I tried to get into working out a few times in my life, but it was always short-lived, usually because I'd injure myself because I didn't know what I was doing.

Getting a good trainer makes all the difference in the world, and I don't mean a high-school kid at a large commercial gym. My trainer owns his own gym. It has been a real treat to have someone stand there the whole time while working out (1 hour 4x per week) and cheer me on, watch my form, give me advice/tips before starting each set, etc. It's not cheap - mine is $60/hr in the Midwest - but so worth it.
