Many of us with larger butts, thighs &/or hips don't want the jiggle on display in spandex type clothing, but we need the chafe protection that this type of clothing offers since it doesn't ride up. Athletic skirts with compression shorts underneath are awesome once you find the right ones. Your jiggly bits are covered, you are chafe-free and your workout outfit is cute as heck too!
They make a nice reward when you hit goals too. More cute workout clothes to keep you motivated!
if you have thigh rub, check out skirts with a 5 in inseam underneath. Skirted capris & tights are available too. Fave brand = Skirtsports ($ but worth it). Gym Girl Ultra or Happy Girl work well for many. skirtsports.com
