2025 Arnold Classic heavyweight bronze medalist Chinedu Andrew Obiekea (Andrew Jacked) garnered attention for his hulking physique. Four-time Mr. Olympia Jay Cutler believes Jacked has the physique that could match the legacy of eight-time Mr. Olympia champion Ronnie Coleman.
Jacked earned his IFBB pro card in 2022. He placed fifth at the 2023 and 2024 Mr Olympia contests and is continually in the conversation as a future champion.
Andrew Jacked’s Push Session
- Pec deck flyes
- Smith Machine Incline Bench Press
- Machine Converging Flat Chest Press
- Machine Converging Decline Chest Press
- High-to-Low Cable Pec Flyes
- Cable One-Arm Lateral Raise
- Standing Angled Calf Raise
Time Under Tension & Chest Press Variations
Jacked warms up with pec deck flyes, staying upright with slightly bent elbows for better chest isolation and minimal front delt input. He squeezes peak contraction for two seconds each rep, except for a 10-second hold on the last rep to maximize time under tension (TUT).
Paused eccentrics, or holding the stretched position, might be more hypertrophic. Jacked biased his upper chest and mid-gap line with 30-degree incline presses. (1)(2)
Jacked levels up his chest using the converging chest press, which combines adduction and stability and enables squeezing with heavier loads.
Jacked understands the value of lateral raises for the V-aesthetic. His preferred way to lateral raise is with his thumbs down, which could overactivate the traps without proper mind-muscle connection.

Calves Over Abs: Aesthetic Prioritization
Prioritizing lagging muscles is a data-backed strategy. Calves are commonly a genetic weak point that can detract from an otherwise world-class physique. Targeted calf training can potentially remedy that imbalance.
I’m not too concerned about abs. It’s naturally there; I need calves more.
—Andrew Jacked
In 2024 and 2025 studies, performing calf raises in only the stretched half of reps led to better growth than full reps and shortened partials. Likewise, standing calf raises could double calf gains compared to seated ones. Push sets close to failure to optimize the stimuli. (3)(4)(5)
