Jason Momoa’s Fitness Philosophy
At 6’4″ and somewhere north of 230 lbs, Jason Momoa has one of the most recognizable frames in Hollywood — and he built almost none of it the way you’d expect. He’s said repeatedly that he hates the gym. Bodybuilding bores him. What he actually loves is rock climbing, surfing, skateboarding, and swinging weapons around on a film set.
That’s the whole philosophy in a sentence: train for the thing, not for the mirror. Momoa has been climbing since he was a teenager and still treats bouldering as his primary conditioning work. The barbell stuff only gets dialed up when a role demands it — and right now, with Legendary’s live-action Street Fighter locked in for an October 2026 release and Momoa cast as Blanka, the barbell stuff is very much in play.
Training Split
When Momoa prepped for Aquaman, he worked with trainer Eric Laciste on a high-volume, body-part-split program built around supersets, pyramid sets, and short rest. The emphasis was on pumping blood into the muscle rather than grinding out heavy singles — Momoa’s joints have taken a beating from years of climbing and stunt work, so max-effort powerlifting isn’t really on the menu.
Here’s the structure that approach follows. Rest is kept to 45–60 seconds between sets, 90 seconds between supersets.
Day 1: Chest and Triceps
- Incline Dumbbell Press – 4 sets x 10-12 reps
- Flat Barbell Bench Press – 4 sets x 8-10 reps (pyramiding up in weight)
- Weighted Dips – 3 sets x 10-12 reps
- Cable Flyes (high to low) – 3 sets x 15 reps
- Rope Pushdowns superset with Overhead Rope Extensions – 3 rounds x 15 reps each
- Push-ups to failure – 2 sets
Day 2: Back and Biceps
- Pull-ups (wide grip) – 5 sets x max reps
- Bent-Over Barbell Rows – 4 sets x 10 reps
- Single-Arm Dumbbell Rows – 3 sets x 12 reps per side
- Lat Pulldowns – 3 sets x 12-15 reps
- Barbell Curls superset with Hammer Curls – 4 rounds x 12 reps each
- Dead Hangs – 3 x 45 seconds
Day 3: Legs
- Back Squats – 5 sets x 8-10 reps
- Romanian Deadlifts – 4 sets x 10 reps
- Walking Lunges – 3 sets x 20 steps
- Leg Press – 3 sets x 15 reps
- Standing Calf Raises – 4 sets x 20 reps
Day 4: Shoulders and Arms
- Standing Overhead Press – 4 sets x 8-10 reps
- Dumbbell Lateral Raises – 4 sets x 15 reps
- Rear Delt Flyes – 3 sets x 15 reps
- Shrugs – 3 sets x 15 reps
- Arm superset (curls + pushdowns) – 4 rounds x 12 reps
Day 5: Climbing and Core
- Bouldering session – 60-90 minutes
- Hanging Leg Raises – 4 sets x 15 reps
- Weighted Planks – 3 x 60 seconds
- Battle Ropes – 5 rounds x 30 seconds on, 30 off
Cardio Routine
Momoa doesn’t do treadmills. His cardio is almost entirely play-based — climbing, surfing, mountain biking, and paddling. A hard bouldering session already spikes his heart rate for an hour-plus, which covers most of the conditioning he needs.
On film prep, stunt rehearsals fill the gap. Fight choreography, weapons drills, and wire work run two to four hours a day and hit the same energy systems as interval training. When he does need traditional cardio to lean out, it’s short — 20 to 30 minutes of stair climbing or rowing, three or four times a week.
Role-Specific Training
Aquaman and the DC Films
For Justice League and Aquaman, Momoa spent four to five months with Laciste building size, then held it through long shoots. He added noticeable back and shoulder width — the trident work and underwater rig time demanded serious shoulder endurance.
Chief of War
His Apple TV+ series Chief of War, which premiered in August 2025, leaned hard into Hawaiian warfare training — leiomano and spear handling, haka, canoe paddling. That’s rotational, grip-heavy, conditioning-driven work, not hypertrophy work, and it kept him lean and mobile rather than bulky.
Street Fighter
Momoa hasn’t broken down his Blanka prep in detail yet, and anyone claiming exact numbers is guessing. What’s clear from the character is the brief: Blanka is a raw, animalistic brawler built on explosive lunges and grappling. Expect the emphasis to sit on posterior chain power, grip strength, and fight-camp conditioning rather than a bodybuilding pump. Principal photography ran through 2025 for the October 2026 release, meaning the physical prep started well before cameras rolled.
Recovery and Flexibility
Momoa’s recovery is low-tech. He’s a sauna guy, a stretching guy, and a big believer in simply being outside. He’s talked about climbing as a form of moving meditation — it forces mobility through the hips and shoulders that most lifters never train.
Deep tissue massage and physio are regular fixtures during shoots, given the volume of stunt work. He also keeps his kids and his motorcycles in the schedule, which sounds like a lifestyle note but functions as active recovery. Sleep gets protected hard during prep blocks.
Personal Trainer
Eric Laciste is the name attached to Momoa’s biggest transformations, including the DC films. Laciste’s approach with Momoa emphasized volume over max load — lots of supersets, controlled tempo, minimal rest — to build size without wrecking a body that’s already carrying a lot of mileage. On location, Momoa often trains solo or with the stunt team, using whatever’s available: kettlebells, ropes, bands, bodyweight.
