The 7-week protocol that turned this time-poor founder into Super Dad.
With some clients the universe has a special way of connecting you.
It was a cold winter morning on the eve of the second 2021 lockdown and the Sydney CBD was a ghost town.
A disaster for my business and also for Justin’s first restaurant (he now has 16).
I’d been getting breakfast most mornings for about a month at his shop when we finally went beyond the usual pleasantries.
I began to learn Justin was currently suffering from some lacklustre results in the gym accompanied resulting in crippling back pain.
16 hour days on his feet, a young family and 5 hours sleep a night was par for the course for the 41 year old.
Over the next 3 years we built Justin from what he would call “skinny fat” with constant back issues to now a built, lean and pain free “super dad”.
After a long strength and muscle building phase, where he reached a life time goal of being 80kg he decided to do a fat loss phase and got some rapid results.
Here’s how he did it:
1. The Training Program
a. The weekly routine
Monday | Upper Body |
Tuesday | Lower Body |
Wednesday | Rest |
Thursday | Upper Body |
Friday | Lower Body |
Saturday (optional) | Light activity (high step count) |
Sunday | Rest |
b. Upper / lower body day example sessions

2. The Diet - Rapid Fat Loss
a. How we structured it
Overview: Justin is around food all day which can create temptation in his routine. He also operates off less sleep than we’d like which can make dieting challenging as you’re more hungry when tired.
After spending the last 3 years with us being told to eat, eat, eat to gain muscle it was a big change to now have to restrict himself
Justin normally trains at 5:30am
b. Typical daily structure
“Biggest piece of advice from me is discipline. I kept it up on weekends too — if you’re going to do the shred, then commit to it or don’t do it at all. May as well try for the best results you can!”
3. The Lifestyle Shifts
“I think the other thing to note, is that I’m 44 and had never dieted before in my entire life! So this was a real challenge to be conscious of what I’m eating.”
4. The Results
Week 1 → Week 7
“It’s not just physical — it’s a mindset shift that makes every tough day worth it.”
