1. What is Cycling Strength Zone?

The Strength Zone in cycling represents the power output range that is 90-120% of your Functional Threshold Power (FTP). This zone is crucial for improving muscular endurance and sustained power output.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( FTP \) — Functional Threshold Power in watts
• \( 0.9 \) — Lower bound multiplier
• \( 1.2 \) — Upper bound multiplier

Explanation: The calculator multiplies your FTP by 0.9 to get the lower end of your strength zone and by 1.2 to get the upper end.

3. Importance of Strength Zone

Details: Training in this zone helps improve your ability to sustain high power outputs, crucial for time trials, breakaways, and hilly terrain.

4. Using the Calculator

Tips: Enter your current FTP in watts. The value must be greater than 0. For best results, use an FTP value from a recent test.

5. Frequently Asked Questions (FAQ)

Q1: How often should I test my FTP?
A: Most cyclists test every 4-6 weeks to track progress and adjust training zones.

Q2: Is the strength zone the same for everyone?
A: While the percentage range is standard, the actual wattage values will vary based on individual FTP.

Q3: How long can I sustain efforts in this zone?
A: Typically 3-20 minutes, depending on fitness level and exact intensity within the zone.

Q4: Should beginners train in this zone?
A: Beginners should focus on building aerobic base first before incorporating strength zone workouts.

Q5: How does this compare to other cycling zones?
A: This is more intense than tempo zone but less than VO2 max zone. It bridges the gap between sustainable and maximal efforts.
