extension. Another alternative is push-ups with push-up handles or grips, which also keep the wrists in a neutral position and can help distribute the weight more evenly, minimizing the stress on the wrists. Both of these options engage the forearm muscles, namely the biceps brachii, brachialis, and brachioradialis, which are responsible for flexing the forearm, and allow for elbow flexion similar to traditional push-ups while reducing wrist discomfort.
