Most training tools measure how hard you work. The Helio Strap Pro measures how well.
Built for hybrid athletes who need more than heart rate, it captures movement quality, muscle load, and cardio effort together, giving you a more complete picture of how your body performs under real training stress.
See More Than Heart Rate
Heart rate tells you how hard. Movement tells you how well. As fatigue builds across strength and endurance work, how the body moves often changes before athletes realize it. The Helio Strap Pro helps reveal those shifts earlier so you can maintain control and train with greater precision over time.
One System. A Complete View of Performance.
A multi-sensor setup across the wrist, arm, and waist creates a broader view of performance that a single wrist sensor cannot. When paired with Balance 3 or Balance Ultra, Hybrid Training Dynamics brings movement quality, muscle load, and cardio effort together into one connected view of efficiency, fatigue, and execution.
Built Around Official HYROX Training
The Helio Strap Pro integrates directly into official HYROX Race and Simulation Modes. Train every station with greater structure and precision. As fatigue compounds across disciplines, the system helps reveal how the body responds, supporting more consistent execution over time.
Intelligence That Works After You Do
The Zepp App brings it all together after each session, connecting workouts, recovery, nutrition, and daily habits into one continuous view of progress. No required subscription.
Built to Go Where Your Watch Cannot
The Helio Strap Pro extends tracking beyond the wrist when your smartwatch is charging, resting, or not being worn. Designed for flexibility across training, recovery, and sleep, it works alongside your routine whether paired with an Amazfit smartwatch or worn independently.
Train With Precision.
Track every second and recover every day with a connected system that brings strength, endurance, and recovery together. No subscription required — just precision.
