Wondering whether your gym routine is too strenuous or too lenient? While we’ve covered how to control the intensity of your workouts, another key factor is the duration of your exercise sessions. The ideal workout length varies based on your fitness objectives and the type of activities you’re engaging in.
When time is tight
If you’re posing this question due to uncertainty about finding, for instance, an hour to exercise, here’s some encouraging news: Even a brief workout is far superior to skipping it entirely.
Previously, the exercise guidelines for Americans stipulated that only workouts lasting 10 minutes or more were valid. However, this rule was removed in 2018, meaning even shorter activities now contribute to your fitness goals.
Looking for inspiration? Beyond a brisk walk around the neighborhood, consider incorporating “fitness snacks” such as one of these 5-minute workout ideas. Alternatively, focus on mastering a specific exercise, like pull-ups, by practicing the “greasing the groove” technique and distributing your repetitions throughout the day.
If your goal is to boost cardiovascular fitness
Now, let’s explore what you can achieve if you do have time for a more conventional workout. For instance, how much time should you allocate to enhance your aerobic capacity and enjoy all the benefits for heart health?
For steady-state activities like jogging or cycling, aim for at least 20 minutes per session to make it effective. Thirty minutes is often ideal for routines performed several times a week—three 30-minute sessions total 90 minutes, aligning with the US guidelines of 75 to 150 minutes of weekly cardio. Five 30-minute sessions also create a consistent weekday exercise habit.
However, there’s no need to stick strictly to 30 minutes. Many fitness classes run for 45 or 60 minutes, which is equally effective. A cardio session lasting between 30 and 60 minutes is an excellent choice that fits into most schedules.
Interested in extending your workout? Engaging in low-intensity cardio activities, such as hiking or light jogging, for 90 minutes or more can significantly enhance your cardiovascular endurance. These longer sessions are typically reserved for once a week. For instance, a running plan might include 30-minute runs several times a week, complemented by a 90-minute long run on weekends.
Prefer to maximize your cardio in minimal time? High-intensity interval training (HIIT) is an excellent option, provided it’s genuine HIIT and not just a misleading label on a YouTube video. The intense Tabata protocol, for example, lasts just four minutes, while other HIIT routines typically wrap up in 10 minutes or less. Including a five-minute warmup and cooldown, the entire session can be completed in 15 to 20 minutes.
If your focus is on strength training
The duration of weightlifting sessions varies based on your objectives and the structure of your training plan.
For beginners, dedicating 30 minutes to exercise three times a week is often sufficient to start noticing progress. More seasoned individuals might still opt to divide their routine into daily 30-minute segments rather than committing to fewer, longer sessions each week.
When lifting heavy weights with the goal of maximizing strength gains, your workouts will naturally require more time per exercise. This includes performing warm-up sets to gradually reach your target weight and allowing 3–5 minutes of rest between sets for major compound movements like squats and deadlifts. As a result, a single squat session alone could take up to 30 minutes. Consequently, these strength-focused routines can span anywhere from one to two hours.
Thus, lifting workouts can range from 30 minutes to two hours, depending on your approach. To minimize gym time, consider pairing exercises in supersets and focusing on shortening rest intervals between sets.
In addition to benefiting your heart, cardio can enhance your body’s ability to recover faster between sets. While you won’t be able to perform deadlifts consecutively with just two minutes of rest, improving your conditioning could help reduce rest periods from eight minutes to five or enable you to complete isolation exercises like curls with only one minute of rest instead of two or three.
Tips for maximizing efficiency without compromising your workout
We’ve also compiled time-saving gym tips to help streamline your workouts if they’re taking longer than necessary.
Remember, combining strength training and cardio—even in the same session—can help you maximize both. With just an hour to spare, you can fit in a 30-minute weightlifting routine followed by 30 minutes on the treadmill.
It’s also worth evaluating how you spend your workout time to ensure efficiency. If your gym commute is lengthy, you take a long time to shower afterward, or you spend excessive time chatting with friends between sets, what could be a 90-minute workout might stretch to three hours.
Be realistic about your schedule, but understand that strict efficiency isn’t always necessary unless you’re pressed for time. Perhaps those gym conversations are the highlight of your day, or maybe allowing yourself a full hour instead of rushing through 45 minutes could lead to better progress.
