The Minimal Exercise Needed to Stay Fit
Share
Staying fit doesn’t always require a full gym schedule or intense daily workouts. Whether you’re traveling, dealing with a busy life, or just want to maintain your current fitness level, there’s good news. Research shows that you can preserve your strength and endurance with a lot less exercise than you might think. This article explains how.
When Maintenance is the Goal
We all go through periods where life gets in the way of our training. Maybe you're on a work trip, caring for family, or just need a mental break. During these times, the goal shifts from improving performance to simply maintaining it. Knowing the minimum amount of exercise you need can help prevent losing progress while freeing up time and energy for other priorities.
The Key to Maintenance: Intensity Matters Most
One clear takeaway from the research is that exercise intensity is the most important factor when it comes to maintaining your fitness. You can reduce how often you work out and even cut your sessions short, but you need to keep your workouts challenging.
How to Maintain Endurance
If you want to keep your cardiovascular fitness and endurance (like running or cycling ability), here’s what the research suggests:
- Frequency: You can train as little as 2 days per week.
- Duration: Sessions can be reduced to as little as 13 to 26 minutes, depending on your original volume.
- Intensity: You must maintain a high effort, ideally close to your usual heart rate during exercise.
Cutting back on how often or how long you train is okay, but lowering the intensity (e.g., switching to easy walks) is not enough to maintain performance.
How to Maintain Strength
To hold on to your strength gains, especially if you're lifting weights, you can also reduce your training load quite a bit:
- Frequency: Just 1 session per week is enough for most people.
- Volume: You only need 1 set per exercise.
- Intensity: You must continue using weights that challenge you—close to your usual max for that number of reps.
This approach works well for younger adults. Older adults may need 2 sessions per week and 2–3 sets per exercise to maintain muscle size.
Why This Matters for Everyone
Whether you’re a recreational athlete, a fitness enthusiast, or just someone trying to stay healthy, this minimalist approach can help you stay consistent during busy or difficult times. It’s especially useful for:
- Athletes during off-seasons or competitive periods
- Military personnel during deployment
- Busy professionals and parents
- Anyone recovering from burnout or injury
A Note of Caution
This strategy is about maintaining performance, not improving it. If your goal is to get stronger, faster, or build more muscle, you’ll need more frequency and volume. But when life gets hectic, knowing that just a little bit of focused effort can help you hold your ground is incredibly powerful.
Final Thoughts
You don’t have to lose your hard-earned fitness when life pulls you away from regular training. With as little as 1–2 sessions a week and a focus on keeping the intensity high, you can maintain both your endurance and strength for months. The next time your schedule gets tight, don’t quit—just scale down smartly. Less can truly be enough.
Let me know if you’d like a version tailored for a specific audience, like athletes, busy professionals, or older adults.
Can you stay fit with just one workout a week?
Yes, you can maintain your strength and endurance with much less exercise than expected. Just one or two intense sessions per week, even as short as 13 minutes, can help you keep your fitness levels. The key is to keep your workouts challenging, even if they're less frequent or shorter.
