Concurrent training combines resistance work and cardiovascular work either inside one session or across the same week. The mechanism is additive: cardio raises immediate energy expenditure, while resistance training recruits muscle and supports a higher long-term metabolic demand. A same-session version alternates short aerobic intervals with paired strength exercises so the trainee keeps moving; a weekly version alternates full-body strength days with core-and-cardio days. Greenfield acknowledges an interference effect—neither quality is developed as purely as it would be alone—but argues that the combined metabolic stimulus is the stronger trade-off when fat loss is the goal. The method should still be scaled to recovery capacity, because more intensity is not automatically better.
Origin
Ben Greenfield described concurrent training on Habits & Hustle as his preferred way to combine metabolic stimulus, strength, and cardio when time is limited.
Core principles
- 01Total energy use matters more than the percentage of fat burned in the moment
- 02Strength and cardio provide complementary adaptations
- 03Intensity can keep metabolic demand elevated after training
- 04Consistency still outranks a theoretically perfect workout
How to run it
- 1
Set the primary goal
Use this framework when fat loss and broad metabolic fitness matter more than maximizing a single athletic quality.
Pro tip Define the goal before choosing the room temperature, interval length, or exercise selection.
Watch out Specialist strength or endurance athletes may need more separated training blocks.
- 2
Choose the format
Either alternate cardio and strength inside one workout or alternate strength and cardio days across the week.
Pro tip Use the same-session version when travel or schedule pressure limits training time.
- 3
Build complementary blocks
Pair short aerobic efforts with compound or paired resistance exercises that cover the major movement patterns.
Pro tip A two-minute cardio interval between strength supersets is the episode's concrete template.
Watch out Do not let fatigue degrade lifting technique.
- 4
Keep metabolic demand high
Move steadily through the session rather than turning every rest period into passive downtime.
Pro tip Select transitions and equipment that make the circuit practical in the available gym.
Watch out Continuous movement does not require maximal intensity in every block.
- 5
Monitor recovery
Watch multi-day trends in resting heart rate, temperature, sleep, appetite, and swelling, then reduce load if several signals deteriorate.
Pro tip Treat a pattern lasting roughly three days as more informative than one unusual day.
Watch out Persistent or severe symptoms warrant qualified medical assessment.
In the wild
Greenfield alternates two minutes on an Airdyne with chest press and push-ups, then repeats the pattern with leg press and hamstring curls, overhead press and band pull-aparts, and lat pull-downs and seated rows.
→ One session supplies aerobic work, full-body resistance work, and sustained metabolic demand.
Greenfield's weekly version places full-body strength on Monday, Wednesday, and Friday, with core and cardio on Tuesday, Thursday, and Saturday.
→ Strength and aerobic stimuli accumulate across the week without occupying the same session.
Common mistakes
Optimizing fat percentage instead of total burn
Low-intensity work may burn a higher percentage of fat while producing too little total energy expenditure to be the most efficient fat-loss session.
Ignoring the interference trade-off
Concurrent work is a goal-specific compromise, not the best way to maximize pure strength or pure endurance.
Turning intensity into chronic overload
Excessive high-intensity volume can eventually impair recovery and undermine the intended result.
Is it for you?
Best for
It is best for healthy exercisers who want body-composition results from limited training time.
Not ideal for
It is not ideal for athletes whose immediate priority is maximizing one specialized strength or endurance quality.
From the transcript
“Concurrent training, meaning doing strength and cardio at the same time, either in the same workout or throughout the week, is the most superior form…”
“both put together for fat loss and the metabolic stimuli are gold standard and that's called concurrent training.”
“the best workout is the workout you're actually going to do.”
