Let’s talk about VO₂ Max!
At X4, our programming is built around 4 core elements — and VO₂ Max is one of them.
Your VO₂ max is your body’s oxygen ceiling — basically, how big your engine is. The higher it is, the easier hard efforts feel.
It’s also one of the strongest predictors of long-term health out there — better than cholesterol, blood pressure, or BMI.
When you train it, your heart gets stronger, your body uses oxygen more efficiently, and you recover faster.
That’s why we make it a priority in every X4 program.
You’re not just getting fitter — you’re building a bigger engine. 🔥
