Frequently asked questions

What's in the cardio accessories category?

Which accessories actually improve training results?

Two categories give the biggest real-world training benefit: heart rate monitors (let you train in the right intensity zones instead of guessing) and good hydration (high-quality water bottles that you'll actually carry). Smartwatches and fitness trackers help with consistency through tracking. Everything else is convenience or preference.

Do I need all this to train effectively?

No — consistent training is what drives results, and nearly any accessory is a "nice to have" rather than a requirement. That said, a simple heart rate monitor under $80 provides real training data that steering by feel alone can't match. Everything else (bags, water bottles, upgrades) is about comfort and consistency.
