Exercise is a stress on the body and the body adapts to these stresses in a way to 'manage' the stress better the next time. However, the body adapts to the specific stress it encounters. This is the Specificity principle of exercise training. Run and the capillary density of the quadriceps will increase. Press a heavy kettlebell and the neuromuscular recruitment patterns of the deltoid muscle will improve. Perform low-intensity cardio and your metabolism will increase for the duration of the session, but afterwards your metabolism returns to baseline. Take the same amount of time and perform 10 sets of 10 burpees and your metabolism will remain elevated for hours/ days afterward. Specificity.
Not all exercise is equal, but everyone lumps it altogether. A week doesn't pass without the media reporting the benefits of exercise. Your doctor may ask if you are exercising. A friend may tell you that she lost weight because she started a diet and exercise program. Everyone assumes that all exercise has the similar effect on the body. That is the furthest thing from the truth. Not all exercise is created equal. While all purposeful muscular activity performed to enhance health or performance can be classified as exercise, the stress of different types of training applied to the body varies tremendously. Luckily, scientific research continues to figure out how different types of exercise affects diiferent parts of our bodies.
So, I will end this post with some questions.
What is the best type of training to enhance fat loss?
Increase bone density?
Minimize golf injuries?
Run a 5K faster?
Raise your metabolism?
Build whole body strength?
If you answered walking or using the elliptical trainer you would be wrong.
