Remember to eat well and make sure you get enough protein, otherwise it's hard to follow the program.

Also, you need to be doing them on a lifting platform for the end of the lift, when you have to drop the weight all the way to the floor. Not too many gyms (in the UK, at least) seem to have these.
That being said, I'm sure I have bugs in some of the exercises, I try to work them out via. videos and focusing on technique before I put more weight on the bar.
All the gyms I've been to here in Denmark have lifting platforms, squat racks, etc. so that hasn't been a problem for me.
They have a 'how to post a form check' guide: https://www.reddit.com/r/Fitness/wiki/rules#wiki_2._how_to_p...
When the parent said compound lifts they were referring to lifts that (when you are doing them heavy and correctly) are whole body exercises: Deadlifts, squats, and bench are the three main lifts. Programs will typically mix in some other lifts to round out the program a little like power cleans, overhead press, and bent over rows.
Most beginner strength programs are three days a week, I've found most people do Monday, Wednesday, Friday, but it's flexible as long as you have at least one rest day in between workout days. If you don't mess around and just go to the gym to work you can easily be done in 30-45 mins so under 3 hours a week is very realistic.
You will absolutely feel uncomfortable when you start. Everyone does. Read a lot about form and pay attention to yours (gyms have lots of mirrors, lift near some especially when you're starting out). It's really easy to hurt yourself once the weight increases if you have bad form. Consider getting a good personal trainer to teach you the fundamentals of the lifts.
