Gym clothes that are too loose and don’t fit well are functionally worse to wear while working out.
Loose clothes will constrict your movement and make you look smaller than you are. If you’re a size ‘M,’ don’t wear ‘XL’ – you won’t look bigger and stronger.
Choose materials and a fit that gives you freedom of movement. A small percentage of spandex allows for a greater range of motion during exercise and provides a very comfortable fit without being too tight.
Clothing that is a little more fitted will also give you a more aesthetic appeal.
