Even your bicep has two muscles so remember to concentrated on the individual muscles within a muscles group.
Many people will state that they worked their abs, chest, or legs on a particular day. But they may not have concentrated on the individual muscles within a muscles group (i.e. your quadriceps are not one muscle, but it is a group of four distinct muscles). Folland, et al. (2007) asserted that one strength training principle that competitive athletes focus on is training each individual muscle so that it is stimulated for maximum output potential. Therefore, make sure if you’re working your chest, do the bench press along with the incline press and pec flys to ensure each segment of the muscle is being stimulated.
