Physical activity is one of the most important aspects of your life, especially considering the lousy diets that we are adopting nowadays. However, as you are aging, your body may not be able to run the same amount of exercises as it used to when you were younger.
So you could be spending less time on the exercise bike, doing chest exercises, or shoulder exercises. However, what you need to understand is that being 40 doesn’t necessarily mean being weak or having no stamina for exercises.
It is recommended that when you try to run some breathing exercise, lower back exercises, aerobic exercises, or any other types of exercises to talk to a specialist. The latter is the one most qualified to guide you for the right exercising schedule considering you age, whether you are in shape or not, and other factors.
