Do the right exercises if health and longevity is your goal.
Exercising for Longevity
Everyone knows that exercise is good for you and necessary for optimal health. However an excess of most everything can create problems. It's important to realize that strenuous exercise creates free radicals in your body and if you aren't getting proper rest and adequate nutrition you are damaging and prematurely aging your body. Also many supposedly good exercises like running and weight training can be doing your body more harm than good. If you are running multiple miles 5-6 days a week especially on asphalt or concrete, you are most likely damaging your joints and aging faster. If you are working out several times per week and lifting heavy weights overhead, you are most likely compressing your spine and tearing your body down long term. Unless you are in your twenties and training for sporting events I don't recommend doing either one if you want to age well and feel well all of your life.
The following are the exercises I recommend for feeling great and living as long as possible. Most of these exercises incorporate muscle strengthening, aerobic training, flexibility, balance, good posture and what I call Functional Fitness. Functional Fitness is basically using your own body weight as resistance as you exercise. This type of training not only helps you function better in your normal daily activities, it is easier, safer and fun to do. You can do flexibility and aerobic exercises everyday and resistance exercises 2-3 times per week.
