When I signed up for my first Hyrox race—a fitness competition combining eight-kilometer running with nine obstacle stations—I knew I needed a watch that could track everything from split times to obstacle-specific metrics. That's why I opted for Amazfit, and I was quite pleased with the results. 

For context, Amazfit is a more affordable brand that's growing increasingly popular, even becoming the “Official Wearable Technology Partner and Timekeeper” of Hyrox events. But even if you have no plans to put yourself through Hyrox training, the brand offers a versatile lineup of fitness watches, and I’m seeing some great deals on them during Prime Day. 

• The Active Max is on sale for $132.99, down from $169.99. This is a great budget option with a large 1.5″ ultra-bright AMOLED display.

• The Active 3 is on sale for $137.26, down from $169.99. Compared to the Active Max, it has a smaller display, but its lighter weight is targeted specifically at runners.

• The T-Rex 3 is on sale for $226.09, down from $277.99. While Amazfit is gaining popularity primarily for its budget options, the higher-end "rugged" models are starting to earn their keep, too. This watch is built for durability in extreme conditions, so if you've got an adventurous summer ahead, the T-Rex line is worth considering.

• The Balance 2 is on sale for $218.49, down from $299.99. This is a solid mid-tier option, offering features like dual-band GPS and offline maps at a competitive price.

While my Garmin still has my heart when I'm marathon training, Amazfit edges it out when it comes to the best Hyrox training experience. It turns out you don't always need to spend $300+ to get the best training metrics (and during Prime Day, you're getting even better value).
