I don’t think so.
You can’t wear yoga pants, sweat pants, or leggings and *most* activewear pretty much falls under one of those categories.

Try something like golf pants. They look professional, and are good active wear. You should be able to get Ben Hogan brand (in mens) at Walmart, it's not too pricy. For women's pants, try Academy, or other similar sporting goods stores, or just look online. I really like Dickie's brand work pants as well.

You can’t really wear active wear pants. They have to be slacks/jeans. Anything like joggers, sweatpants, leggings aren’t allowed.
