The myth of long workouts

Many people believe that you need to spend hours in the gym to see meaningful fitness results. While long workouts can be effective, research shows that shorter, high-quality workouts can deliver similar benefits, sometimes even more efficiently.

If you have a busy schedule or struggle to commit to long training sessions, the good news is that you do not need marathon workouts to get fitter, stronger, or healthier. What matters most is consistency, intensity, and quality.

Let’s break down the science behind why short workouts can be just as effective as longer ones.

Short workouts, big benefits

Even brief exercise sessions can lead to improved fitness, longevity, and overall health.

• 20–30 minutes of moderate to intense exercise can provide significant health benefits.
• As little as 75 minutes of exercise per week has been linked to an increased life expectancy of 1.8 years.
• Short workouts can boost strength, endurance, and cardiovascular health without requiring long gym sessions.

The key takeaway: it is not about how long you work out, it is about how well you use your time.

HIIT: the power of short, intense workouts

High-intensity interval training (HIIT) is one of the best examples of short workouts delivering big results. HIIT involves short bursts of intense effort followed by brief rest periods, making workouts more time-efficient while maintaining effectiveness.

• Studies show that just 20-minute HIIT workouts can significantly improve fitness.
• Men in their late 60s reduced their biological age by 20 years with just 20 minutes of HIIT cycling.
• HIIT can improve cardiovascular health, metabolism, and endurance, even in older adults.

If you want to maximise results in minimal time, HIIT is one of the most effective approaches.

Strength training: less time, same gains?

You do not need long strength-training sessions to build muscle and improve strength. Research on minimum effective dose training found that:

• One set of 6–12 reps per exercise can lead to noticeable strength gains.
• While multiple sets enhance strength further, long training sessions are not required for progress.
• Short, focused strength sessions can still improve muscle tone, endurance, and overall fitness.

If time is a concern, a well-structured 20–30-minute strength session can still be highly effective.

What matters more than duration?

Rather than focusing on how long you work out, prioritise:

• Consistency: Regular workouts, even short ones, lead to long-term success.
• Workout quality: A focused 20-minute session is better than an unfocused 60-minute one.
• Balanced training: Combining cardio and strength for overall fitness.
• Proper recovery: Rest, nutrition, and sleep matter as much as exercise.

Final thoughts

The idea that you need long workouts to see results is outdated. Science shows that shorter, well-structured sessions can be just as effective.

If you are struggling to fit exercise into your schedule, remember that quality beats quantity. A 20–30-minute focused workout can provide lasting benefits, helping you stay fit, healthy, and strong without spending hours at the gym.

The best workout is the one you can do consistently, no matter how long it lasts.
