Are You Stressing Your Muscle Gains Away

Train, eat, and sleep. That's how most think the muscle building process goes. At surface level it's not a bad summary, but obviously there is much more to it.

An overlooked element of building muscle is the things that take away from it. Too often we try to get the newest supplement or recovery tool to support hypertrophy. But when was the last time you shifted your mindset onto what you should stop doing?

I'm not talking about drugs or alcohol, those are obvious. I'm talking about stress.

Stress is something we all know we need to manage better. But since it's a part of life we tend to brush it off and accept it. However, research suggests that being chronically stressed can limit your ability to gain muscle.

Researchers call it the energy constraint model. Your body runs on a fixed energy budget. Every biological process (fighting infection, repairing cells, thinking, moving) must share that budget. When one process demands more, others get less.

There is a hierarchy of importance when it comes to your energy demands. Vital costs take top priority. These are things like your heartbeat, breathing, and brain function. Obviously, without these you would die, which is why it takes top billing.

Second priority are your stress demands. These include responding to threats and demands like exercise, infection, psychological stress, and inflammation.

The last priority is what researchers call growth, maintenance, and repair, which they abbreviate as GMR. For the context of this article, these are the gains in muscle we want, separate from the stress demands of exercise itself in the previous section. When something else demands more of your energy, GMR is the first category to get cut.

Chronic stress is expensive. Psychological stress, obesity, chronic infection, and inflammation all drain energy from the GMR bucket. Not only does this mean less hypertrophy, but also accelerated aging and disease.

Sleep, exercise, and relaxation work by freeing up GMR. Sleep shifts energy away from stress systems and toward repair. Exercise seems counterintuitive (it's a stressor), but the recovery period after exercise is when GMR expands and beneficial adaptations occur. However, this is under the assumption you are not overtraining.

Social interaction is energetically efficient. Being around safe, familiar people reduces stress costs, freeing energy for repair and longevity. This potentially explains why social isolation shortens lifespan.

The research suggests that muscle building doesn't just occur in the gym. Managing chronic stress isn't some woo-woo, feel-good suggestion. It's a biological necessity for getting the most out of your training. The gains you're chasing might not be limited by what you're adding to your routine, but by what you're failing to remove from your life.
