Here’s an expensive lesson most of us learn the hard way: the cutest leggings on the rack are not always the best leggings for the gym.
Some go see-through when you squat. Some roll down every time you bend. Some pill after three washes.
So before you buy anything, it helps to know what to look for.
This list covers 25 must-try women’s gym outfits. For each one, you’ll get the key feature to check before buying and whether it’s worth spending more or saving.
Only buying one thing this season? Make it number 1. And if you want the best-value piece, number 8 is hard to beat.
The 30-second fitting room test
- Squat in front of the mirror. If you can see your underwear, it’s see-through.
- Jump a few times. Does the waistband stay put?
- Raise your arms. Does the top ride up too much?
- Check the seams. Flat seams rub less.
1. High-waisted leggings
Here’s the one piece worth investing in.
Good leggings are the foundation of every gym outfit. You’ll wear them more than anything else.
