The Myth to Debunk: There's No ONE Ideal Sports Bra
Many women wear the same sports bra for all their activities. This is a mistake. The support needed depends directly on the intensity of the impact: yoga, fitness, and running engage the chest very differently. Choosing the right sports bra is essential for long-term breast health.
The 3 Levels of Support
Light Support
For low-impact activities: yoga, pilates, stretching, lounge, relaxation.
Characteristics: bralette style, soft elastic band under the bust, soft fabric, not necessarily with cups.
What you feel: discreet support, complete freedom, zero compression.
Medium Support
For moderate-impact activities: fitness, weight training, dance, tennis, moderate cardio.
Characteristics: wide elastic band at the base, firmer straps, compressive fabric, sometimes reinforced under the bust.
What you feel: firm but comfortable support, you forget you're wearing it during exercise.
Firm Support
For high-impact activities: running, trail running, HIIT, CrossFit, boxing, horse riding.
Characteristics: crossed or racerback straps, very wide elastic band, significant compression, often reinforced cups.
What you feel: true containment, ideal for repeated high-intensity movements.
How to Find Your Size
At Onamaste, the standard sizing chart is as follows:
- S/M: bust circumference 85-90 cm, cup sizes A/B/C
- L/XL: bust circumference 95-100 cm, cup sizes C/D/E
The measurement to take: rib cage circumference (under the bust) as close as possible, without excessively tightening.
Signs That a Sports Bra Isn't Right For You
- ❌ The elastic band under your bust rides up when you move → too big
- ❌ The band leaves deep marks after 30 minutes → too small
- ❌ The straps fall down → wrong fit or size
- ❌ You feel bouncing during exercise → insufficient support for the activity
- ❌ The fabric doesn't dry after sweating → material unsuitable for sports
Recommended Materials
- Polyester + Spandex (80/20): the perfect balance for intensive sport
- Nylon + Elastane: softer, ideal for yoga and pilates
- Cotton + Elastane: only for lounge and very gentle yoga
Care: 3 Golden Rules
- Machine wash at 30 °C, in a laundry bag
- Never tumble dry
- Alternate between several sports bras to extend their lifespan
