Good news: the 'weekend warrior' counts too

A large cohort study published in JAMA Internal Medicine analyzed data from hundreds of thousands of people and found that concentrating an entire week's physical activity into one or two weekend sessions (the 'weekend warrior' pattern) was associated with a similarly reduced mortality risk as spreading the same amount of activity evenly across the week.

Association of the 'Weekend Warrior' and Other Leisure-time Physical Activity Patterns With Mortality

Moderate evidence

dos Santos M, Zhu W, Ferrari G, et al. · JAMA Internal Medicine · 2022

People concentrating their entire recommended weekly physical activity into one or two sessions ('weekend warriors') had similarly lower all-cause mortality risk as people active evenly throughout the week, provided they achieved a similar total amount of activity.

The minimalist principle: effectiveness over volume

With a limited time budget, priority should go to exercises engaging multiple muscle groups at once (squats, deadlifts, push-ups, pull-ups) rather than isolated single-muscle exercises — this gets you the maximum training stimulus with the fewest exercises and the least time.

Three compound exercises are enough to start

A combination of a squat, a push-up (or press) and a pull-up (or row) engages nearly all the major muscle groups and can form the core of an effective, short, full-body workout.

How many sets a week do you really need to build muscle

A meta-analysis by Schoenfeld and colleagues, covering data from dozens of studies, examined the relationship between the number of weekly training sets performed for a given muscle group and muscle mass gain — and showed that the benefit curve is clearly non-linear: the largest jump in effect comes from going from zero to a few sets a week, and each additional set added yields progressively smaller extra gains.

Dose-response relationship between weekly resistance training volume and increases in muscle mass

Strong evidence

Schoenfeld BJ, Ogborn D, Krieger JW · Journal of Sports Sciences · 2017

A dose-response analysis showed that even a small number of weekly sets per muscle group (on the order of a few) produces a noticeable increase in muscle mass, and the benefits from each additional set added gradually diminish — meaning a minimalist but consistent training plan isn't as much of a compromise as it might seem.

In practice, this means two short weekly sessions, performed close to effort failure on compound exercises, can deliver most of the available stimulus for strength and muscle mass growth — adding further hours of training per week brings a real, but progressively smaller, return on the time invested.

How to use HIIT with very limited time

Short high-intensity interval training protocols can produce significant cardiovascular and metabolic adaptations in just a dozen or so minutes, making them a particularly practical tool for people with very limited time — more on the mechanism and protocols of HIIT can be found in a dedicated knowledge base entry.

For active people

Training regularly? Check your supplement profile.

Sleep, diet, training frequency, and recovery all matter. Answer a few questions and see which supplements might make the most sense for you.

Recommendations take your answers and the strength of the scientific evidence into account. A supplement's popularity has no bearing on whether it gets recommended.

Your minimalist weekly checklist

A minimal but effective weekly plan

2 full-body strength training sessions of 20-30 minutes, based on compound exercises
1 short HIIT session (10-20 minutes) as a supplement
Daily, small amounts of movement (walking, stairs) as part of NEAT, requiring no dedicated time
One longer block of activity on the weekend, if the weekly goal wasn't met

Myth vs. Fact: does a short workout 'not count'?

Myth

If you don't have an hour for a workout, it's better not to work out at all.

Fact

Data from large cohort studies shows that even physical activity concentrated into one or two sessions a week is associated with a significant reduction in mortality risk — a short, focused workout has real value, it isn't a 'waste of time' compared with no activity.

Our editorial recommendation

A perfect, long training plan you never actually follow because of lack of time is worth less than a simple, minimalist plan consistently carried out every week. Start with two short sessions a week and build the habit before considering increasing volume.

The best training plan is the one you actually do — two consistent, 25-minute sessions a week beat any perfect plan that stays only on paper.

Frequently asked questions

Data from large cohort studies suggests that concentrating weekly activity into fewer, longer sessions can bring similar health benefits as spreading it out evenly, provided a similar total amount of activity is achieved.

A workout based on 3-4 compound exercises can be effectively completed in 20-30 minutes, especially with the right selection of exercises engaging multiple muscle groups at once.

With the right intensity and consistency, short but regular strength training sessions can produce real results, though the pace of progress may be slower than with a greater total weekly training volume.

He still runs, though these days, as he puts it, purely for the fun of it.

Beta-Alanine and Exercise Capacity: Who Does It Actually Work For?

Beta-alanine is one of the few pre-workout supplements whose effect can be felt almost tangibly — the characteristic skin tingling (paresthesia) after a dose leads many people to take effectiveness for granted. The largest available meta-analysis, covering over 1,400 participants and 65 different research protocols, shows something that requires real clarification: not every type of exercise responds to it the same way.

Fasted Training and Fat Loss: A Real Mechanism, a Wrong Conclusion?

Fasted training has a reputation as a "hack" for faster fat loss — and, rare in the world of popular fitness advice, the underlying mechanism itself is scientifically true. The problem is that the study testing whether this mechanism translates into a real, long-term difference in body composition gave an answer that undermines the entire rationale for this strategy as a weight-loss tool.

Phosphatidylserine and Post-Exercise Cortisol: Does This Supplement Really Blunt Training Stress

Phosphatidylserine is often marketed to athletes and people training intensely as a way to "calm down" cortisol after a workout and speed up recovery. Behind this claim stands a specific double-blind, placebo-controlled crossover study — small, but methodologically solid. We take a close look at exactly what it showed, and what it didn't, before you decide on this fairly costly supplement.

L-Carnitine and Fat Burning: Does the "Fat-to-Mitochondria Transporter" Actually Work?

L-carnitine has been sold for decades as a "fat burner" — a substance said to transport fat directly into mitochondria to be burned for energy. The biochemical mechanism is real, but a well-designed trial combining carnitine with aerobic training in women found no difference in fat loss versus placebo, while a meta-analysis of 37 trials shows only a modest, if repeatable, effect on body weight. We check what the data actually confirm versus what's just a logical but unproven marketing hypothesis.

Very clearly explained, especially the interactions section — I hadn't seen it laid out this well anywhere else.

Are you planning to update this with the newest study from this year? I saw an interesting meta-analysis.
