Wilmer Valderrama has spent years playing Special Agent Nicholas Torres on NCIS, one of the busiest production schedules on network television.
Long days on set do not leave room for a leisurely two hour gym session.
That kind of schedule is exactly where circuit training tends to show up.
Reporting on Valderrama’s approach to staying fit describes a circuit style workout. It hits the whole body in a single session, rather than splitting muscle groups across separate days.
Who Is Wilmer Valderrama
Valderrama was born on January 30, 1980. He first became widely known for playing Fez on the sitcom That ’70s Show, which ran from 1998 to 2006.
He built a varied career after that show ended. His credits include the film Party Monster, voice work in Disney’s Encanto and Onward, and a long running role on NCIS starting in its fourteenth season in 2016.
Beyond acting, Valderrama has stayed active in philanthropy. He co-founded the nonprofit Harness in 2017 and has completed more than 46 USO tours supporting military personnel around the world.
What the Circuit Workout Reportedly Involves
Circuits move quickly from one exercise to the next, with little rest between movements. That structure keeps the heart rate elevated throughout the session while still building strength.
Reporting describes Valderrama mixing bodyweight movements with added resistance. Portions of his routine have been shown publicly, though a complete, detailed breakdown of every set and rep has not been laid out in one place.
That detail matters for accuracy. This article describes his training as it has been reported, not as a confirmed program published directly by Valderrama himself.
What is clear is the appeal of the format for someone with his schedule. One focused circuit session can cover strength, conditioning, and mobility together, instead of requiring several separate workouts across a week.
Why Circuit Training Fits a Packed Schedule
Filming a procedural drama like NCIS often means long, irregular days. Actors can be called to set early and held late, with little advance notice of exactly when a break will happen.
Traditional training splits assume a predictable schedule. A four or five day per week split, with each day targeting different muscle groups, works well when you know you will make it to the gym on a consistent pattern.
That predictability is a luxury many working actors do not have. Circuit training solves this by packing a complete workout into whatever window of time is actually available.
A tight forty five minute circuit can outperform a slower paced hour with long gaps between exercises.
That efficiency is part of why the format keeps showing up in busy people’s routines, on set and off.
The Science Behind Circuit Training
Circuit training’s reputation for efficiency is not just marketing. Research backs up the idea that it can match traditional strength training on several fronts.
A 2011 study published in the Journal of Strength and Conditioning Research, led by researcher Pedro Alcaraz, compared high resistance circuit training against traditional strength training in men who already trained regularly.
The study found the two approaches produced similar adaptations in strength and body composition over the training period.
In other words, circuits were not a lesser substitute for traditional lifting. They performed comparably, in less total time.
That time efficiency comes from minimizing rest between exercises. Traditional strength sessions often include two to three minutes of rest between sets, while circuits compress that down significantly, keeping the body working near continuously.
The tradeoff is intensity per exercise. Circuits generally use lighter loads than a dedicated strength session built around low rep, high weight sets, which is one reason circuit training pairs well with, rather than fully replaces, focused strength work over time.
How This Compares to General Fitness Guidance
The Physical Activity Guidelines for Americans recommend at least 150 to 300 minutes of moderate aerobic activity weekly.
They also call for muscle strengthening activity on two or more days.
A well built circuit routine can satisfy both recommendations within the same sessions. That dual benefit is a big part of why trainers recommend circuits so often for clients with limited time.
Hitting national guidelines through separate cardio days and separate lifting days may not be realistic for someone managing a television production schedule.
Circuits offer a practical middle path.
Circuits are not automatically superior to traditional training for every goal, though.
Someone chasing a specific strength or size target may still get better long term results from a more traditional, progressively loaded program.
Circuit Training and Consistency
A shorter, harder workout done consistently tends to beat a longer one done sporadically.
This idea shows up constantly in fitness research, not just in anecdotes about busy actors.
Consistency compounds over time. Three focused forty five minute sessions a week, done reliably for months, produce more progress than an ideal ninety minute plan that only happens once every two or three weeks.
This is where circuit training earns its reputation beyond just efficiency. It lowers the barrier to actually showing up, which matters more than almost any other variable in long term fitness.
For someone with an unpredictable schedule, that lowered barrier can be the difference between training regularly and not at all.
A short circuit that actually happens beats a perfect plan that gets skipped.
There is also a mental benefit worth mentioning. Knowing a workout can be finished in well under an hour removes a common excuse for skipping it entirely, especially on a demanding filming day.
Common Mistakes People Make With Circuit Training
The most common mistake is treating every circuit like an all out sprint from round one.
Pacing matters early on. Burning out in round one leads to a weaker performance across the rest of the session.
Skipping a warm up is another frequent error. Circuits move fast once they start, which makes a rushed or absent warm up more likely to cause strain, particularly in the shoulders and lower back.
People also tend to pick exercises that are all the same movement pattern. A circuit built entirely from pushing exercises, for example, leaves pulling muscles undertrained and can create imbalances over time.
Ignoring form under fatigue is a serious risk in circuit training. As rounds accumulate, form naturally starts to break down, and pushing through with poor technique raises injury risk significantly.
Finally, many people never progress their circuits. Doing the exact same rounds, weights, and rest periods indefinitely eventually stalls results, the same way any unchanging program does over time.
How to Build Your Own Circuit Workout
Pick five to seven exercises that cover different movement patterns. A balanced circuit typically includes a squat or lunge variation, a push, a pull, a hip hinge like a deadlift, and a core movement.
Set a work to rest ratio that fits your fitness level. Beginners often do well with thirty seconds of work and thirty seconds of rest, while more advanced exercisers can push toward forty five seconds of work with fifteen seconds of rest.
Complete the full circuit two to four times through, depending on your time and conditioning level.
Rest for one to two minutes between full rounds of the circuit, not just between individual exercises.
Use a mix of bodyweight and added resistance. Explosive bodyweight movements like box jumps pair well with dumbbells or kettlebells in the same circuit, giving you both power and strength stimulus.
Warm up properly before starting. Five to ten minutes of light cardio and dynamic movement prepares your joints and muscles for the fast pace that follows.
Track your circuits over time. Writing down your rounds, weights, and how you felt lets you progress deliberately instead of guessing whether you are actually improving.
If your schedule does not allow for a full circuit some days, do not treat rest days as wasted time.
A short walk or mobility session on an off day still supports recovery and keeps the habit consistent.
If you are unsure how to structure a safe, balanced circuit on your own, working with a trainer for a session or two can help you build a template you can then run independently.
A Sample Full Body Circuit
This is a simple starting template, not a copy of any specific celebrity routine. Adjust the exercises, weights, and timing to match your own fitness level.
Start with bodyweight squats for forty five seconds, followed by fifteen seconds of rest. This wakes up the legs and raises the heart rate right away.
Move to push ups for forty five seconds, then rest fifteen seconds. Modify on your knees if needed, since form matters more than reps here.
Follow with dumbbell or resistance band rows for forty five seconds, then rest fifteen seconds.
This balances out the pushing work from the push ups.
Add a hip hinge movement next, like a kettlebell deadlift or hip thrust, for forty five seconds, then rest fifteen seconds.
This trains the glutes and hamstrings, which pushing and pulling exercises tend to miss.
Finish the round with a core movement, like a plank or slow mountain climbers, for forty five seconds.
Rest one full minute before starting the next round.
Repeat the entire five exercise circuit two to four times, depending on your conditioning.
A well paced version of this template takes about twenty to thirty minutes total.
Once this feels manageable, increase the challenge gradually. Add resistance, extend the work intervals, or add a sixth exercise rather than jumping straight to a much harder version all at once.
