Using metal cuffs for the back row machine is an excellent way to alleviate stress on the fingers, especially for those with sore fingers or arthritic conditions. These cuffs provide a secure grip without requiring the user to tightly grasp a handle, reducing strain on the hands. By distributing the weight more evenly across the wrists and forearms, metal cuffs enable a more comfortable and effective workout. This allows individuals to focus on engaging their back muscles fully without the discomfort or limitations caused by finger pain, enhancing both the quality and safety of their exercise routine.
