Effective exercise

This is an excerpt from Smarter Workouts 2nd Edition by Pete McCall.

The General Adaptation Syndrome, identified by endocrinologist Hans Selye, describes how the physiology of the body adapts to a physical stimulus such as exercise. When beginning an exercise program, an initial alarm phase of one to three weeks occurs during which the body recognizes that a new stimulus is being applied. This is followed by an adaptation phase of 4 to 16 weeks during which the body adapts to the stimulus and becomes more efficient at tolerating it. Finally, after an extended period, up to 12 to 16 weeks, the body reaches what is called the exhaustion phase during which the stimulus no longer has a significant effect (Haff and Triplett 2016).

Many different methods of exercise are promoted with the promise to help you achieve results, making it challenging to identify which approach is best for you. The goal is to find an exercise program that works without wasting energy on frivolous efforts, so how can you filter through all of the marketing noise to select the right type of exercise for your needs? When creating your own workout program, the key is in identifying and performing the most effective exercise for your particular needs. The first step is to identify the three general modes of exercise, then the discussion will focus on how to apply each mode to a workout program that delivers the desired results; the three modes are: mobility training, strength training, and metabolic conditioning.

The purpose of mobility training is to reduce muscle tightness and increase tissue extensibility, which together enhance the functional range of motion (ROM) of a particular joint. When muscles become overly tight, they can pull two bones closer together, removing space from a joint capsule, potentially restricting the degrees of freedom available for movement; therefore, one easy way to think about mobility training is: creating space in the joints. When there is more space in a joint capsule, the bones have more room to move freely. Mobility exercises also enhance coordination and dynamic balance, while helping prevent injuries caused by repetitive stress or prolonged inactivity.

Strength training enhances the force production and coordination of the muscles that control how your body moves, enabling them to perform greater amounts of physical work. Strength training increases a muscle’s ability to generate force, which not only expends energy (burns calories) but also enhances muscle tonus, the natural state of slight contraction that gives muscles a more defined, aesthetically pleasing appearance. Key benefits of strength training include the following:

• Improved muscular strength and force output
• Elevated resting metabolism (calories burned at rest)
• Enhanced functional performance in daily and recreational activities
• Reduced risk of chronic diseases and age-related conditions

Although aerobic exercise has long been considered essential for cardiovascular health, evidence shows that strength training may provide equal, or greater, health benefits. When it comes to long-term health, building and maintaining muscle through strength training is increasingly seen as essential.

Metabolic conditioning focuses on the cardiorespiratory system to place oxygen in the bloodstream and pump it, along with the macronutrients used to metabolize the adenosine triphosphate (ATP) that fuels all cellular activity, including muscle contractions. Metabolic conditioning improves your body’s ability to deliver oxygen and nutrients to working muscles while clearing metabolic waste, allowing you to sustain physical activity for longer durations. Its benefits include the following:

• Increased overall energy expenditure (helpful for fat loss)
• Improved cardiorespiratory efficiency and circulation
• Enhanced endurance and exercise performance

Metabolic conditioning can be adjusted based on intensity. Lower-intensity interval or steady-state training relies on aerobic pathways, which primarily burn fat for fuel. Higher-intensity interval or steady-state training taps into anaerobic pathways, which depend more on carbohydrates and improve your ability to perform at higher intensities before fatigue sets in.

Strength training and metabolic conditioning are closely connected because they improve a muscle’s ability to generate ATP, the energy source for muscle contraction. Low-intensity, high-repetition resistance training primarily targets type I (aerobic) muscle fibers, which rely on oxygen to produce ATP. Moderate- to high-intensity training recruits type II fibers, which can generate ATP quickly using carbohydrates, with or without oxygen (anaerobically).

Over time, this increases metabolic efficiency, helping muscles become better at producing energy during both aerobic and anaerobic efforts.

To train for health and longevity, it’s helpful to adopt strategies used by athletes: focus on improving movement efficiency through integrated, full-body exercises rather than isolated machine-based movements. Athletes train to perform better at their sport; similarly, you can train to improve your ability to move well and stay active in your favorite hobbies and daily activities.

The human body is designed to move, and one of the most valuable outcomes of consistent training is the ability to move without pain or restriction. When movement feels better, you’re more likely to move more often, and that consistency is the foundation of lasting health.
