The principles of exercise are universal. They apply equally to you, me, and everyone else. However, the best application of those principles will vary significantly between us due to differences in genetics and other factors affecting how our bodies respond to exercise.
Many people try one exercise program for a while, switch to another, then another, hoping to eventually find one that works for them. Others just follow whatever program their favorite bodybuilder or athlete or the current champion endorses.
The first group are like someone who goes into a clothing store and randomly tries on different sized clothing.
The second are like someone who insists on buying the exact same clothes the fashion model in the store advertisement is wearing, in the exact same size.
Neither are likely to find something that fits them properly.
If you want your clothes to fit well you should select something based on your size or have it altered to fit you.
The same is true of your workouts and diet.
The numerous workouts on this web site and in my books are meant to be examples or starting points to be tailored to you. They will produce very good results for most if performed as written, but if you want the best possible results from your workouts you must adjust them based on your body’s response to exercise.
