From Pilates to half-marathons. Five sports bras ranked across all impact levels, with US and UK sizing notes (because bra sizing diverges most between markets).
Quick verdict: Gymshark Vital for daily light/medium use. Lululemon Energy for the best mid-impact crossover. Nike Alpha or Brooks Dare Crossback for serious high-impact running. Sweaty Betty Power Bra for the UK-loyal premium pick.
Gymshark · Daily wear
Cult sports bra of TikTok. Seamless ribbed knit doesn't chafe, ribbed support keeps things in place through HIIT and weights, cropped silhouette doubles as streetwear.
Lululemon · Mid-impact
The Lululemon mid-impact crossover — supportive enough for HIIT and short runs, comfortable enough for yoga. Adjustable straps, removable padding.
Brooks · High impact running
The serious-runner sports bra. Encapsulated cups (rather than compression), six-bra-strap rear, proper running support without strapping you in. Worth the price for runners over 5K.
Sweaty Betty · UK premium
British brand, mostly retail-distributed but available on Amazon UK. Strong cup support, removable padding, the premium UK pick that doesn't ape American athleisure aesthetics.
