What Happens When You Cross Your Aerobic Threshold?

What happens when you push beyond your aerobic threshold?

In this video, TRACER co-founder Joey Wilson breaks down what changes inside your body as intensity increases, lactate production rises, and your aerobic system can no longer meet the full demands of your effort.

We explore what lactate actually is, why it begins to accumulate at higher intensities, and what your body’s response can tell you about your fitness and training. Understanding where these changes happen — and how your body responds to them — is a key part of training smarter, improving endurance, and getting faster.
