Strength training gives meaning and purpose to every gym session for me personally. Look into Stronglifts 5x5 - it's 3 exercises a session and all you really need is a squat rack, so if you go to a proper gym they should always have one open. With proper form, nutrition and patience, you could go from squatting the bar to squatting 2 plates in a couple months. I've done some form of this on/off for around 7 years.
