Most beardies slow down with age. Younger ones have a million things to discover. When you see a picture of someone's beardie just 'hanging out', remember that it is just a picture and chances are that they were only able to keep them still for that second.
You can get a baby play pin and let your beardie climb around in that. For outside, you may want to get a bit more inventive and maybe someone else can step in with a better idea for the outside. I don't trust birds not to try to steal my babies, so I just perch them on me and let them soak up the rays.
