A routine designed for athletes who are limited by their muscles' ability to utilize oxygen. This training focuses on short, high-intensity intervals to improve oxygen utilization at the muscular level.

• Enhance muscular endurance
• Improve oxygen utilization in muscles
• Increase power output in short bursts

Perform a 20-minute all-out test to determine your:

• Threshold power
• Watts per kilogram

This test helps identify if you're more likely to be delivery-limited or utilization-limited.

• Determine your threshold power
• Calculate your watts per kilogram
• Gain insights into your physiological limitations

Interval training is an excellent way to improve overall conditioning in a short period. There are many types of interval training, each with a different training effect. This video explains how to detect what is limiting your conditioning (the heart and/or the muscle) and how to train according to your limitation.

Perform the 515 test to identify if you are limited by oxygen delivery or utilization. This test involves progressively increasing intensity with rest periods, allowing for analysis of muscle oxygenation patterns.

• Identify your physiological limitations
• Gain insights into your muscle oxygenation patterns
• Determine the most effective type of interval training for you
