No, but I did have a workout buddy for the first year or so that I was going, so that probably helped. But anyway, I'd still recommend a trainer as he might be able to identify any weak spots in your posture, mobility etc and give better personalized advice than what you'd find online. Had I had one early on, I might not have ended up as a hunchback with huge arms and chicken legs after my first few years of training (I've luckily been able to develop a more balanced physique since).
