The Best Online Shopping Sites for Active Wear

If you're looking to step up your workout game, you'll want to be properly outfitted with the right clothing, shoes, and accessories. Good workout clothes are built to move with you and stay comfortable as you exert yourself — and they can genuinely boost your confidence walking into the gym. Here's an honest look at where to shop for activewear online, and what each option does well.

East Hills Casuals

We'll start with our own, since we know it best. We stock activewear built for real bodies and real workouts — leggings with real stretch, sports bras with genuine support, yoga pants, joggers, and matching sets.

What we care most about is that our sizing runs through plus without treating it as an afterthought — the same styles, the same prices, cut properly rather than scaled up from a straight size. If you've been frustrated by activewear that fits everywhere except the hip and thigh, that's the problem we're trying to solve. Free shipping on orders over $50 and easy 30-day returns, so trying a fit costs you nothing. Check the size guide before you order.

Nike

Nike is popular with a wide variety of women thanks to their focus on athletic performance gear. Beyond standard t-shirts and shorts, they carry yoga apparel, running gear, and cycling pieces, much of it in breathable technical fabrics designed to keep you cool through intense workouts. Their range of prints and colorways is extensive.

Worth knowing: sizing varies between products, so check their size guide carefully, and plus-size options are more limited than their straight-size range. If you're buying compression pieces, look for breathable fabric rather than heavy spandex.

A general tip that applies wherever you shop: measure yourself first thing in the morning when your muscles are relaxed, and always check measurements against the specific brand's chart rather than assuming your usual size.

Old Navy

Old Navy has a solid budget selection of leggings, sports bras, and tanks, and they do carry plus sizes. Prices are reasonable and there's decent style variety. As with any budget activewear, quality can vary between lines — buy online and use returns to your advantage rather than committing to several pieces at once.

Amazon

Amazon's advantage is breadth and its try-before-you-buy program, which lets you order several items, keep what fits, and return the rest. Useful when you genuinely don't know your size in a brand.

The trade-off is quality control: with thousands of sellers, consistency is unpredictable and reviews are the only real signal. Read them carefully, especially on fit.

Lululemon

Lululemon sits at the premium end and has earned its reputation for fabric quality and durability — pieces genuinely last. Physical locations make it easy to try things on, which matters for technical fits.

The obvious consideration is price. If you're building a full activewear wardrobe rather than buying one hero piece, the cost adds up quickly.

How to choose

• Buying on a budget? Old Navy and our own activewear range both sit in a comfortable price band.
• Need reliable plus sizing? This is where most big brands fall short — look for retailers that grade properly across the full size run rather than stretching straight sizes.
• Want premium technical fabric? Lululemon, and expect to pay for it.
• Don't know your size? Order from somewhere with free returns and try two sizes.
