To build a visible six-pack can often require blood, sweat and tears.
He recommends buying the necessities first, like a food scale and tracking app.
The trainer claims keeping track of food is just as important for anyone who is serious about building their abs.
Paul said: “I’m not suggesting you weigh out everything for the rest of your life, but just understand what you’re getting.
“We tend to repeat meals, and once you have a pattern of eating, you can start tracking.”
In addition to tracking your food intake, Paul also spoke about the fitness aspect of things.
He added: “My favourite exercises for really developing is decline sit-ups.
“And I don’t do a lot of them I’m not doing hundreds of reps… Between 10 and 20 reps and I’ll do multiple sets of that.
“Then I’ll do hanging leg raises, and then I’ll usually do some kind of planking or something to work on my core stability.”
Then in order to drop fat and achieve definition, Paul recommends fitness fans to introduce a calorie deficit to their diets.
He concluded: “I would suggest low-intensity steady-state.
“It’s going to break down fat for fuel, whereas something like sprinting, HIIT intervals, your body is going to use glycogen for fuel.”
