The right threads
After shoes, clothing is your next big expense, especially if you’re a woman. Women’s workout apparel tends to cost more than men’s, and there’s more of it to buy -- women need sports bras to keep “the girls” in place, and they’re not cheap!
My suggestion is to head to T.J.Maxx, Target, Nordstrom Rack, or another discount store and grab marked-down pieces. Some online-deals sites, like The Clymb and zulily, also offer good deals on athletic apparel.
The thing is, there’s absolutely no reason you need to spend more than $20 on a shirt or pair of pants, and in many cases you can stock up for less than that. My suggestion is to budget about $100 to buy two complete outfits of very basic apparel: black shorts or yoga pants, a black or gray wicking T-shirt, and two great sports bras (if you’re a woman). You can always rotate in T-shirts and tops you already own to mix up your look, and by sticking with the basics, no one’s going to wonder why you keep wearing the same pair of shorts for every workout.
