HIIT Intervals - Stick to Them!

Hi everyone,

I’d like to share the recent outcomes of my FTP tests. I underwent laboratory testing, where we conducted a lactate threshold test, MOXY analysis, and VO2 max assessment.

The results were incredible because they confirmed one key thing – following the prescribed training on Athletica has worked wonders for me!

Here is part of the outcome from my test:

"One of the most surprising and positive findings was your very strong VO2max, which is likely a result of high-volume comfortable long runs (which enhance mitochondrial density) combined with high-intensity interval training (HIIT), which stimulates mitochondrial function, myocardial contractility, and lung capacity under exertion. The physiological intersection of these adaptations has resulted in a very well-developed metabolic profile, which promises strong performances in upcoming races and training goals.

In training, I would continue with your well-structured approach, which effectively builds aerobic endurance (through endurance and VO2max sessions) while also improving movement economy—especially high-quality long runs done in a controlled manner within Zone 1/Zone 2."

As highlighted in the results, HIIT intervals and over-under sessions played a crucial role in these improvements. I know they hurt, but trust the process and stick with them!

If anyone has questions or wants to share their experiences, feel free to reach out!
