Is sweating and burning during workouts what makes muscles grow?
Potential Mechanisms for a Role of Metabolic Stress in Hypertrophic Adaptations to Resistance Training

Surprising Findings
Acute hormonal spikes (testosterone, GH) after training don’t lead to more muscle growth.
Bodybuilders have spent decades chasing post-workout hormone surges with supplements and training protocols—this says it’s all noise.
Practical Takeaways
Focus on progressive overload with heavy weights (70%+ 1RM) for 6–12 reps—skip the endless burn-focused sets.

Your muscles grow bigger mainly because of how much total force they feel over time—not whether you do your workouts all at once or spread out over the week.

When your muscles swell up from the burn during a workout, that puffiness might trick your cells into thinking they’re being stretched, turning on growth signals — like a fake workout signal.
The tiny harmful molecules made when your muscles burn during exercise might actually help them grow by sending growth signals — but too many can hurt instead.
When your muscles get tired and burn during exercise, they release signaling chemicals (like IL-6) that might help repair and grow muscle by activating nearby stem cells — but we’re still figuring out if this really happens in people.
