Training for the Three Bridges Half Marathon is in full swing with a two hour run undertaken today. For someone who was not fit six months ago this is great progress. It has been most helpful to have lost weight prior to starting the training. By losing weight previously I am not causing extra stress to my joints etc with the raised level of activity.
While my runs are typically between one and two hours I wonder what the minimum level of activity is to keep fit? I wonder where the recommendation of a minimum of half an hour of moderate exercise orginally came from. Has it been actually tested? So many studies are based on this level of activity but why is this standard being used?
So get off the couch and get moving. Any exercise is better than none.
