Fit&Well published a first-person report testing a four-move upper-body routine that celebrity trainer Megan Roup performed with Karlie Kloss. The reporter used 2kg dumbbells, completed three rounds in about 12 minutes, and said the repeated punches felt challenging by the final round.
Fit&Well has published a reporter’s account of trying a four-move upper-body workout that trainer Megan Roup performed with model Karlie Kloss, finding that 2kg dumbbells made the repeated punching exercises feel demanding. The tester completed three rounds in about 12 minutes, offering a personal example of how a short, light-weight routine can still feel strenuous—not a controlled test of its effects on strength or fitness.
Roup, founder of The Sculpt Society, shared the routine in an Instagram reel, according to Fit&Well. It consists of triceps punches, overhead punches, diagonal punches and cross-center punches. Roup’s recommended format, as reported by the outlet, is two to three rounds of 16 repetitions per exercise. For alternating movements, the reporter counted eight repetitions on each arm; for cross-center punches, 16 repetitions total.
The reporter did not have the same hand weights shown in the reel and instead used 2kg (about 4.4lb) hex dumbbells. They completed three rounds of all four moves, resting for 60 seconds between rounds. The session took about 12 minutes including those rests. The writer said the repetition count accumulated in difficulty and that the weights felt almost too heavy by the third round.
Fit&Well’s account is a single person’s workout experience. The reporter also said the routine seemed to emphasize the triceps and that diagonal punches were their preferred movement. The article suggests reducing repetitions to eight to 10 or trying the movements without weights if the suggested volume feels excessive. Those are options described in the source, not individualized training advice.
A Short Routine That Builds Effort
The report illustrates that light weights do not automatically mean low effort: repeated movements can become challenging over several rounds, as the tester described. For readers looking for a brief arm session, the routine offers a concrete format—four movements, repeated sets and optional rest—rather than a claim that a particular celebrity workout produces a specific result.
The tester connected the moves to triceps and shoulder endurance and said the punching pattern made the session feel engaging. Those observations describe their experience; the source does not provide measurements of muscle growth, calorie expenditure or fitness changes. The distinction matters because a workout report can show what one participant found difficult without establishing what others will experience or what results the routine will deliver.
Fit&Well also notes that the triceps contribute to pushing actions, such as pushing a door or rising with help from chair armrests. That practical context helps explain why someone might train the back of the upper arm, beyond appearance. The article does not claim the routine alone improves those activities.

How Roup’s Four Moves Are Structured
The routine is attributed to Megan Roup, a celebrity trainer and founder of The Sculpt Society. Fit&Well says her clients include Dakota Johnson and Sabrina Carpenter; that background identifies the trainer but does not independently verify how the workout affects participants. Kloss is the person shown performing the routine with Roup in the Instagram reel described by the outlet.
The prescribed structure is two to three rounds of 16 repetitions per exercise. The reporter chose the upper end, used 2kg dumbbells and rested for one minute between rounds. For alternating exercises, the 16 repetitions were divided between arms; for cross-center punches, the writer performed 16 total. The source does not specify a tempo or a precise duration for each movement.
The tester’s account also puts the routine in a personal fitness context: they were looking for a short workout and had previously enjoyed boxing-style exercise. They described the controlled punches as a welcome break from desk work. That motivation is part of the reporter’s experience, not evidence that the routine has a particular stress-relief effect for everyone.
“The dumbbells almost felt too heavy by round three.”

What the Workout Report Cannot Show
The article does not report independent testing, participant measurements or a comparison group. It therefore cannot establish whether the routine builds strength or muscle, how it compares with other workouts, or whether the 2kg weights are appropriate for a different person. The claim that the session felt challenging applies to the reporter’s own trial.
Fit&Well’s source does not give a publication date, the exact weight of the hand weights used by Roup and Kloss, or a full movement-by-movement technique guide. It also does not report whether Kloss completed the same number of rounds or repetitions. The source offers an alternative of fewer repetitions or no weights, but does not set out personal modifications for injuries or other health considerations.
Repeating or Adapting the Session
The reporter said they planned to try the workout again, partly because they are working to improve their bench press and found the short session enjoyable. Fit&Well does not report a later follow-up or any measured change in that goal. Readers following the routine can use the reported structure as a description, while recognizing that the article does not establish a universally suitable weight or repetition target.
The source points readers who do not have dumbbells toward a separate 20-minute beginner shadowboxing routine, but it does not include that workout’s details in this report. No further results or changes to Roup’s routine are provided.
