Well, I like running everyday outside.
Inside I like to stretch, do pushups, situps, lift weights, etc. in front of a TV. I also have an exercise machine that doesn't make much noise for relaxing at night.
I just have a routine I follow everyday xP If it makes me sweat and feel tired, its good!
Well. Usually needs a young priest and an old priest. Some holy water, a cross and a bible.
Then you shout 'THE POWER OF CHRIST COMPELS YOU!' Several times.
