Eli Jah is a lifelong fitness enthusiast who believes exercise greatly contributes to character development and happiness. In addition, fitness should serve a purpose beyond enhancing general health or building physical appeal; fitness should be functional. Whether preparing for sporting competitions, physically taxing careers such as military or labor-intensive jobs, or simply a strong desire to see how far you can push your body, Eli Jah can help guide you with practical experience and continuing education.
“Let’s face it, life doesn’t give you handles or a bench and training solely with these types of handicaps prepares you to be gym-strong, not reality-strong.”
What is Full Spectrum Fitness?
The Full Spectrum experience is a broad mixture of elements from CrossFit, strength training, martial arts conditioning and advanced military fitness doctrine. By combining what works from proven approaches while slimming down unnecessary bloat programming, we are left with real, usable athleticism and fitness.

Full Spectrum Fitness: Primary Components
- Cardiorespiratory FitnessCardiorespiratory fitness refers to the ability of the circulatory and respiratory systems to supply oxygen to skeletal muscles during sustained physical activity. Regular exercise makes these systems more efficient by enlarging the heart muscle, enabling more blood to be pumped with each stroke, and increasing the number of small arteries in trained skeletal muscles, which supply more blood to working muscles. Exercise improves the respiratory system by increasing the amount of oxygen that is inhaled and distributed to body tissue.
There are many benefits of cardiorespiratory fitness. It can reduce the risk of heart disease, lung cancer, type 2 diabetes, stroke, and other diseases. Cardiorespiratory fitness helps improve lung and heart condition, and increases feelings of well-being.
The American College of Sports Medicine recommends aerobic exercise 3-5 times per week for 20–60 minutes per session, at an intensity that maintains the heart rate between 65-90% of the maximum heart rate.
- Muscular Strengththe amount of force that your muscles can exert against resistance
- Muscular Endurancethe ability of a muscle or group of muscles to sustain repeated contractions against a resistance for an extended period of time
- Flexibilityor limberness refers to the absolute range of movement in a joint or series of joints, and length in muscles that cross the joints. Flexibility is variable between individuals, particularly in terms of differences in muscle length of multi-joint muscles. Flexibility in some joints can be increased to a certain degree by exercise, with stretching a common exercise component to maintain or improve flexibility
- Balancean ability to maintain the line of gravity (vertical line from centre of gravity) of a body within the base of support with minimal postural sway. Sway is the horizontal movement of the centre of gravity even when a person is standing still. A certain amount of sway is essential and inevitable due to small perturbations within the body (e.g., breathing, shifting body weight for one foot to the other or from forefoot to rearfoot) or from external sources (e.g., air currents, floor vibration). An increase in sway is not necessarily an indicator of poorer balance so much as it is an indicator of decreased neuromuscular control
- Body Compositionis used to describe the percentages of fat, bone and muscle in human bodies. Because muscular tissue takes up less space in our body than fat tissue, our body composition, as well as our weight, determines leanness. Two people of equal height and body weight may look completely different from each other because they have a different body composition
If you Google it you’ll find Full Spectrum Fitness appears to be the name of several clubs and facilities all over. However, here it’s a training philosophy that is at the core of everything I do. The benefits of functional reality training, or what I term Full Spectrum Fitness, is that it’s usable in real life and transferable outside of the gym.
Real movement, real challenges, real fitness
Working to make the body strong in all aspects of kinetic health is the primary focus of RealFit and the basis of Full Spectrum Fitness. The body is not trained to simply be strong for one gym hour out of a day. It should be trained to be strong in all aspects of fitness and that strength should translate to real world efficiency.
