Thinking about splurging on high-end workout gear? Experts say it might not be worth it. While specialized fitness clothes can be helpful, they’re not essential for staying active.

“If you’re just starting out or exercising for fun, you don’t need to rush out and buy expensive gear,” says a clinical exercise physiologist. The main thing to focus on? Comfort. Clothes should fit well—not too tight or too loose—and feel good during movement.

Weather also plays a big role in what you wear, especially if you’re exercising outdoors. Cotton might seem like a safe choice, but it’s not ideal for workouts. It soaks up sweat and clings to your skin, which can make you overheat in summer or risk frostbite in winter. Instead, opt for synthetic fabrics that let air flow and keep moisture away.

Shoes are another key factor. While activity-specific shoes can be helpful, a good all-purpose pair will do the trick. Just make sure they’re broken in, supportive, and leave room for your toes to move.

For those diving deep into a fitness routine, investing in a few quality pieces can boost performance and confidence. Tight-fitting leggings or shirts can make activities like running or tennis more comfortable. And for women, a high-impact sports bra can make a big difference in both comfort and performance.

But experts warn about sportswear containing bisphenol A (BPA), a chemical found in some athletic clothes. BPA can harm health if absorbed through the skin, so it’s smart to remove sweaty workout gear right after exercising and avoid polyester with spandex.

At the end of the day, the best workout outfit is one that feels good and fits your budget. “Pricey doesn’t always mean better,” says a fitness coach. “If you’re comfortable and confident, your clothes are doing their job.”

So, whether you’re rocking baggy sweats or high-tech leggings, the most important thing is to keep moving.
