How can you prepare yourself for a grueling race like HYROX? According to fitness athlete @erichinman, you need to structure your training to replicate the intense cardio demands of the race. This is how you can be ready at the HYROX starting line: Prepare for the Challenges: A 30-60 minute workout made up of four-minute intervals that include exercises like running, wall-balls, burpees, and biking. Prepare for the Effort: During your intervals, target a heart rate that sits squarely in Zone 4, which is where your heart rate will be sustained throughout the HYROX event. Prepare for the Grind: Layer in Zone 2 cardio, consisting of exercises like running and biking, to provide your body with the durability it needs to prevent it from breaking down late in the race. This strategy can help you conquer one of the most demanding races in the world.
