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.

Daily grip strength is a reliable proxy for systemic nervous system recovery. A drop of 10% or more from your baseline indicates you are not fully recovered and should likely skip training that day to prevent overtraining and injury.

Avoid static stretching immediately before a workout or competition. It alters the muscle's length-tension relationship, forcing your brain to recalibrate stored motor patterns (engrams). This recalibration period temporarily impairs coordination and performance in skilled movements.

The body restricts movement into ranges where it is weak to protect itself from injury. By actively training for strength at the full extent of your motion (e.g., full-depth squats), you signal to your nervous system that the range is safe, which in turn increases your functional flexibility.

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.
