MEET BOB.
He joined a gym. Things went badly.
Bob is the nervous but well-meaning heart of Muscle Mayhem. He joins Iron Temple Fitness determined to make a change - then discovers confusing machines, protein shakes, sore muscles, gym etiquette and awkward moments he definitely wasn’t prepared for.
It’s funny, painfully relatable and ultimately a story about confidence, belonging and having the courage to show up again.
THIS IS NOT A FITNESS GUIDE.
It’s a gym comedy about starting, failing, laughing and showing up anyway.
Muscle Mayhem follows Bob through the awkward, confusing and completely unpredictable world of gym life - from questionable workouts and protein-shake disasters to friendship, confidence and learning not to take yourself too seriously.
Funny. Relatable. Heartfelt.
MEET THE AUTHOR.
DIMITRIS JAMES IORDANIDIS
Melbourne-based author Dimitris James Iordanidis created Muscle Mayhem from a simple idea: the gym can be intimidating, ridiculous and genuinely funny - especially when you’re the new person trying to work out what everyone else seems to already know.
Behind the laughs is something more human: confidence, self-belief, friendship and the courage to keep showing up when you don’t feel like you belong.
Muscle Mayhem is his way of turning those awkward moments into something people can laugh at, relate to and hopefully see a little of themselves in.
