According to LoveToKnow, there is no specific number of push-ups that will result in toned arms. The number required depends on an individual’s level of fitness and overall lifestyle choices.
Push-ups are efficient in working the biceps, triceps and shoulders. According to the Huffington Post, focusing on upper body exercises for these groups of muscles is a proper workout regiment for toned arms.
The Huffington Post suggests that to be most effective, any toning exercises should be completed three to four times a week and should alternate with aerobic exercises. Such a workout routine will strengthen the muscles without adding to their overall size.
