Before you join in for the first time, ask the person who looks after you if it's safe for you to do the exercises. Do you have space to join in? Have you picked everything up off the floor? Are you wearing clothes you can move in and trainers?
Now you are ready to get fit and enjoy exercising with Joggy Bear. You can watch the exercises, learn how to do them and then join in with him. See if you can copy them.
