What are the best tops to wear at the gym? The best gym tops are usually made from breathable, sweat-wicking fabrics that keep you cool and dry during training. They often feature ergonomic designs that allow for a good fit and don't restrict your range of movement. There is no specific type of top to wear to the gym, so long as you feel comfortable throughout your workout. Are gym tops meant to be tight? A gym top does not need to be tight, but a closer fit can provide benefits, such as preventing loose fabric getting in the way during your workout and helping to wick away sweat. Ultimately, you should wear a top that feels comfortable when you're exercising, and there is no requirement for a snug fit.
