A sports bra is essential - learn how to choose the perfect one!

A good sports bra isn't a luxury, it's a necessity! Regardless of breast size, every active woman needs proper support during training. Here's everything you need to know!

Why is a sports bra so important?

Cooper's ligament protection

Breasts don't have muscles—they're supported by delicate ligaments. When running or jumping, breasts move in three planes! Without support, these ligaments can stretch, leading to sagging breasts.

Comfort

A regular bra isn't made for movement. Underwires, hooks, and seams can pinch and chafe during exercise.

Confidence

When you feel comfortable and safe, you can focus on your workout, not your discomfort.

Types of sports bras

1. Compression

How they work: They press the breasts against the chest
For whom: Small/medium bust (AC)
Best for: Yoga, Pilates, gym, stretching
Advantages: Comfortable, easy to put on
Cons: Insufficient support for larger busts

2. Encapsulation

How they work: Each breast has a separate shirt (like a regular bra)
For: Medium/large bust (C-G+)
Best for: Running, HIIT, intense cardio
Advantages: Maximum support, natural shape
Disadvantages: Often more difficult to put on

3. Hybrid

How they work: A combination of compression and encapsulation
For whom: All sizes
Best for: All-purpose
Advantages: Good support + comfort

Support levels

Low Support (Low Impact)

Activities: Yoga, Pilates, stretching, walking, gym (upper body)
Features: Light, comfortable, minimal support

Medium Impact

Activities: Gym, cycling, dancing, brisk walking
Features: More support, often with built-in cups

High Support (High Impact)

Activities: Running, HIIT, jumping rope, aerobics, team sports
Features: Maximum support, wide straps, strong underbust band

How to choose the right size?

Step 1: Challenge Yourself

Underbust circumference: Measure just below the breasts
Circumference at the widest point: Across the fullest part of the breast

Step 2: Check the size chart

Each brand has its own chart - ALWAYS check before purchasing!

Step 3: Try it on

It's best to try on several sizes and models.

Perfect Match Test

Underbust band:

  • ✓ It should be firm but not constricting
  • ✓ It should not pull itself up
  • ✓ You can put two fingers under the belt
  • ✗ If it leaves deep marks - it is too tight

Cups/Compression:

  • ✓ The breasts are completely covered
  • ✓ No "quadboob" (overflowing from the top)
  • ✓ No gaps or material wrinkles
  • ✗ If your breasts are leaking - it's too small
  • ✗ If the material wrinkles - it is too big

Straps:

  • ✓ They don't slip off
  • ✓ They don't cut into your shoulders
  • ✓ Adjustable is a plus!

Movement test:

  • Jump in place
  • Do some jumping jacks
  • Arm swings
  • Lean forward

If something shifts, presses or rubs - it's not the right model!

What to pay attention to?

Material

Search: Polyester, nylon, elastane - moisture-wicking
Avoid: 100% cotton - absorbs sweat and takes a long time to dry

Seams

Best: Flat, seamless, or seams on the outside
Avoid: Thick seams inside - they can rub

Clasp

Over your head: Simpler, fewer things to break
With clasp: Easier to put on, adjustable

Additional features

  • Built-in cups (removable pads)
  • Phone pocket
  • Reflective elements
  • Adjustable straps

Care

  • Wash after each use (sweat destroys elastic fibers!)
  • Hand wash or machine wash in a washing bag, 30°C
  • No fabric softener
  • Air dry (NOT in the dryer!)
  • Do not iron

When to replace?

Sports bras lose support after approximately 30-40 washes or 6-12 months of regular use. Replace if:

  • The belt stretched
  • The straps are slipping off
  • You feel less supported
  • The material stretched

How many sports bras do you need?

Minimum: 2-3 (one worn, one in the wash, one spare)
Optimal: 4-5 (if you exercise daily)
Perfect: Different models for different activities

Remember: A good sports bra is an investment in your health and comfort. Don't skimp on this piece of your workout wardrobe!
