Lifestyle: Leading a lifestyle that spells good health is a combination of different factors that includes exercise and eating right. About a decade ago, for me, good health meant either being able to perform a certain exercise like bench press, running, etc. If you really want to assess your health, then you need to look at your overall health, which would mean mental, emotional and physical health.
Be active daily for mental health
Prolonged periods of inactivity are often the cause of anger, frustration, lethargy and depression. On the other hand, those who are active regularly experience a better mood, feel more energetic, and overall enjoy a better life.
Be active daily for physical health
Being active does not necessarily mean doing a 25km run daily, and nor does it necessarily mean squatting double your bodyweight daily. Even lighter activities like walking, swimming, yoga, playing with kids, cleaning up the house, riding a bicycle, etc are all examples of being active. For most people, intense activities like weight training, sprinting, etc should ideally be kept to about 3-5 times a week, and on the other days, lighter activity is recommended.
Strength train and lift heavy
Almost every month there seems to some study that comes out with the finding that strength training, including lifting heavy weights has multiple health benefits. Starting from weight management, increased energy levels, better glucose metabolism, etc there are many reasons why you must strength train. You can strength train by using your own bodyweight and lifting barbells, dumbbell, kettlebell, etc.
Now cardio does not necessarily mean doing painfully long and slow activities like distance jogging. It can also be done in a short time with intense activities like sprinting, circuit training, kickboxing, etc. Infact, the intense options seem to provide better results overall, in terms of cardio fitness, improving body composition, increasing growth hormone production, etc.
Maintain healthy bodyweight and bodyfat levels
The extra fat increases your chances of getting a heart attack, diabetes, hypertension, etc. Also, I would like to mention that extra bodyweight, even in the form of muscle is not necessarily healthy in the long run. Whether muscle or fat, the extra weight has to be carried around by your joints, and at a later age, that can really start telling on your joint health.
Check your BMI
A good way to calculate your ideal bodyweight is to use the BMI calculator. Now I know that a lot of people feel that the BMI is not an accurate way to measure ideal bodyweight, but in my opinion, unless someone has unnaturally huge muscles thanks to steroids, the BMI is a reasonably accurate calculator of one's ideal bodyweight.
Maintain ideal flexibility and mobility levels
Most people in their 20's have already lost a lot of flexibility that they had when they were 5 years old. So you can only imagine how much tighter they will get when they are in their 40's and 50's. The good news is that it doesn’t have to be this way. You can improve your joint mobility and flexibility levels as long as you work on it. You should be able to touch your toes.
