During class, coaches do not actively encourage members to reach which heart rate zone?

Coaches do not actively encourage members to reach the Red Zone during class due to the intense nature of this heart rate zone. The Red Zone indicates that a member is working at 91-100% of their max heart rate, which can be difficult to sustain for any significant duration and poses a higher risk for injury and overexertion. While it is important for participants to understand the benefits of pushing into this zone occasionally for improved cardiovascular fitness and to push their limits, it is not a zone that coaches promote as a sustained target during a typical workout.

In contrast, the Green Zone, Blue Zone, and Orange Zone are all encouraged as they support more sustainable levels of effort that facilitate endurance, calorie burn, and effective heart rate training without overwhelming the participants. The focus of Orangetheory Fitness is to create a workout that balances heart rate training while ensuring safety and effectiveness, which is why the Red Zone is approached with caution.
