I have a pretty solid “uniform” down for what I wear for workouts. If I’m running, I wear these shorts and one of these tech shirts. For BBG/HIIT workouts, I wear yoga pants and a tech shirt (or just a sports bra). For yoga classes, I like to wear crop tops and high waisted yoga pants.
Even with my favorites fully stocked, I can’t help but window shop. I used to be in the camp of not spending a lot of money on workout clothes, but now that I’m working out so much, I actually find that my clothes last so much longer when they’re higher quality. (And the quality is better for working out– they’re usually thicker and provide more coverage and don’t lose their elasticity.)
