The arms are there only to support and balance the movement. In long distance running, weight is an integral factor. It will make a difference in performance, especially in events that resist ‘extra’ gravity, such as running up a hill or mountain. Weight can spell the difference between winning and losing, finishing and failing. Excess muscles from parts not used in running, such as most muscles in the arms are just useless burden.0Reply Share ShareShare on FacebookShare on TwitterShare on LinkedInShare on WhatsAppLeave an answerLeave an answerCancel replyConnect with: Featured image Select file Browse Save my name, email, and website in this browser for the next time I comment.
