What are the base intensity parameters for the bike and strider?

The base intensity parameters for the bike and strider are defined to ensure participants engage in an effective cardiovascular workout while maintaining a challenging yet sustainable effort level. The range of 60-100 RPM is designed to match the expected physical capabilities of participants during the base pace segment of the workout. This RPM range promotes steady aerobic conditioning, which is essential for building endurance.

In addition, the specification of Gear 6+ provides a guideline for resistance, ensuring that participants are working hard enough to elevate their heart rates into the ideal zone for enhancing fitness levels without overexerting. This combination of RPM and gear encourages proper form, muscular engagement, and energy expenditure, optimizing the effectiveness of the workout.

In contrast, the other options suggest ranges or gear levels that would either be too low or too high for the base intensity, potentially leading to inadequate aerobic conditioning or excessive fatigue. Hence, the parameters outlined in the correct answer strike a balance that is both challenging and achievable for participants.
