There are four critical elements to advancing beyond basic, beginner fitness levels.
The 1st is how to sleep, rest, and recover.
Most miss this, and it causes problems for their training and progress.
Your sleep involves your Circadian rhythm, which needs consistency to function correctly.
That means the exact times each day for rising and setting.
One late night isn't going to ruin things, but consistency is critical.
The 2nd is your nutrition.
What you eat, you become.
This includes micronutrients vital to all of life, including making progress in your training.
But many diets are deficient in various vitamins, minerals, and micronutrients.
The best way to get these is through a very colorful diet of whole foods and tailoring the nutrition to your unique needs.
The 3rd is building a foundation of strength AND flexibility.
Many workout protocols skip essential portions of both.
And the training doesn't scale up as the person makes progress.
It's necessary to scale up strength and flexibility, which can be done in a few ways.
One way is steady-state, which is your current baseline of training for 8-16 weeks. Until it gets boring. Then you know your body has adapted. And then you can safely and efficiently scale up because both your body and brain are ready for it if not craving it.
The 4th is developing a plan of attack.
Many miss this, too, because they think in very vague terms.
And this keeps them from attaining things they'd like to achieve.
This is where another problem manifests too.
Trial and error.
On the other hand, when you set the goal in clear rather than vague terms, and you know the step-by-step process you need to get there, it makes it not only achievable but less overwhelming and possible in your mind.
I hope this helps!
