One of the best things I ever did for myself and for the comfort of my workouts (thereby making them more likely to stick to), is to start buying the kind of lightweight materials that are out now, a lot of them by exclusively fitness clothes companies. There are quite a few actually at Target, with their store brand of workout and active clothes, and that’s actually where I got my first piece of lightweight, breathable clothing for the gym (or at home, whether you work out there or at a gym).
These are usually some sort of meshy sort of material, but not always. They actually allow the skin to breath because the weave is so light. They also help to wick away sweat from the skin, and help to prevent acne and irritation bumps on the back and chest due to irritation from sweating and the intense body heat that builds up when you work out hard.
I’ve also found some great workout clothes that are made with this type of material, which unfortunately does cost you a little more than just plain old cotton, at some outlet stores by us. For instance, there is a boatload of light workout clothes at the Reebok and Adidas and Nike outlet stores near our house, all at a substantial discount. And the best part is, you are still buying a great, durable brand, you’re just usually getting it at a substantially lower cost.
I bought a few sleeveless shirts that are a light heather grey, and they are really a pleasure to work out in. Their price was also a pleasure, marked down to just ten bucks each, and they wash great too, they don’t even shrink. Do yourself a favor, if you’re being cheap and just want to wear your old tshirts to the gym, at least go out and buy yourself one or two good light breathable shirts, and you’ll see the difference. Soon, you’ll be a convert!
