Someone created a male version of the Dove Evolution video. It starts at :54 seconds or so. The first little bit is about why the video was created.
Beauty isn’t in how defined your abs are. How big your biceps are. How much muscle is on your body. Those are subjective, inconsistent measures of what it means to be a man and what it means to be beautiful.
Being yourself is the most beautiful thing. Love your body as it is. Be comfortable in the skin you’re in.
