Amazfit Helio Strap owner - How many band you have?

Hi everyone,

I'm an active user who primarily focuses on Weightlifting and Brazilian Jiu-Jitsu (BJJ), and I'm planning to buy the Amazfit Helio Strap. I'm looking for advice on the best band to wear with it, especially for comfort and practicality.

I've heard the Whoop 4.0 Bicep Band might be compatible with the Helio device. And, I'm planning to buy the Amazfit Helio Armband for comfort.

I have two main questions for the community:

1. BJJ-Specific Comfort & Security

• Has anyone worn a Bicep Band (like the Whoop or a similar style) while training BJJ?
• How does it hold up during sparring/rolls? Does it move a lot, or does it stay securely in place without needing an extra sleeve or retention band? I'm worried about it interfering with grips or being uncomfortable.

2. General Band Management & Hygiene

• How many bands do you typically own and rotate?
• Since I'll be sweating a lot from morning workouts, I imagine I'll need a fresh, dry band to wear when I head to the office afterward. What's your strategy for band rotation and cleaning? Do you swap bands every workout?

Any comments, suggestions, or real-life examples of your band rotation setup would be extremely helpful!

Thank you all in advance!
