Who Is JK Simmons?

A post shared by Jonathan Kimble Simmons (@j.k.simmons.official)

Jonathan Kimble Simmons is a professional actor in Hollywood and is considered one of the most established actors of his generation. He was born in Grosse Pointe, Michigan, attended Ferry Elementary School in Grosse Pointe Woods, and when he was 10, his family moved to Ohio.

He attended Worthington High School, where he was active in drama, music, and football. When he turned 18, he moved to Montana and graduated with a Bachelor of Arts degree in music. Simmons spent some time honing his skills in the theater until he landed his first role on Broadway in 1992. During his time on Broadway, he played Captain Hook in Peter Pan.

Later, JK Simmons made his first TV appearance, playing a patrol officer in Popeye Doyle. He also played several iconic roles on the silver screen, including the three Sam Raimi Spider-Man films, Jennifer’s Body, Whiplash, Kong: Skull Island, Justice League, The Tomorrow War, and many more.

While his work in Whiplash won him the award for Best Supporting Actor, one of his latest works with Dwayne Johnson, “The Rock,” is what had heads turning due to his physique. He played the role of a jacked Santa Claus in the Christmas holiday movie Red One. 

JK Simmons’ Workout Routine

Interestingly, the secret to JK Simmons’ ripped physique is listening to his trainer. His training concept is called cumulative blood volume training. This is where he does high-volume training that focuses on the number of sets and reps for each muscle group. This helps increase muscle hypertrophy as you pump as much blood as possible.

His cumulative blood volume training is designed to be executed for at least one to two months. He groups his training into two categories: cardio and functional training. Simmons stated that when he doesn’t make time to work out, he doesn’t feel as fit or as good as he would want. His workouts are intense, with many compound and isolated exercises at a high-volume. Let’s take a look at his exercises below.

Workout 1

JK Simmons starts his exercises with warmups, which involve performing dynamic stretches and using an elliptical bike for ten minutes at 140 bpm. This study shows that doing warm-ups before your major exercises can help improve your exercise performance (1).

After his warm-ups, he performs nine different exercises of four sets each, averaging 10-12 reps. He supersets these exercises with 45 seconds of rest between each exercise. However, when doing his superset exercises, he does them back to back without resting. His first workout routine works his chest, shoulders, back, and core muscles.

Exercises Sets Reps 
Superset — Flat Dumbbell Press & Reverse Grip Dumbbell Press410-12 
Superset — Machine Chest Press & Cable Crossover410-12
Superset — Wide Grip Lat Pulldown & Hammer Grip Pulldown410-12
Machine Hammer Strength Row410-12
Superman 4 10-12
Crunch412-15
Hanging Leg Raise320
Machine Ab Crunch 312-15
Lying Oblique Crunch15 Reps for Each Side

Workout 2

He uses the same principles of workout one, incorporating warm-ups and supersets with little rest in between. This workout routine targets his arms, shoulders, and core muscles. 

Exercises Sets Reps 
Standing Dumbbell Curl & Arm Blaster412-15 (Last Set is AMRAP)
Superset — Standing Cable Curl & One-Arm High Cable Curl315

Hammer Curl Using Dumbbells315

Plank Push up430 Seconds 
Forearm Plank430 Seconds 
Plank Jack430 Seconds 
Side Plank with a Twist 430 Seconds 

Workout Notes

JK Simmons spends between 50-120 minutes during workouts, depending on whether he’s training for a role. His general goal is staying healthy and enjoying the muscles that come along with that. Below are key things to take away from his training approach. 

Consistency

JK Simmons has been training consistently for over 15 years. He says he finds energy and vitality in the gym often. At 70, the actor is reaping the benefits of this consistency as he remains active and youthful for his age.

High-Volume Training 

JK Simmons trains at high volume. He and his trainer focus on the number of sets and reps for multiple muscle groups. The goal is to pump as much blood as possible into the muscles, which is good for hypertrophy. A study shows that a higher training volume can help with greater muscle gains (2).

Compound and Isolated Upper Body Exercises

JK Simmons does a mix of isolated and compound movements, mainly targeting his upper body. Before starting his major routines, he always does warm-ups, which help with his mobility and movements for his major exercises. His warm-ups include stretches and ten minutes on the elliptical bike.

Supersets and Dropsets

When training, Simmons incorporates multiple methods for maximum strength and muscle growth. He incorporates supersets and drop sets and occasionally trains to failure using as many reps as possible (AMRAP). Research shows that supersets can increase efficiency and reduce training time (3).
