At E cup, compression alone stops controlling movement — the bust needs to be held in structured, separated cups. This is where encapsulated sports bras become the sensible default, and where the crop-top styles from mainstream activewear brands begin to fall short.
Matching the bra to the activity
High-impact styles — running, HIIT and jump-based training — use rigid encapsulated cups and a firm band; medium-impact styles suit the gym, cycling and reformer; wirefree and low-impact styles work for yoga, walking and rest days. At E cup the band does most of the work, so it should feel firm — if the straps are taking the load, the band is too loose.
