How Quickly Do We Lose Fitness When We Stop Exercising? Why Starting Again Matters More Than Starting Over
Most of us have experienced it at some point. You get into a good routine, you're walking regularly, going to the gym, or simply feeling more active, and then life happens. You get sick, go on vacation, work gets busy, or you just fall out of the habit for a while.
When you finally get back to it, everything feels a little harder than you remember.
The walk that used to feel easy leaves you more winded. The weights feel heavier. Your legs get tired sooner, and suddenly you're wondering how you managed to lose your fitness so quickly.
The simple answer is that our bodies are very good at adapting to what we ask of them. When we exercise regularly, the body adapts by becoming stronger and more efficient. When we stop giving it that challenge for an extended period, some of those adaptations begin to fade. This is sometimes called detraining.
The good news is that losing some fitness doesn't mean you've lost everything you've worked for.
Different Parts of Fitness Change at Different Rates
Fitness isn't one single thing. Cardiovascular endurance, muscle strength, balance, flexibility, and mobility all respond differently when our activity levels change.
Aerobic fitness can begin to decline relatively quickly when regular exercise stops. That may be why people often notice their endurance first. You might find yourself breathing harder on a hill or feeling more tired during an activity that was comfortable a few weeks earlier.
Strength tends to be somewhat more resilient, particularly if you've been training consistently for a long time. Even so, extended periods of inactivity can eventually lead to losses in strength and muscle, something that becomes increasingly important to pay attention to as we get older.
There is also a big difference between taking a break from structured exercise and becoming completely inactive. You may not be going to the gym for a few weeks, but if you're still walking, gardening, doing yard work, climbing stairs, and generally moving throughout the day, your body is still being asked to work.
That's another good reason to remember that exercise doesn't only happen in a gym.
Taking Time Off Isn't Always a Bad Thing
I think we also need to be careful not to treat every break from exercise as a problem.
Rest and recovery are important. If you're sick, injured, exhausted, or simply need some time away from your regular routine, taking a break can be exactly what your body needs. A vacation doesn't need to come with guilt because you missed your usual workouts.
The problem is usually not taking a week off.
It's when a week becomes a month, a month becomes several months, and eventually inactivity becomes the new routine.
That's something I think many of us can relate to. Once a habit is broken, getting started again can feel much harder than continuing would have been.
You Aren't Starting From Zero
Here's the part I find encouraging. If you've been active in the past, getting back into shape isn't necessarily the same as building fitness for the first time. Our bodies adapt remarkably well, and previous training can make it easier to regain some of the strength and fitness we've lost.
That doesn't mean we should jump right back into exactly what we were doing before the break. If you've been inactive for a while, your body may need some time to adjust. Starting with lighter weights, shorter walks, or fewer workouts and gradually building back up is often a much better approach than trying to make up for lost time in the first week.
There is no prize for making yourself so sore on Monday that you can't move on Wednesday.
What matters is getting back into the habit.
Consistency Beats Intensity
I've written quite a bit lately about healthy aging, and this is another area where the same lesson keeps appearing.
Consistency matters.
You don't have to exercise intensely every day to benefit from movement. A couple of strength sessions during the week, regular walks, and generally staying active can accomplish far more over time than an ambitious routine you can only maintain for a few weeks.
I think this becomes particularly important as we get older. The goal isn't necessarily to become faster, stronger, or fitter every year. Sometimes the goal is simply to maintain what allows us to live the life we enjoy.
We want to keep climbing the stairs comfortably. We want to carry our own groceries, work in the yard, travel, golf, play with our grandchildren, and get up from the floor without needing assistance.
Maintaining those abilities requires us to keep using them.
Just Start Moving Again
If you've fallen out of your routine recently, you don't need to punish yourself for it, and you certainly don't need an elaborate plan to begin again.
Go for a walk.
Pick up the weights again, even if they're lighter than they used to be.
Spend ten minutes doing something instead of waiting until you have an hour.
The first few workouts may feel harder than you remember, but that's okay. Your body is being reminded of something it already knows how to do.
One of the most useful things I've learned about health is that there's very little value in worrying about what we should have done yesterday. We can only decide what we're going to do today.
Fitness can fade when we stop using it, but it can also return when we start asking our bodies to work again.
So if it's been a while, don't worry about starting over. Just start.
Here's to staying active and continuing to use the bodies we've been given,
