The 34-year-old was in action north of the border at the Glasgow International on Saturday, beginning his season with victory over 60m.
Chambers crossed the line in 6.58 seconds – the second-fastest time in the world this year – to beat former world champion Kim Collins and American Mike Rodgers.
He will now turn his attentions to March's European Indoor Championships in Sweden and he admits he feels better than ever – especially now that he has a coach barking orders at him.
"It feels good to be able to openly acknowledge I have a coach to work with," said Chambers, who has teamed up with Loughborough-based American Rana Reider.
"It just helps going into the season to not have any stress. It allows me to sleep at night and focus properly. I do now finally feel part of the team, so that's nice.
"I've grown in age but not in body. I've still got the mental drive and approach that I had when I was 22, 23. It's almost like I'm Benjamin Button - I'm going backwards.
"I still enjoy what I do. I just want to see how fast I can run before the tyres fall off."
