Gym Apparel Market Size and Growth Statistics
These market statistics track the money moving through gym apparel and where it is headed.
The global activewear market reached $345.79 billion in 2025 and is forecast to climb to $373.07 billion in 2026 on its way to $720.25 billion by 2034, a compound annual growth rate of 8.57%, Fortune Business Insights reported.
Apparel, not footwear or accessories, drives that market. The apparel product segment held 67.67% of the activewear market in 2026, the same report found.
North America is the anchor region. It accounted for 34.11% of the global activewear market in 2025, worth $117.95 billion, and the US market alone is projected to reach $100.53 billion by 2026.
That kind of demand is why the men's apparel category keeps expanding across performance and everyday lines.
Women's Activewear Statistics
Women are the single largest buyer group in gym apparel, and the numbers make the case plainly.
Women made up 60.45% of the activewear market in 2026, the largest end-user share, according to Fortune Business Insights. That share reflects both rising female sports participation and the crossover of activewear into daily wardrobes.
In the broader athleisure category, women held 46.38% of the market in 2026, per Fortune Business Insights, a near-even split that shows how much of the everyday-wear boom is being carried by women's lines.
The demand runs across tops, bottoms, and layers, from women's shirts and tops to a full range of women's apparel built for training.
Athleisure and Everyday Wear Statistics
Athleisure is the reason gym apparel no longer lives only in the gym, and it is growing faster than the core activewear market.
The global athleisure market was valued at $368.61 billion in 2025 and is projected to grow from $402.74 billion in 2026 to $844.77 billion by 2034, a compound annual growth rate of 9.7%, Fortune Business Insights found.
Online buying is central to how athleisure sells. E-commerce accounted for 44% of the athleisure market in 2025, the same report noted, well ahead of most traditional apparel categories.
North America led all regions with 37.04% of the athleisure market in 2025. The pull of training-inspired clothing that works for errands and offices keeps that number climbing, and it is why a training staple like a good men's t-shirt now doubles as everyday wear.
Leading Gym Apparel Brand Statistics
These brand statistics show how the biggest names in gym apparel are performing, straight from their own filings.
Nike remains the largest player. The company reported $46.3 billion in total revenue in fiscal 2025, with its apparel business alone generating $12.97 billion and footwear $29.51 billion, according to Nike.
Lululemon crossed a milestone. Full-year net revenue topped $10.6 billion in fiscal 2024, up 10% year over year, with international net revenue rising 34%, and the chain ended the year with 767 company-operated stores, per Lululemon.
Adidas posted strong growth too. Full-year 2024 revenue reached 23.68 billion euros, up 12% on a currency-neutral basis, adidas reported.
Apparel is the backbone of the specialists. It made up 67% of Under Armour's fiscal 2025 net revenue, ahead of footwear at 23% and accessories at 8%, according to Under Armour. The same lesson applies to the gear that supports heavy training, from apparel to lifting straps.
Gym Apparel Materials and Sustainability Statistics
What your gym clothes are made of is mostly one fiber, and that has real sustainability implications.
Global fiber production hit a record 132 million tonnes in 2024, up from 125 million tonnes in 2023, according to the Textile Exchange Materials Market Report.
Polyester dominates that mix. It made up 59% of global fiber production in 2024, about 78 million tonnes, and 88% of it was fossil-based, the same report found. Polyester's stretch, moisture handling, and durability make it the default for gym apparel.
The recycled share is still small. Recycled fibers accounted for just 7.6% of production in 2024, and recycled polyester made from plastic bottles, not from old textiles, made up 6.9% of all fiber produced worldwide. Less than 1% of the global fiber market came from recycled textiles, which shows how far the industry sits from a true circular loop.
Consumer Behavior and Resale Statistics
How people buy gym apparel is shifting, and secondhand is one of the clearest signals.
The US secondhand apparel market grew 14% in 2024, its strongest year since 2021 and roughly five times faster than the broader clothing retail market, according to thredUP. The US secondhand apparel market is expected to reach $74 billion by 2029.
Online resale is leading that charge, growing 23% in 2024. Activewear sits at the center of it, since the top resale brands are all athletic or outdoor names, led by Lululemon, Patagonia, and Vuori, the same report found. Durable gym apparel holds its value, which is exactly why it resells well.
Emerging Trends and What's New in 2026
A few themes stand out for anyone tracking gym apparel statistics this year.
Athleisure keeps outpacing core activewear, growing at 9.7% against 8.57%, per Fortune Business Insights. The line between training clothes and everyday clothes is effectively gone, and women's lines are carrying much of that shift with a 46.38% share of the athleisure market in 2026.
Resale is becoming a real channel, not a niche. With US secondhand apparel up 14% in 2024 and athletic brands topping the resale charts, per thredUP, durable gym apparel now has a proven second life that shapes how shoppers value it new.
Sustainability remains the industry's open question. Recycled fibers were still only 7.6% of global production in 2024 while polyester climbed to 59%, per Textile Exchange, so the gap between climate pledges and material reality is the story to watch.
E-commerce is now the default counter. With 44% of athleisure sold online in 2025, per Fortune Business Insights, the buying decision increasingly happens on a phone rather than in a store.
