Building a physique like Alan Ritchson’s Jack Reacher character isn’t just about lifting heavy and eating more.

According to performance coach and former IFBB Pro bodybuilder Nicholas Trigili, the 43-year-old actor likely added 25-30 pounds of muscle to achieve his on-screen transformation.

But here’s what most men over 40 get wrong: they think the answer is simply bulking up or trying to “recomp” from wherever they’re starting.

In a recent breakdown, Trigili revealed the exact three-phase protocol he uses with clients in their 40s and 50s to build Hollywood-level physiques—and why getting lean first is actually the smartest move you can make.

Why Most Men Over 40 Start in the Wrong Place

Ritchson stands 6’3″ and carries 230-240 pounds at a reasonably lean body composition. For most men watching his performance, the instinct is to immediately start bulking.

That approach backfires spectacularly, according to Trigili.

Build Strength and Conditioning With One Simple Tool
FULL-BODY TRAINING

If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.

  • Full-body training with one weight using swings, squats, and presses
  • Solid cast iron build that feels stable and lasts for years
  • Comfortable grip that makes high-rep workouts easier to handle

You’re either losing fat or you’re building muscle. Recomping only works for two type of guys here. A true beginner whose body is brand new to training or someone coming back from a very long layoff who still has the muscle memory to tap into.

The performance coach explains that building muscle on a frame carrying 20% body fat means poor insulin sensitivity and hormonal dysfunction. Food consumed in a surplus gets shuttled primarily to fat storage, not muscle tissue.

Higher body fat also means elevated estrogen, lower testosterone, and systemic inflammation—all working against muscle growth.

Phase One: Get Lean First (8-12 Weeks)

Trigili’s first phase focuses entirely on dropping body fat to around 10-12%. This isn’t about aesthetics—it’s about optimization.

Getting lean improves nutrient partitioning, meaning calories consumed later will preferentially build muscle rather than accumulate as fat. Lower body fat also reveals actual muscle distribution and weak points, allowing for targeted development in subsequent phases.

The Phase One Protocol

Testosterone base: If already on TRT (testosterone replacement therapy), maintain current dosing at 75-200mg weekly. Those considering TRT should wait until several weeks into their cut before introduction.

GLP-1 agonists: Low-dose tirzepatide, retatrutide, or semaglutide help regulate appetite during extended caloric deficits while improving insulin sensitivity, lipid profiles, and reducing inflammation.

Peptides for recovery: BPC-157, TB-500, and KPV address joint pain, gut health, and inflammation—critical foundations for the muscle-building phase ahead.

You cannot build 10, 15, 20, 30 pounds of muscle in phase two on top of joint problems, gut problems. If you’re already compromised, throw it out the window.

Training during this phase should include 4-5 sessions weekly of high-intensity resistance work, with 10,000 daily steps and elimination of processed foods and alcohol.

Phase Two: Strategic Muscle Building (6-9 Months)

Once body fat reaches 10-12%, comprehensive blood work becomes mandatory before transitioning to growth phase.

Essential Blood Markers to Monitor

  • Metabolic markers: Fasting insulin, A1C
  • Lipid panel: Total cholesterol, LDL, HDL, triglycerides
  • Organ function: Liver enzymes (ALT, AST), kidney function
  • Blood health: Hematocrit, hemoglobin
  • Hormones: Testosterone, estradiol, SHBG, LH, FSH

With clean baseline labs established, the building protocol begins.

The Building Phase Protocol

Testosterone titration: Slowly increase from TRT doses, but Trigili warns against exceeding 400mg weekly for physique-focused goals.

If you’re not stepping on a bodybuilding stage, what the hell are you guys doing? You want to build a physique that’s going to be lean, that looks good on camera, that holds up for life.

Higher doses create excessive aromatization to estrogen, requiring additional medications to manage side effects—and producing diminishing returns on actual muscle growth.

Human growth hormone: With optimized insulin sensitivity from phase one, HGH enhances recovery, muscle building, and connective tissue repair.

Secondary compounds: Trigili recommends either Primobolan or Deca-Durabolin, depending on individual response and goals.

  • Primobolan: DHT derivative producing dry, dense muscle with minimal water retention and clean tolerability
  • Deca: Exceptional for joint relief and muscle growth, but carries risk of prolactin-related mental side effects and sexual dysfunction

The performance coach emphasizes that duration matters more than dosage. Moderate compounds run for extended periods consistently outperform aggressive short cycles.

Nutrition and Training Adjustments

Calories increase by just 200-400 above maintenance, targeting 0.25-0.5 pounds gained weekly. Protein stays at 1g per pound of lean body mass, while carbohydrates increase to fuel training volume.

Training shifts to progressive overload across 4-5 weekly sessions with increased volume. Full range of motion and proper technique become non-negotiable—injury at this age can derail progress for months.

Sleep requirements are firm: 7-9 hours nightly. Daily steps remain at 8,000-10,000 to maintain insulin sensitivity, supplemented by zone 2 cardio 3-5 times weekly.

Knowing When to Stop Building

The building phase continues as long as steady progress occurs within healthy parameters. Warning signs to transition include:

  • Weight gain stalling for 6+ weeks despite dialed-in variables
  • Blood work trending negative
  • Disappearing ab definition, jawline, or neck visibility

For most men, this phase runs 6-9 months depending on genetics and adherence.

Phase Three: Peak Conditioning (10-12 Weeks)

The final phase reveals the physique built during months of strategic growth.

Conditioning, you’re not going to get shredded. You’re not going to get chiseled from adding a compound. Conditioning is only about calorie deficits and your diet and your body fat levels.

Testosterone doses decrease slightly to reduce aromatization while maintaining muscle. Anavar or Masteron—both DHT derivatives that don’t convert to estrogen—provide fullness and strength during caloric restriction without water retention.

Caloric deficit increases to 500 below maintenance, targeting 0.5-1% body weight loss weekly. Protein increases while carbs and fats remain moderate, with strategic refeeds implemented weekly or bi-weekly based on leanness progression.

Energy expenditure climbs to 12,000-14,000 daily steps. GLP-1 medications may be reintroduced if appetite regulation or metabolic markers require support.

The Reality Check on Timelines and Expectations

Trigili estimates 12-16 months minimum for a complete transformation to Ritchson-level conditioning—potentially longer depending on starting point and genetics.

This stands in stark contrast to aggressive protocols popularized on social media, which produce temporary size followed by rapid deflation post-cycle and potential health complications.

The coach’s philosophy centers on minimum effective dose and sustainable long-term results over dramatic short-term gains that can’t be maintained.

As somebody who started running steroids aggressively at 15 years old and blasted them for almost two decades as a pro bodybuilder, I know what works and doesn’t work and what’s going to kill you.

For men over 40, the stakes include not just aesthetics but cardiovascular health, hormonal function, and quality of life. Ritchson’s physique represents months of strategic phases, not weeks of aggressive supplementation.

The approach requires patience, consistent monitoring through blood work every 12 weeks, daily blood pressure tracking, and willingness to adjust protocols based on individual response rather than arbitrary timelines.

Most critically, none of these protocols should be attempted without medical supervision from licensed professionals experienced in performance enhancement and hormone optimization.

Building a Hollywood-caliber physique after 40 is entirely achievable—but only through strategic phasing, moderate dosing, comprehensive health monitoring, and the discipline to prioritize longevity over shortcuts.
