Sure, it is easy to simply put on some trainers and head out for a run. But training in this manner will only bring small benefits in the short term, and you will quickly lose motivation in the long term.
Before you start training, you need to consider the following aspects.
Why are you running? What is your purpose for running? What is your goal? You might want to lose weight, improve your cardiovascular, or run faster. Whatever your goal is will greatly impact your approach to running.
How much time are you willing to dedicate to your goal? There is no right answer here. Everyone has different amounts of time available. However, it is worth considering before you start so that you don’t set unachievable goals or easy goals that you reach without trying.
