Be cautious with interventions aimed at accelerating recovery. Methods like ice baths and NSAIDs can actually compromise long-term muscle adaptation. They work by reducing inflammation, but that short-term inflammatory signal is a crucial part of the muscle-building process.

The body actively resists change and maintains its current state (homeostasis). To stimulate muscle growth, you must apply a stress greater than what it has previously adapted to, forcing it to reinforce itself. This requires a "bloody good reason" to change.
For injury recovery, the initial focus should be on clearing congestion and improving lymphatic drainage. This "clears the highway" for more productive healing and strength work like BFR (Blood Flow Restriction) training to follow, accelerating the overall process.
The body is designed for the immune system to perform maintenance and repair work at night. This prevents it from crippling your energy and focus during the day. This nocturnal activity is why delayed onset muscle soreness is often most pronounced in the morning after a workout.
The act of training creates damage and stress; it doesn't build muscle directly. Growth occurs during the recovery and overcompensation phase. Training again before this process is complete is counterproductive, like constantly demolishing a half-built wall.
The idea that you must consume protein within a narrow window post-exercise is a myth. Research shows that muscle protein synthesis remains elevated for over 24 hours after resistance training, making immediate protein intake unnecessary for optimizing muscle growth.
While light weightlifting builds muscle, lifting heavy (around 80% of one-rep max) is required to produce specific neural effects. This intensity releases myokines—chemicals that cross the blood-brain barrier, reduce inflammation, and stimulate the growth of new neurons in the hippocampus.
Contrary to popular internet wisdom, data shows that cold plunges do not increase cortisol. Instead, they decrease cortisol while boosting adrenaline, dopamine, and norepinephrine, making you alert and focused without the negative stress hormone response.
Cytokines, the molecules of inflammation, are essentially distress signals from cells that are struggling energetically. For example, the cytokine IL-6 released after intense exercise is the muscle's way of signaling it needs energy mobilized from other parts of the body.
Dr. Will Bolsiewicz distinguishes between life-saving acute inflammation (fighting infection, healing injury) and detrimental chronic low-grade inflammation. The latter is a constant, damaging immune response likened to a “forever war” inside the body, which is at the root of many modern diseases.
The temporary increase in hormones like testosterone and growth hormone after a workout is not the primary driver of long-term muscle growth. Structuring workouts specifically to maximize this acute response is ineffective and not predictive of long-term adaptation.
