The Boston Marathon Was My First Race — These Training Essentials Made All the Difference

OFFLINE By Aerie Real Me XTRA Hold Up! Lift Legging ($45, originally $75)

If we're being honest about insecurities — mine is how I look when I run. I want to look toned, athletic . . . and like my butt actually exists. "Look good, feel good" is real, and these butt-lifting leggings gave me the confidence boost I needed on some of my least motivated days. Bonus: the waistband is super comfortable and actually stays up while you're running. If you know, you know.
