The problem with that statement is that it's basically a tautology, since the words "balanced", "healthy" etc. hide all the complexities. What is a "balanced" diet? What is moderately fit? What is the definition of a healthy social life?
> What is a "balanced" diet?
Eating all the necessary macro and micro nutrients in bounds of callorie requirements.
> What is moderately fit?
Walk for 5km without issue. Do 10 pushups. Do 20 situps. Do 20 squats.
> What is the definition of a healthy social life?
Dont let work be your whole life. To many people free time pretty much boils down to having dinner and going to bed. Instead engage more in socializing outdoors.
Squats are often considered one of the most challenging exercises, as my physiotherapist points out. It's easy to underestimate them – I did 70 squats once and ended up straining my back.
The key to a proper squat is maintaining stable back support throughout the entire movement. This principle isn't just crucial for squats; it's fundamental for all heavy weightlifting exercises. It's also incredibly relevant to everyday tasks like doing laundry or cleaning, as these activities often involve similar lifting motions.
This concept is known as maintaining stability in the sagittal plane. However, it's equally important to focus on coronal and axial support, strength, and pain-free movement.
It's worth noting that exercises like situps and pushups, often seen as simpler, can also be performed incorrectly by beginners.
Regarding diet, it's an even more complex topic. Nutrition needs can vary greatly from person to person, and a one-size-fits-all approach is rarely effective. It's essential to consider individual differences and specific circumstances when discussing dietary advice.
The others aren't and are person dependent.
Does it? There are some things that are obvious to anyone paying attention. We can tease out details ad nauseum but what is the point in that if you can get 95% of the way there just by being sensible.
What's sensible? How many workouts per week? What kind? What food to eat? How much of each?
Good health doesn't have to be an exact science. Forgoing processed foods, forgoing too many calories, and taking a daily walk is sufficient for the average person. The questions you are asking here only matter at the extremes (professional athletes, et. al.), not to the average person.
But have it your way in the mire of pedantry you've carved out for yourself.
