Cardio Accessories: How to Choose

As My Fitness Outlet, we curate cardio accessories that actually upgrade your workouts—whether you’re protecting floors, tracking heart rate, or turning a climber into a full-body station. Because accessories span wearables, straps, mats, and add-ons, the key is matching the tool to your use case. We’re an authorized dealer for 50+ premium brands, we price-match identical in-stock items, and most in-stock accessories ship fast with free delivery and U.S-based support if you need help before or after you buy.

Focus on decisive specs: Compatibility/Connectivity (e.g., ANT+/BLE with Garmin devices or STEPR anchor points), Battery/Power (coin-cell vs. rechargeable and real-world runtime), Water/Material durability (ATM rating for wearables or rubber/PVC thickness on mats), and Footprint/Size (so it fits your space or body). Pick a heart-rate strap if you want the most accurate zones, a GPS smartwatch for all-in training metrics and mapping, protective mats to reduce noise and wear, and upgrade kits to add strength, mobility, and tracking to your cardio routine.

Cardio Accessories FAQs

Which cardio accessories work with my existing treadmill, bike, or rower?

Protective mats are universal; heart-rate straps and watches connect to compatible devices via ANT+ and/or Bluetooth. Check each product’s compatibility to ensure it pairs with your console, app, or watch.

Do Garmin chest straps work with non-Garmin equipment?

Yes—if your equipment, app, or bike computer supports ANT+ and/or Bluetooth heart-rate profiles. Pairing is typically done from the equipment/app settings.

How water-resistant are the smartwatches?

Water ratings vary by model (for example, some are 5 ATM and others 10 ATM). Always check the product page for the exact rating before swimming or showering.

Do I really need a mat under my cardio machine?

A quality mat reduces vibration and noise, protects floors, and helps stabilize equipment—especially useful for upstairs rooms or shared spaces.

What are typical lead times?

Most in-stock wearables and accessories ship in about 1–3 business days; certain upgrade kits may ship in about 3–5 business days. The latest estimate is shown on each product page at checkout.
