It is important to do something you like when it comes to fitness. If cycling gets your motivation level up and keeps you consistent then go for it! If it’s running that does the trick for you then hit the bricks. Resistance training is also a great way to get exercise and stay fit. Out of these three modalities which one do you think includes most of the major fitness components, which one is most comprehensive?  Now, before you answer let me explain the criteria of which to base your answer on. The major fitness components are as follows:
Strength
Aerobic fitness
Flexibility
Muscle Endurance
Body composition
core stability/strength

    We will leave out nutrition and mental well being because they do not apply. Which one of the modes of exercises mentioned above covers more of the fitness components than the other two? Which mode will be effective in keeping:
 body fat levels healthy,
 aerobic fitness at a high level
 sufficient flexibility to reduce risk of injury
 adequate strength levels in major muscle groups
muscle endurance
core stability/strength

    If you’ve answered resistance training you answered correctly. Strength training enhances bone mineral density along with muscles, tendons and ligaments reducing the occurrence of osteoporosis. Recent studies show competitive cyclist have suffered from bone mineral deficiencies such as osteopenia. Osteopenia is a precursor to osteoporosis. Click here to read more about this research. Cyclists had the worst bone mineral density compared to runners and resistance trained exercisers. Runners scored highest on the bone mineral density scale. Weight lifters had the highest body weight. Body fat percentage was similar in all populations.  The study does not test for flexibility, muscle endurance or core strength and stability. I am here to state that resistance training protocols can be manipulated to improve all of these components. Flexibility is improved during strength training exercises that are completed through a full range of motion. Running and cycling tend to decrease flexibility in certain joints of the body and do not use full ranges at the respective joints involved. Both running and cycling are performed in the same ranges and planes of motion repetitively. whereas strength training movements can be performed in many different ranges and planes of motion. Decreasing the risk of overusing certain muscle patterns.Â
 
    Strength training protocols can be designed to improve muscle endurance, muscle strength, aerobic fitness and by design as mentioned above, flexibility. A lighter weight, higher repetition with short recovery periods will improve muscle endurance, body composition and flexibility. Let’s not forget about it’s traditional purpose of increasing muscle strength with heavy loads and sets of ten repetitions or less. An even lighter load, higher repetition range and sets that last 60 seconds or more can improve aerobic fitness. Neither cycling or running can be as ” flexible” (no pun intended) as resistance training when it comes to manipulating results. Lastly, there is very little core strength and stability involved in cycling comparatively speaking. Running requires a certain level of core stability to maintain an upright, efficient biomechanical position. But the core activation is restricted to the sagittal plane. Resistance training can be performed in all planes of motion yielding by far the most core conditioning response of the three modes of exercise.
    The moral of this blog is to make sure you pay attention to other components of fitness. exercising solely on the bike can put you at risk for bone density issues. Not including resistance training if you are a runner can leave you susceptible to flexibility issues and overuse injury. Optimal fitness is achieved by taking a big picture approach. Don’t have tunnel vision. Equal parts of all of the aforementioned fitness components are essential to a happy, healthy life. Refer to a personal trainer in the Boston area like myself for further assistance.
