How to start running
Start small.
Before you start running every day, you should establish a base level of fitness. Running is great for you, but it is physically punishing, and it can wreak havoc upon your body if you aren't ready.
If you start running with no prior exercise habits, you risk hurting yourself before you get into the swing of a routine. Consider starting with daily walks and progressing gradually into running.
