How Long Should My Workouts Last? Finding the Right Duration for Your Fitness Goals
When it comes to fitness, one of the most common questions people ask is: "How long should my workouts last?"Whether you're aiming for fat loss, muscle gain, improved endurance, or simply maintaining a healthy lifestyle, the answer to this question varies based on your individual fitness goals. Understanding how long you should be working out for the best results is essential to creating an effective exercise routine.
In this blog, we'll break down the ideal workout duration for different fitness objectives, backed by research from leading health and fitness organizations like the National Institutes of Health (NIH), Academy of Nutrition and Dietetics (AND), and the American College of Sports Medicine (ACSM).
General Guidelines: How Much Exercise Do You Really Need?
The American College of Sports Medicine (ACSM) recommends that adults should aim for at least 150 minutes of moderate-intensity aerobic exercise per week or 75 minutes of vigorous-intensity exercise. This is roughly equivalent to 30 minutes a day, five days a week. However, this baseline recommendation is just the starting point. Depending on your goals, you might need to adjust the duration and intensity of your workouts.
1. Fat Loss: How Long Should Your Workouts Be?
If your primary goal is to shed fat, the duration of your workouts will depend on both your exercise type and intensity.
Duration for Fat Loss:
For fat loss, studies suggest that longer, moderate-intensity sessions can be beneficial. According to the NIH, working out for 30-60 minutes, 4-5 times a week, can help create the calorie deficit needed for weight loss. Combining both cardiovascular exercises (like running or cycling) and strength training (like weightlifting or bodyweight exercises) is especially effective in maximizing fat loss while preserving muscle mass.
Intensity Matters: Higher-intensity interval training (HIIT) has also been shown to be effective in burning fat in shorter periods. If you only have 20-30 minutes to work out, a HIIT session could still lead to impressive fat loss results.
However, moderate-intensity cardio performed over a longer duration—like 45 minutes of jogging—may help burn fat more efficiently, especially when paired with a healthy diet.
2. Muscle Building: How Long Should You Train for Hypertrophy?
When your goal is to build muscle (hypertrophy), the focus shifts to strength training, but how long should you be lifting weights for optimal gains?
Duration for Muscle Gain:
Most studies, including those reviewed by the Academy of Nutrition and Dietetics (AND), suggest that strength training workouts last anywhere from 45 to 90 minutes per session for maximum hypertrophy. Longer sessions are typically necessary when doing multiple sets and compound movements (such as squats, deadlifts, and bench presses) that recruit larger muscle groups.
It’s important to note that the overall time doesn’t need to be excessive; rather, it’s the intensity (weight load, rest periods, and the volume of sets) that should be manipulated for muscle growth.
Rest Periods and Recovery: Rest periods of 60-90 seconds between sets are generally recommended for hypertrophy. Longer rest periods (up to 3 minutes) might be required if you're focusing on maximum strength rather than muscle size.
3. Endurance Training: How Long Should You Run or Cycle?
For endurance training—whether you’re a runner, cyclist, or swimmer—the duration of your workouts is key to improving your stamina and cardiovascular health.
Duration for Endurance:
Endurance athletes typically train for 60-120 minutes per session, with longer sessions being more common for long-distance runners and cyclists. According to the NIH, if you're training for events like marathons or triathlons, your weekly training volume can range between 6-12 hours, with long weekend sessions pushing towards the 2-3 hour mark.
For beginners, shorter sessions around 30-60 minutes, 3-4 times per week, should be sufficient to build endurance over time.
4. Health Maintenance: How Long Should You Exercise to Stay Healthy?
If you’re simply looking to stay healthy and maintain general fitness, shorter sessions may be enough to achieve your goals.
Duration for Health Maintenance:
According to the ACSM, 150 minutes of moderate-intensity exercise or 75 minutes of vigorous-intensity exercise per week is sufficient for maintaining cardiovascular health and muscle strength. Breaking this down into 30-minute sessions, five days a week, is an easy and effective way to maintain overall fitness.
For those with time constraints, even 20-minute workouts can help you stay healthy if you're consistently active throughout the week.
Finding Your Ideal Workout Duration
The right workout duration depends on your specific fitness goals. Here’s a quick recap of how long you should aim to work out based on your objectives:
- Fat loss: 30-60 minutes, 4-5 times per week (moderate-intensity cardio and strength training)
- Muscle building: 45-90 minutes, 3-5 times per week (strength training with proper intensity)
- Endurance: 60-120 minutes, 3-5 times per week (longer cardio sessions)
- Health maintenance: 30 minutes, 5 times per week (moderate-intensity exercise)
Remember, consistency is key! Even with the best workout plan, achieving your fitness goals requires dedication and patience.
