JK Simmon Workout Routine

In 1997, JK Simmons realized he was fairly out-of-shape figure while playing the character Vern in Oz.

Still, the decision to get back to his physical fitness took more than a decade, and a major driving force was Simmons’ sudden increase in weight, almost 250 pounds in 2009.

After the divorce, Simmons decided to take his fitness seriously and to get back on track.

At the time, Simmons was training with personal trainer Dana Perry to improve his fitness level and muscle mass.

However, his recent physique and vascular build is a result of intense training under the guidance of Aaron Williamson – a famous fitness trainer in the film and entertainment world who is known for bringing dramatic changes in the bodies of actors and athletes.

Aaron Williamson has designed two workout plans for JK Simmons.

The first one covers the chest abs and the back, while the second workout focuses on arms and abs.

Here are two different JK Simmons workout routines you can try if you want to train like this awesome actor.

Workout 1: Chest, Abs, And Back

The first JK Simmons workout is an upper-body focused workout that hits three muscle groups as well as abs:

  • Chest
  • Back
  • Abs
  • Shoulders

All the exercises in the workout have specific sets and reps, so nothing new there.

However, Simmons trains with a lot of supersets, and you should complete these with minimal rest to really push yourself.

At most, aim for 45 seconds of rest after you complete a set.

Warming-up is also necessary before moving on to the exercise. Try doing:

  • Some dynamic stretching exercises
  • Elliptical training at 140 BPM for at least 10 minutes

Once you’re done working out, you’re ready to hit the workout!

Here are the exercises and supersets you can follow for this first JK Simmons workout.

Exercise One:

  • Flat Dumbbell Press (4 x 10.)
  • Superset with flat reverse grip dumbbell press.

Exercise Two:

  • Machine Chest Press (4 x 10-12.)
  • Superset with cable crossovers.

Exercise Three:

  • Wide-Grip Lat Pulldowns (4 x 10-12.)

Exercise Four:

Exercise Five:
