Going to the gym is more casual. You can also wear a vest with breathable and sweat-absorbing clothes, and it is best to wear loose sweatpants to sweat more smoothly and make your body more comfortable. It is more comfortable to choose sports shoes with soft soles.
Tennis is suitable for wearing soft-soled sports shoes, lower body shorts and upper body sports T-shirts. Because tennis is a more formal sport, it takes a lot of exercise and is easy to wear a vest, so a sports T-shirt suitable for sports is the best.
