A Women’s Health interview with actor Alison Brie and trainer Jason Walsh described using brief isometric efforts before repetitions of the same movement. Fit&Well’s report also offers a four-exercise home workout from trainer Mark Harris, though the supplied report cuts off before giving the full routine and does not establish that this method alone caused Brie’s strength gains.
Alison Brie’s trainer Jason Walsh uses a technique that pairs a forceful, motionless hold with repetitions of the same exercise, according to an interview with the actor published by Women’s Health and summarized by Fit&Well. The report outlines the approach and introduces a four-exercise home workout from coach Mark Harris, but it does not show that the technique alone produced Brie’s strength gains.
In Walsh’s example, Brie first pushes as hard as she can against a fixed bar while positioned for a Zercher squat, then performs Zercher squats with a barbell. An isometric hold contracts the muscles without changing the joint position; the following repetitions move through the exercise. Walsh said the combination can recruit the nervous system strongly and may help build strength without adding size. That is his explanation of the method, not evidence in the supplied report that the same outcome is guaranteed for other people.
Fit&Well says Brie began strength training about 15 years ago, after working with actor Emily Blunt, and increased her training while preparing to play a wrestler in the series GLOW. The report gives weighted pull-ups with 45-pound plates as one example of her current training. It attributes the workout technique to Walsh’s account of her routine; it does not isolate the effect of isometrics from her broader training history.
For readers seeking a home option, Harris recommends performing a hold and then moving straight into repetitions before proceeding to the next exercise, with minimal rest between pairs. His plan calls for four exercises, followed by 60 to 90 seconds of rest after each circuit, for four rounds in total. The supplied source lists a goblet squat hold for 30 seconds followed by 10 squats, a push-up hold for 10 seconds followed by 10 push-ups, and a bent-over row hold for 15 seconds followed by 10 rows. The provided material ends during the row instructions and does not identify the fourth exercise.
How Holds Change a Strength Set
The approach gives a clear structure to a strength session: hold a position under tension, then perform controlled repetitions of the same movement. For people who find conventional sets difficult to adapt, Harris’s plan includes a kneeling push-up option and a body-weight-free choice to use dumbbells for rows, making some adjustments possible at home.
Harris says isometric work can help people focus on a difficult position in a lift and brace their core. Those are coaching claims in the report, rather than demonstrated results from a trial described in the source. Brie’s routine also involves years of training and substantial loads, so her performance should not be treated as a typical starting point or a promise of what a short workout will achieve.
The practical takeaway is modest: holds can be added to familiar strength movements, but effort and load should match a person’s experience. The supplied material does not offer a progression plan or specify how often to do the workout.

Brie’s Training Before the Workout
The report connects Brie’s strength work to roles that called for physical preparation. She told Women’s Health she started lifting roughly 15 years earlier after working with Emily Blunt, then trained more while preparing for GLOW. Fit&Well identifies her as 43 and notes that Walsh has worked with her on training.
The article moves from that celebrity example to advice for general readers by asking Harris, a level 4 personal trainer and strength and conditioning coach, to propose an accessible home session. The two parts should be distinguished: Walsh describes Brie’s training, while Harris supplies the suggested workout. The report does not say Brie performed Harris’s circuit.
“It recruits the nervous system at such a high rate that you can get really strong without getting bigger.”
— Jason Walsh, Alison Brie’s trainer, as quoted in the Fit&Well report
The Workout Details Still Missing
The source material supplied for this article stops partway through the bent-over row instructions. It names three hold-and-repetition pairs but not the fourth exercise, despite describing a four-exercise circuit. The complete workout therefore cannot be reproduced from the material available here.
The report also does not provide a study, comparison group, or measured results showing how much strength the technique adds, whether it reduces joint wear, or whether it changes muscle size. Walsh’s and Harris’s explanations remain attributed coaching statements. It is also unclear how often Harris expects people to repeat the session across a week, or how participants should increase resistance over time.
Use the Method at Your Level
Readers interested in trying the method can use the reported sequence only with the exercises and instructions available: a hold, then controlled repetitions, adjusting the movement to their ability. Harris’s instructions allow push-ups from the knees. The report advises moving between pairs with minimal rest and resting 60 to 90 seconds after a completed circuit, but it does not supply the missing fourth pair or a weekly schedule.
Start with a manageable load and stop if an exercise causes pain; people with injuries, health conditions, or uncertainty about technique should seek guidance from a qualified professional before starting or changing a strength routine. The next useful detail would be the complete workout and any guidance on scaling it. The supplied report does not indicate when that information may be available.
Key Questions
What is the workout technique described?
It pairs an isometric hold—contracting muscles without moving the joint—with repetitions of the same exercise immediately afterward. Walsh describes using it with a Zercher squat for Brie.
Does the report say isometric holds made Brie strong?
No. It describes the technique used by her trainer and reports that Brie has trained with weights for years, including more while preparing for GLOW. It does not establish that isometric holds alone caused her strength.
What exercises are included in the home workout?
The available source lists a goblet squat hold and squats, a push-up hold and push-ups, and a bent-over row hold and rows. It says the circuit has four exercises, but the provided text cuts off before naming the final one.
How many rounds does the suggested circuit use?
Harris’s reported instructions call for four rounds, with 60 to 90 seconds of rest after all four exercises. The source does not give a weekly schedule.
Can beginners adapt the workout?
The reported instructions offer kneeling push-ups as an easier variation. Choose loads and movements appropriate to your ability, and seek qualified guidance if you have an injury or health condition or are unsure about safe form.
