The hardest session you will ever do is the first one back. Not physically. The physical part is easy, because you will not be doing much. It is walking in knowing you used to be fitter, and feeling like everyone can tell.
I coach a lot of men in their thirties and forties in Paisley who have not trained properly since school or since football stopped. This is what I tell all of them.
Nobody is looking at you
This sounds like reassurance. It is just true. Everybody in a gym is thinking about their own set, their own phone or their own reflection. The idea that a room full of strangers is tracking your bench press is a story your head tells you, and it costs people years of their life.
The one exception: if somebody does notice you are new and struggling, the overwhelming likelihood is they offer to help. That is genuinely what happens.
Go too easy for the first two weeks

Everyone does the opposite. You feel motivated, you go hard, you cannot walk properly for four days and you never go back. That cycle is the single most common reason people fail, and it is entirely avoidable.
Leave two or three reps in the tank on everything for the first fortnight. You are not training for results yet. You are training to still be doing this in March.
Learn five movements, not fifty

You need a push, a pull, a squat, a hinge and a carry. That is it. Five patterns covers almost everything worth doing, and getting good at them will take you further than any amount of machine hopping.
If you do not know what those are, that is fine, and it is about twenty minutes of being shown properly.
Book it like an appointment
The sessions that happen are the ones in the calendar. The sessions that do not are the ones you were going to fit in.
Expect the first month to feel like nothing
Six weeks in, you will not look different. You will feel different first: you sleep better, the stairs stop being a thing, and you notice you are less snappy by Thursday. Those are the signs it is working, and most people ignore them because they are waiting for the mirror.
The mirror is slower. It comes, but it is not the early signal.
If you would rather not do it alone
Being shown what to do by somebody who has done it a thousand times removes most of the first-month problem. That is the entire point of personal training in Paisley: not motivation, just not having to guess.
And if the thing that put you off is carrying an injury or a back that has never been right, get that looked at before you start rather than after. It is worth the fortnight it costs you.
