Best Maternity Activewear

The short answer

Staying active, briefly

ACOG and the NHS both encourage staying active through pregnancy, and the usual framing is to continue what you were already doing, moderated, rather than taking up something new and strenuous. What is appropriate for you depends on your pregnancy and your own provider's advice.

The standard advice to stop and seek advice applies: vaginal bleeding, regular painful contractions, fluid leaking, dizziness or feeling faint, chest pain, calf pain or swelling, headache, or muscle weakness affecting balance all mean stopping and contacting your provider.

Why the bra is the piece that matters

Breast size and tenderness both change substantially in pregnancy, and the bra you exercised in last year is almost certainly wrong now. An unsupported or badly fitting bra makes movement uncomfortable in a way that no amount of good leggings compensates for, and it is the single most common reason people stop exercising earlier than they needed to.

What to look for: band-and-cup sizing rather than S/M/L if you are above a D cup, a snug band (the band does the work, not the straps), and enough stretch to tolerate your size changing again. If you buy one around 36 weeks, a clip-down style means it also works for nursing. See maternity bras.

The two things that go wrong with everything else

The top rides up. Ordinary tops are not cut long enough to cover a bump when you raise your arms, and you spend the session pulling them down. Long ribbed tanks solve it cheaply; one-pieces solve it entirely.

The waistband slides down. Under-bump waistbands in particular, once the bump has weight. Over-belly panels with a high rise resist it, and technical fabric resists it better than brushed loungewear.

That is the argument for one-piece activewear, which eliminates both. The counterweight is real and worth saying: a jumpsuit has to come off entirely for a bathroom trip, and pregnancy involves a lot of bathroom trips.

Fabric: technical versus comfortable

Technical athletic knit wicks sweat, holds its shape and keeps its opacity through repeated washing. Brushed or ribbed loungewear fabric is softer, holds sweat, and bags at the knee sooner.

If you are exercising a few times a week, buy one technical pair rather than three brushed ones — the cost per wear ends up similar and the experience is substantially better. If you are walking, brushed fabric is fine and more pleasant.

Pregnancy makes you run hot, which tilts this further toward technical fabric in summer. See what to wear when pregnant in summer.

Support belts and exercise

Some people find a belly band helpful for running or impact work, where the bump moving independently is the complaint. If your issue is instead the pelvis feeling unstable — pain over the pubic bone or the dimples above your buttocks, worse on single-leg movements — a belly band will not help and a narrow pelvic belt might. See belly bands for running.

How we picked

Six axes: support, bump coverage, sweat management, whether it stays put while moving, size range and value per wear. Support and staying put are weighted hardest, because they are what determine whether a session is comfortable.

Note that the bra scores low on bump coverage and the tanks score low on support, which is correct rather than a flaw — these are pieces of a setup rather than alternatives to each other, and a single rubric across all of them shows that honestly.

We read the current listings and the reported experience; we have not worn these. The method is on how we pick.

Swimming is the other answer

Worth saying on an activewear page: swimming is the activity that stays comfortable longest in pregnancy, because the water takes your weight. If walking has become uncomfortable, that is often the next thing to try rather than giving up on exercise. See maternity swimsuits.
