There is nothing like a Stormtrooper to help you stay focused
Whether you are doing cardio or lifting weights, getting fit requires you to push your limits. This can sometimes be hard to do if you do not have a goal in mind. However, if motivation is what you lack, perhaps you can enlist a friend to help.
You can also enlist the aid of a Stormtrooper. Why not? They are probably used to discipline, so they will surely be a lot of help when it comes to making you stick to a routine.
