Lesson Overview

2.34 – Why Cardio Can Stall Strength (And When It Helps): Cardio can help or hurt strength depending on how it is used. Excessive cardio can compete with strength training by draining recovery resources. Long endurance sessions can change muscle signaling and reduce power output. This is known as the interference effect. However, light cardio can improve recovery by increasing blood flow and reducing stiffness. Walking, cycling, or light conditioning can support joint health and work capacity. Timing also matters because cardio done right before heavy lifting can reduce strength output. When cardio is planned intelligently, it supports health without blocking muscle growth. Strength-focused lifters should treat cardio as a tool, not a punishment. The goal is to stay fit without stealing energy from muscle-building sessions. This lesson teaches balance instead of extremes. When cardio and strength work together, performance improves instead of competing.
