The Official 'Bare Minimum' for Health
Before setting personal goals, it's useful to know the global standard. Health organisations like the WHO provide clear guidelines for adults to maintain general health. The baseline recommendation is at least 150-300 minutes of moderate-intensity aerobic
activity per week. Think of this as anything that gets your heart rate up, like a brisk walk, cycling on a flat surface, or even vigorous house cleaning. Alternatively, you can aim for 75-150 minutes of vigorous-intensity activity, such as running, swimming laps, or a HIIT class. In simple terms, that’s about 30 minutes of moderate activity five days a week. Additionally, guidelines recommend including muscle-strengthening activities that work all major muscle groups on at least two days a week.
What 'Minimum' Looks Like in a Real Week
Knowing the numbers is one thing; fitting them into a packed schedule is another. The key is to see the 'minimum' not as a failure, but as a non-negotiable foundation for your health. For someone with a demanding schedule, hitting the minimum could look like this: three 30-minute brisk walks during lunch breaks or after dinner, plus two 20-minute full-body strength sessions at home using bodyweight exercises or dumbbells. These short sessions maintain the habit, which is far more important than intensity when you're starting out or time-crunched. The goal of the minimum is not dramatic transformation but health maintenance and, crucially, building the habit of regular movement.
Setting Your 'Target' for Real Progress
While the minimum keeps you in the game, the 'target' is what helps you win. Target sessions are what you plan when your goal is specific progress, such as building muscle, significant fat loss, or training for an event. For more substantial health benefits and visible progress, experts suggest aiming for the higher end of the scale, such as 300 minutes of moderate-intensity cardio. For strength training, progressing from two to three or four sessions a week allows for more focused work on different muscle groups and greater stimulus for growth. A target plan might involve three to four dedicated strength training sessions and two to three cardio sessions weekly, with adequate rest. This is the 'ideal week' you aim for, while accepting that on busy weeks, falling back to your minimum plan is a victory in itself.
Strength Training: From Two to Three Sessions
Strength training is often the first thing to be dropped, but its benefits for metabolism and bone density are immense. For the minimum, two full-body workouts per week are highly effective, hitting all major muscle groups each time. A session might include squats, push-ups, rows, and planks. When you're ready to make it a target, moving to three sessions a week offers more flexibility. You could continue with three full-body days for more frequency or adopt a split like 'Push/Pull/Legs', dedicating a full session to each group. This allows for more volume and intensity on each muscle, accelerating strength and muscle gains.
Make Your Plan Stick: Consistency Over Intensity
The best workout plan is the one you can stick to. An overly ambitious plan often leads to burnout and injury. The beauty of a minimum/target approach is its flexibility. Schedule your workouts in your calendar like any other important appointment. On a good week, you hit your target sessions. On a chaotic week, you hit your minimums and protect your habit. Remember that consistency beats sporadic intensity every time. A 20-minute workout done consistently is far better than a two-hour gym session that happens once a month. Use 'micro-workouts'—short 10-minute bursts of activity—to fill gaps and keep your body moving on days when even a minimum session feels impossible.
