The UPPER category focuses on the arm & shoulder muscles or the upper body. There’s a healthy mix of push & pull exercises. Pushing moves stress the chest, triceps & front shoulders more. Pulling drills target the back, biceps & rear shoulders more. Try to do an equal amount of exercises in each category for training balance. If there’s a weakness in a given category, double or triple up on those drills. Most people could benefit from more pulling exercises.
