Personal trainer turned me off and now I lack motivation!!!

First of all, congrats on your loss and it's wonderful you want to lift. Honestly, there's not THAT much he could have done for you in one session. He probably could have been more helpful, but usually you don't learn how to lift in one introduction training session.

You should start by reading and reviewing beginners strength programs: Starting Strength, New Rules of Lifting for Women, Strong Curves, Strong Lifts 5x5. All of these programs explain the lifts, show pictures/videos. Give a look at the websites for Starting Strength and Strong Lifts and go from there. Continue asking questions here.

Ugh! Those type of trainers suck. I don't have a problem with them trying to sign you up because at the end of the day that's how they make a living but pushy sales techniques and not helping you because you aren't going to sign up is not okay. They shouldn't call it a free session if there's a catch. The good news is that he probably was a crappy trainer anyway. Good ones are generally pretty busy and sought after so wouldn't need to resort to that.

The key is just to start somewhere. Google a beginner program and just pick something and stick to it. As a beginner you'll see pretty good results with just about any program done consistently so don't let perfect get in the way of good. Look for something that's full body, 2-3 times a week, utilises mainly free weights and cables and includes mainly compound movements (working lots of muscles at the same time like squats, deadlifts, pull-ups, bench press, rows, over head press).

Here are some tips that might help you get over that initial fear:

- Once you find a program, spend a bit of time on you tube watching instructional videos and practicing the basic body weight movements at home.
- Make a plan and stick to it. Put head phones in and execute plan. Pretend you know what you're doing.
- Utilise progressions - starting with a basic versions of an exercise and building up (body weight squat, goblet squat, back squat). Again google is your friend
- Start lighter and add weight slowly once you get comfortable with the movement (not too slowly though, a lot of females underestimate what they're capable of)
- Most exercises can be modified to be done with dumbells. You might be more comfortable starting with dumbells so you can pick them up and find your own space. Eventually as you lift heavier weights and get more comfortable in the gym you can move to barbells
- Bring a friend and workout together.
- Be couretous, return your weights when finished, wipe down your benches, ask if people are finished etc.

Most importatntly, remember that you have as much right as any of those guys to be in any part of the gym

Meh... Lots of crappy trainers. Lots of good ones too. Also plenty people who will teach you for free. Just start asking. Get on YouTube and find a routine and follow it. Check out Christine Salus workouts on YouTube. Awesome!

Realistically, he could not have taught you how to lift in an hour. Not possible. I am guessing he was seeing this as an introductory session, where he would get to see what you can do, what you are interested in, and then start building a routine for you. One single session with a trainer, I can only see it working out if you were already following a plan and had a couple of very specific issues you need help with. I can see "I need you to work with me for one hour to help correct my squat form" being reasonable, but "I have never done this before, show me how to lift in one session", it does not sound doable.
If you feel lost even after doing some research, are there classes at your gym? If there are classes including weights, then maybe attending a few would help you get some more confidence and understand the basics. Otherwise, choose light weights, start working on form in front of a mirror and be patient.

I wouldn't let some stranger ruin my motivation if I were you. I never worked with a trainer. I just got some lifting books from the library (New Rules of Lifting, Starting Strength) and just started (my husband did eventually help me, but I had to start on my own). Most people at the gym are going to pay very little attention to what you are doing...unless it is something VERY unsafe or VERY awesome.

If you are really uncomfortable lifting around others, just try going at off-hours. My gym is least crowded around 9-11am...and then in the evenings after 6pm; and very early...around 4am.
