Exercise, which is intellectually stimulating aswell! And free!

 This is a very effective exercise routine, which I do when it’s very cold outside . It costs nothing.

Make sure you wear non slip shoes.

Make sure there are no hazards on the floor.

Put on some wrist weights and/or ankle weights - I use 1lb weights for my wrists.

Put your phone timer on for 30 minutes

Select something interesting or useful to watch on your phone. Or put classical music on.

Hold your phone horizontally, chest height, and firmly with both hands.

Turn the programme on and the timer, and start walking around your house, while moving the phone backwards and forwards.

If you have chosen something interesting to watch or listen to - the time will fly by.

You will be giving your hear and arms a good workout, and also your legs.
