Transition to Bodybuilding
Although his strength numbers were massive, John wasn’t fully satisfied with how his body looked.
He felt his chest still looked small and “deflated,” despite lifting over 700 lbs. That frustration sparked a shift.
In college, he changed his training style: he moved from heavy, low-rep sets (3–5 reps) to hypertrophy-style training (8–12 reps), focusing on volume and muscle development rather than pure strength.
At the same time, he tracked macronutrients and calories precisely learning to feed his muscles, not just fuel his strength.
Over time, his physique “exploded” into impressive shape retaining strength while building size, symmetry, and definition. He still benched heavy, but now looked proportional and aesthetic.
Bodybuilding Competitions & Pro Card
John’s first formal bodybuilding competition was in 2012, at the NPC Lackland Bodybuilding show in the Middleweight division.
He won first place, which fueled his ambition to compete further. Over the next few years, he competed in several NPC shows placing in top spots in events like the Branch Warren Classic (2014) and the NPC USA (2015).
In 2016, John took a big step forward: he competed in the NPC USA Championships as a Heavyweight and earned his IFBB Pro Card by winning first place.
That same year, he made his professional debut at the IFBB Europa Phoenix Pro, finishing 5th in his class. That debut confirmed his ability to compete among the best in the pro ranks.
Training & Nutrition Philosophy
John emphasizes that transforming physique is a science and an art. He believes that genetics play a role some body parts, like his chest, simply lagged behind others. The solution was smart programming:
- He teaches focusing on exercise selection (e.g. wide grip bench to target chest),
- Tailoring rep ranges to goals (strength vs. size),
- Adjusting nutrition as goals shift bulk vs. cut, muscle vs. definition.
He often demonstrates how he used budget-friendly ingredients in his early years like oats ground in a coffee grinder, inexpensive whey protein, olive oil, and even sweet potato baby food for calories.
The point: you don’t need fancy tools just consistency and resourcefulness.
He also stresses the importance of squats, especially front squats for quad development or back squats for overall leg strength.
Hack squats can serve as a useful alternative but he prefers barbell work when possible.
He describes competition prep as relentless: “Prep never starts or stops—it’s just a nonstop continuation to the ultimate goal.”
