How to start a fitness clothing line with Print On Demand

Launching a sportswear brand follows the same process as launching any other brand. You need to find an idea that fills a market gap and sell it to your customer niche.

First, examine the current market situation. Conducting relevant industry research will help you find your customer niche and learn about current sportswear fashion trends and bestselling products.

Use Google Trends to explore what’s in demand in different parts of the world, or grab some ideas from the suggestions below.

eSports. Competitive multiplayer gaming events have surged in popularity, amounting to an audience of over 540 million people.

This means more people want to purchase eSports-themed fashion apparel. We’re talking shirts, hoodies, leggings, socks, and more, whether it’s in support of a specific team or game.

The industry’s global market revenue is valued at $2.39 billion.

Yoga. One in six Americans practice yoga, so this is your sign to start an athletic clothing business in this niche.

Top items to sell to yoga enthusiasts include leggings, socks, tank tops, and mats.

Experts project the value of the yoga industry to reach $215 billion by 2025.

Home Gym. With 35% of Americans working remotely or in hybrid setups, many adapt their workout routines for home.

A yoga mat near their desk, sneakers for morning runs, or a dedicated gym space – the sky’s the limit for selling gym clothing and accessories.

The global sports apparel market is set to reach around $245 billion in 2026.

Athleisure or Activewear. Your athletic apparel business doesn’t need to focus on just one product type – work out your areas of expertise for maximum profitability.

Create buyer personas to set your gym clothing line up for success and cater items to your target customers, whether they’re fitness enthusiasts or casual athleisure fans.

Choose what products to sell

When learning how to start a gym clothing line, understand that you’re stepping into a saturated market. Choosing the best clothing products and accessories is one way to stand out against competitors.

You’ll find the best selection of customizable activewear products in the Printify Catalog.

Here are four product categories and some top picks from our Catalog to help you carve out your niche.

Prepare a business strategy

Understanding how to start an activewear brand requires a well-thought-out business plan, from product creation to marketing.

After identifying the industry and target market, review your budget. Will you have enough money to cover start-up costs, or will you need financial assistance?

Consider opening a business bank account to separate your personal finances from your business. This is often a requirement when applying for business loans, business licenses, and business insurance, and will make your store accounting and tax filing much easier.

Next, decide your profit margin with all the associated expenses of your new business in mind. These include product fulfillment and shipping costs, taxes, and other expenses from your chosen sales platform.

Develop a brand

The next step in how to start an athletic clothing brand is crafting a business name. Carefully develop your fitness brand identity and establish your unique selling point to the target audience.

  • What’s your purpose? What will make your new fitness clothing line different from all other sports clothing businesses?
  • What are your brand values? If you support an important cause, communicate it clearly on your About page so customers understand what you’re all about.

Next, start working on the visuals for your gym apparel line. This includes the product designs, brand logo, and the appearance of your online store.

Select a marketplace or platform to sell on

It’s important to meet your target customers where they are to ease their shopping experience. Selling online is the best way to start for maximum flexibility and reach, although you can eventually expand to a physical storefront.

Understanding the difference between an eCommerce platform and a marketplace is crucial when launching your own fitness clothing line.

An eCommerce platform lets you build a custom online store, giving you complete control over branding and the shopping experience. A marketplace is where many sellers offer their products, providing an existing audience but less control over customization.

Here are some popular online eCommerce solutions we recommend.

  • Shopify – Perfect for creating a stand-alone, fully customizable online store. Shopify’s apps and integrations are convenient for building a streamlined shopping experience.
  • Etsy – Known for unique items, this marketplace provides excellent exposure to an established customer base. It’s ideal for independent designers and beginners selling POD products.
  • Wix – An easy-to-use website builder with strong eCommerce capabilities, offering a balance of simplicity and customization for your fitness POD store.

Each solution offers different features and audiences for your fitness apparel business. You don’t have to choose just one – connect multiple platforms to the same Printify account.

We offer the Printify API and automated integrations with some of the most popular eCommerce platforms and marketplaces. For example – Shopify, Etsy, Wix, TikTok Shop, WooCommerce, eBay, and more.

Save up to 30% on shipping costs when ordering products for your fitness apparel line in bulk. It’s a cost-effective way to supply physical stores or local markets.

Prepare a marketing strategy

Your fitness clothing business marketing strategy should adapt to each marketing channel you’re using.

Whether crafting engaging fitness lifestyle posts for Instagram or making TikTok videos, make sure to:

  • Keep up with trends to create relevant content for your audience.
  • Run ads for better visibility.
  • Use each platform’s marketing tools to grow your fitness clothing business.
  • Optimize your eCommerce shop for search engines.
  • Link your online store to major social media platforms.

Focus on the tools and strategies that work best for each platform to connect with your audience.

Collect data and adapt

Regularly analyze data to stay ahead of the competition and adapt to market trends.

Monitoring trends in clothing manufacturing, following fitness influencers, and studying your competitors are all key activities that can inform your business decisions.

Good data collection helps your fitness apparel business meet customer expectations and address their needs.

Understanding their preferences and shopping behaviors lets you create a product line that resonates, making it easier for consumers to see themselves wearing and enjoying your fitness clothing.

Maintaining steady business growth when starting a fitness clothing brand involves developing a solid business plan and successfully adapting to market demands.

Increase your chances of success in the fashion industry by following these additional tips to help your business idea thrive.

1. Market in the right places

Consider multiple marketing channels to reach potential clients, but only stick with ones that provide a return on your investment. Weigh these factors to make an informed decision:

  • Where do your customers spend most of their time?
  • Which social media platforms do they use?
  • What types of media do they consume?

Advertise your business website through these channels to gain the most reach for your new fitness clothing line.

Quick tip

Remember to keep track of your advertising expenses and metrics as part of your overall marketing plan to ensure your ads bring in new and returning customers.

2. Automate repetitive tasks

Save time and increase your productivity by automating key features of POD and eCommerce platforms.

Connect your Printify account to a sales channel to quickly manage product listings. We also provide order fulfillment automation – our activewear manufacturers will print, package, and dispatch products for you.

Some other aspects to consider automating are ads, email campaigns, and customer relationship management (CRM).

3. Expand your product selection

Once you start selling athletic wear, customers will provide feedback on which sports clothing products they like and want to see featured in your store.

This is all valuable information that will help you expand the offerings of your private-label fitness clothing line by adapting to customers’ needs and requests.

4. Be one step ahead

Having a solid business plan is just the beginning. To stay competitive, keep an eye on trends like: 

  • Customers’ spending habits 
  • Competitors’ products and strategies
  • New items with a high profit potential 

These are all crucial aspects of running a successful fitness clothing line.

The trends you follow will depend on the type of fitness line you have, but make sure to capitalize on opportunities before they go mainstream. Whether it’s men’s leggings or innovative sports bras, keep your store stocked with potential bestsellers.
