\# Bowflex Treadmill Heart Rate Chest Strap MX338

The Bowflex Treadmill Heart Rate Chest Strap MX338 is a preowned heart rate monitoring accessory for a Bowflex treadmill.

This strap may suit customers replacing a missing or worn component, keeping a Bowflex fitness machine in service, or looking for a used fitness part at a lower cost.

## Product Details and Benefits

This item is identified as the Bowflex treadmill heart rate chest strap, model MX338. Its part number is \*\*1000512189\*\*, and its SKU is \*\*MX338\*\*. The product is supplied as a preowned fitness component and has been carefully inspected by skilled technicians for performance and safety before sale.

A chest strap provides a hands-free way to wear a heart rate monitoring accessory during treadmill workouts.

When the treadmill and heart rate system support the strap, the equipment can use the wearer's heart rate during exercise.

Choosing a preowned part can also reduce waste by extending the useful life of existing equipment and keeping usable components out of landfills.
