What to Wear to the Gym – The Complete Women’s Guide

Heading to the gym for the first time — or just tired of wearing the wrong thing? You’re not alone. Knowing what to wear to the gym can feel confusing, especially with so many options out there. But the truth is, the right gym wear makes a real difference — to your comfort, your performance and your confidence.

In this complete guide, we’re covering everything you need to know about what to wear to the gym as a woman in 2025.

The Golden Rules of Gym Wear

Before we get into specifics, here are the golden rules every woman should follow when choosing what to wear to the gym:

• Comfort first — If you’re constantly adjusting your outfit, it’s distracting you from your workout.
• Function over fashion — That said, feeling good in what you wear genuinely boosts motivation. You don’t have to choose.
• Dress for your workout — What you wear to a yoga class is different from what you wear to a HIIT session or a run.
• Invest in quality — Cheap gym wear falls apart quickly. Quality activewear lasts longer and performs better.

What to Wear to the Gym: The Essentials

Sports Bra

A good sports bra is non-negotiable. It protects your body during exercise and keeps you comfortable throughout your workout. Match your sports bra to your activity level:

• Low impact (yoga, pilates, walking) — Light support, seamless crop top or bralette style
• Medium impact (gym training, cycling, HIIT) — Medium support with a secure band
• High impact (running, intense cardio) — Maximum support, minimal bounce

Our B|FIT XCELERATE Sport Bra and NOVA Sports Bra with Removable Padding are two of our most popular options for gym training.

Leggings or Shorts

The biggest decision most women face — leggings or shorts? Here’s a simple guide:

• Leggings — Best for yoga, pilates, leg day and cooler gyms. Look for high waist, squat-proof and four-way stretch.
• Shorts — Best for cardio, cycling, HIIT and warmer environments. Look for lightweight, quick-dry fabric.

Our bestselling B|FIT XCELERATE Leggings and B|Fit Q.D. Shorts cover both bases beautifully.

Gym Top

Your gym top should be breathable, comfortable and allow full freedom of movement. Options include:

• Crop top — Pairs perfectly with high-waist leggings. Great for the gym and yoga.
• Tank top — Lightweight and breathable. Ideal for cardio and HIIT.
• Long sleeve top — Great for cooler gyms, outdoor workouts or as a warm-up layer.

Trainers

Always wear appropriate footwear for your workout. The wrong shoes can cause injury and affect your performance:

• Cross-trainers — Versatile and great for general gym use, HIIT and classes.
• Running shoes — Designed for forward motion. Essential for running on the treadmill or outdoors.
• Flat-soled shoes — Better for heavy lifting like squats and deadlifts.

What to Wear for Different Gym Workouts

Weight Training & Strength

For lifting, you want freedom of movement without excess fabric getting in the way. Go for fitted leggings or shorts, a supportive sports bra and a breathable crop top or tank. Flat-soled trainers are best for heavy compound lifts.

HIIT & Cardio Classes

High-intensity workouts mean you’ll sweat — a lot. Prioritise moisture-wicking, breathable fabric that keeps you cool and dry. A supportive sports bra is essential, and lightweight shorts or fitted leggings work well.

Yoga & Pilates

Comfort and flexibility are everything for yoga and pilates. Seamless leggings with four-way stretch are ideal, paired with a light sports bra or crop top. Avoid anything too loose that might fall over your head during inversions.

Running (Treadmill or Outdoors)

For running, prioritise moisture-wicking fabric, a high-support sports bra and well-fitted leggings or shorts that won’t ride up. Reflective details are a bonus for outdoor running in low light.

Cycling & Spin Classes

Padded cycling shorts are ideal for long spin sessions. Pair with a supportive sports bra and a breathable top. Avoid loose clothing that could get caught in the bike.

What NOT to Wear to the Gym

Just as important as knowing what to wear is knowing what to avoid:

• Cotton — Cotton absorbs sweat and stays wet, making you feel heavy and uncomfortable. Stick to performance fabrics.
• Jeans or denim — Restrictive and uncomfortable. Never appropriate for the gym.
• Jewellery — Rings, necklaces and bracelets can be dangerous during exercise. Leave them at home.
• See-through leggings — Always check your leggings are squat-proof before wearing them to the gym.
• Worn-out trainers — Old shoes with no support can cause injury. Replace them regularly.

Building Your Gym Wardrobe on a Budget

You don’t need to buy everything at once. Start with the essentials and build from there:

• 2–3 pairs of quality leggings
• 3–4 sports bras matched to your activity level
• 3–4 gym tops (mix of crop tops and tanks)
• 1–2 pairs of gym shorts
• 1 pair of quality trainers
