3 Keys to Building Muscle

Adding muscle to your frame can be hard. There’s no way around it. Building muscle can be a slow and frustrating process and takes months of consistency and hard work to attain results. However, if we understand what stimulates muscle growth, maybe we can optimize the process and reach our goals in less time and with less frustration.

#1: Metabolic Stress

One key to stimulating muscle growth is to induce metabolic stress in the muscle fibers. This is done by overloading the anaerobic energy systems that provide our muscles with energy during resistance training. Increased metabolites from high anaerobic stress elicits a potent anabolic hormone response which stimulates muscle growth.

High Metabolic Stress Can Result From…

High repetitions: 8 – 15+ reps
Moderate loads: 65 – 85% of 1 rep max
Short rest periods: 30 – 90 seconds

#2: Mechanical Stress

Another key to building muscle is to induce mechanical stress in the muscle fibers. This is done by overloading the structural proteins of the muscle itself. Disruption of the structural components of the muscle fibers is primarily caused by lifting heavy and elicits a potent response leading to muscle growth.

High Mechanical Stress Can Result From…

Low repetitions: 1 – 6+ reps
Moderate to Heavy loads: 75 – 95% of 1 rep max
Longer rest periods: 2+ minutes

Another benefit to lifting heavy is that it recruits the highest amount of muscle fibers. When a heavy load is lifted, it takes a great amount of force which must be supplied by recruiting more and more muscle fibers within the muscle. Lifting with lighter weights won’t stimulate all of the available muscle fibers and thus not all muscle fibers will be stimulated to grow. Muscle fibers must be activated to promote significant muscle growth.


Pro Tip:
By slowing down the lowering phase of an exercise (AKA the negative or eccentric phase), one can actually cause greater mechanical stress, potentially resulting in a greater muscle-building response.

#3: Periodization

As you may have noticed, the two prior keys to building muscle are a bit different from each other. The first requires high repetitions with lighter loads, while the second requires heavy loads and fewer repetitions. So which do I choose? Well, if you’re new to training, the first method is going to be much safer and allow you to practice form before adding a bunch of weight. However, to see increases in both strength and size it’s important to include both types of training. This can be done by periodizing your training program. Essentially, you’ll spend periods of time focusing on different phases. Periodization allows you to experience adaptations from both styles of training – optimizing your potential for muscle growth. Also, don’t forget to practice post-workout muscle recovery techniques!
