My dad has been having a lot of chest pain lately. He went to the doctor, and got tested for a few things. The tests were all negative (the good kind), and the doctor told him that the pain must be muscular, i.e. from sitting in a chair too long, from inactivity, etc.
I want to buy some weights, like the ones below, that he can use to strengthen his chest muscles. For example, by doing some dumbbell presses, etc.
Can anyone recommend some workouts that would be good for him to do?
