Quick answer
For core-engaging activities like yoga, Pilates, or martial arts, a firmer cup like MeLuna Sport is the best choice. Pick the size based on your flow and cervix height, not your activity level.
Why firmness matters for active use
Standard menstrual cups can collapse or leak during intense core engagement because softer silicone gives way under abdominal pressure. A firmer cup maintains its seal and shape, so you stay leak-free during crunches, horseback riding, or pole dancing.
The trade-off is that firmness can feel less comfortable for some users, especially if the cup presses against the bladder or cervix. The MeLuna Sport is 25% firmer than the Classic, which helps it pop open easily but may not suit everyone's sensitivity.
Size selection is about your body, not your sport
Your workout intensity doesn't dictate cup size—your menstrual flow and cervix height do. A cup that's too large can be uncomfortable or hard to insert, while one that's too small may leak on heavy days.
The MeLuna Sport comes in several sizes. The MEDIUM (product ID 2217708) is a good starting point for average flow and average cervix height. The XL (product ID 2217895) holds more volume and works better for heavy flow or a higher cervix.
How to choose your sport menstrual cup
- 1. Assess your flow: If your heaviest day requires changing every 4–6 hours, choose MEDIUM. If you need more capacity or have very heavy flow, choose XL. Check your pad or tampon usage to estimate volume.
- 2. Check your cervix height: On your heaviest day, insert a clean finger and feel for your cervix. If it's low (within a knuckle), MEDIUM is usually better. If it's high (beyond your second knuckle), XL provides the length needed to stay in place. A cup that's too long can poke or cause discomfort.
- 3. Decide on firmness comfort: The Sport is the firmest option. If you've never used a cup before or are sensitive to pressure, consider starting with a softer cup. If you've used cups and want a reliable seal for sports, the Sport is ideal. Firmness is a trade-off: better seal vs. potential discomfort.
