You've put some work in at a gym or at home to improve your appearance: suddenly you have the confidence to show off the results, getting shirtless without embarassment. You may even have started posting shirtless images of yourself on social media. You may even have booked a session with a photographer! Good for you, for recognising the value of fitness and improving your body image. Here we recognise such things! Some of these images also make the point that you do not have to be a muscle god to look good - although some have obviously been focussed on their bench presses and situps!
