Why does one training program work great for some, but not for others?
Because each athlete is unique.
This doesn't mean that you are always an exception to the rules, but everyone responds differently to training depending on age, genetics, sex, current fitness level, etc. And these differences can drastically affect your response to a given training routine.
You can’t just follow some cookie-cutter program endorsed by your favorite celebrity. What works for them probably won't work as well for you. (They most likely have help from plastic surgery and Botox anyway.)
With our modern understanding of human physiology, a one-size-fits-all approach just won't cut it anymore. We don’t believe in making vague promises to the masses when we know that each person’s mileage will vary.
In order to get the best results, you have to look at the evidence, take into account individual variation, and apply the science of exercise and adaptation within the context of your unique situation.
And that's exactly why we built Fytt.
Using data from the most reliable science and coaching sources, it builds out fitness programs customized for each individual. As you train and record your results on Fytt, the software learns and adapts in order optimize the routine for your body and your circumstances.
So stop blindly following advice from random people on the internet. You are a unique athlete. Follow a program that takes into account your current fitness level, your ability to recover, and other factors that affect your response to athletic training.
Join Fytt, and start training intelligently.
