A big bust is no reason to avoid exercise. Just try donning a Jubralee ($54; movingcomfort.com), the first sports bra developed and tested in Moving Comfort’s new in-house biomechanics lab. Designed to support B-E cups during high-impact exercise, Jubralee features hidden side and under-breast support and adjustable straps that minimize potentially painful up-down, in-out and side-to-side movement.
