1. Lowest price on the market
2. Customer Service post-purchase was fantastic. They kept me updated on the order status and even coordinated installation with their G&G partner in the area
3. Installation was quick - and free!
4. I’ve only used it a handful of times this far, but the Spirit treadmill is such a noticeable upgrade over my previous ~$800 machine. Really smooth and sturdy.

Great value for a quality treadmill delivered very quickly exactly when promised and in perfect condition; only minor quibble with assembly instructions which could have been a bit easier to understand. We highly recommend doing business with Gronk Fitness!

Treadmill arrived right on time! Set up was easy with just two people and some simple instruction. A few interval sessions and a long run so far. Running great 👍
