SIZE GUIDE
STEP 1: GET PREPPED
Grab a non-wired and non-padded crop top or bralette and a tape measure, to get measuring.
STEP 2: YOUR UNDERBUST MEASUREMENT
Start with the underband: hold one end of the tape front and centre, directly underneath your boobs. Pull the tape around your back to meet the front.
STEP 3: YOUR BUST SIZE
Hold the tape measure at the center again but around the fullest part of your chest. Don't pull too tight, just secure enough that it doesn't droop.
STEP 4: CALCULATE
Now head to the fit calculator tab and enter your bust and underbust measurements to find your Gymshark sports bra size.

Your boobs get compressed into one uncomfortable mass - hello Uniboob!
No more compression—our patented X design provides sculpted support that lifts, shapes, and moves with you. Because true comfort means definition without restriction.
Your boobs get compressed into one uncomfortable mass, which ultimately leaves the rest of your torso temporarily indented - Ouch!
