One of the ways I am increasing my daily activity is by using a concept called natural movement exercises. You can research the internet on the topic, but basically put, the process involves repeated sets of transitional actions like getting up from laying on the floor, standing up from a chair, and the like.
You might think these would be easy exercises and wonder what the point is, but if you’re at all out of shape, you’re likely to discover they’re not easy at all and are going to be the first step toward fixing the problem.
I have started a routine wherein I do about five minutes of these exercises every hour (I use a timer on my phone to keep me honest). My goto exercises are getting up from a laying position on the floor, crouching and standing, and walking up and down my stairs. The number of repetitions I do varies depending on my stamina at the time.
I can already tell the difference in the fact I am doing them in two particular ways: first, I am more mentally alert that I would otherwise be, and second, my back does not hurt as much as it normally does.
Granted, these kinds of exercises are not a replacement for dedicated exercise like walking, but throughout the course of the day, they help teach my body to be more active and, therefore, to use energy better. In the long run, especially as I am more able to do other kinds of exercise, these activities will help promote overall health.
