To start exercising, you do not need to be 20 years old, this is a myth. Anyone can do some physical activity from the age of 40, 50, or even 60 years.
However, depending on your age, the amount of exercise you can do is reduced, especially if you have never done any physical activity in your life. It is for this reason that you should have some basic considerations, especially if you want to start running.
Dose the exercise
The most common mistake made by beginners is trying to do everything at the same time. If you have never run, you cannot go out every day and run several miles. This will only exhaust you, and you will stop exercising quickly.
You need to learn to dose your training sessions. If you're just starting, run two or three days a week with rest days in between. Over time, you will be able to run more often, but you should never stop resting, your body will thank you for it.
If you have trouble running, walk!
At first, it will be difficult to maintain a fast pace when running. If this is the case for you, then you can follow a routine where you run and walk following a specific cycle.
For example, you can follow a 1:2 ratio between running and walking. This means that you will walk twice as long as you will run. After two or three months your body will be more adapted to exercise, so you can modify this ratio to 1:1 (run the same time you walk).
Finally, with 5 or 6 months of training, you will be able to run longer, and you will not need to walk. It's all a matter of discipline and dedication.
Don't forget the weight training
Finally, you cannot forget to perform strength exercises. This type of training is essential to ensure the proper functioning of your muscles and, believe it or not, it helps you burn body fat. Strength training will not only help you get faster, but it will also help prevent running injuries.
