Wondering just how much activity will give you a mental health boost? It’s probably not as much as you think. You don’t need to devote hours out of your busy day to train at the gym, sweat buckets, or run mile after monotonous mile. You can reap all the physical and mental health benefits of exercise with 30-minutes of moderate exercise five times a week. Two 15-minute or even three 10-minute exercise sessions can also work just as well.

Even a little bit of activity is better than nothing

If that still seems intimidating, don’t despair. Even just a few minutes of physical activity are better than none at all. If you don’t have time for 15 or 30 minutes of exercise, or if your body tells you to take a break after 5 or 10 minutes, for example, that’s okay, too. Start with 5- or 10-minute sessions and slowly increase your time. The more you exercise, the more energy you’ll have, so eventually you’ll feel ready for a little more. The key is to commit to some moderate physical activity—however little—on most days. As exercising becomes habit, you can slowly add extra minutes or try different types of activities. If you keep at it, the benefits of exercise will begin to pay off.

Can’t find time to exercise during the week? Be a weekend warrior

A recent study in the United Kingdom found that people who squeeze their exercise routines into one or two sessions during the weekend experience almost as many health benefits as those who work out more often. So don’t let a busy schedule at work, home, or school be an excuse to avoid activity. Get moving whenever you can find the time—your mind and body will thank you!

You don’t have to suffer to get results

Research shows that moderate levels of exercise are best for most people. Moderate means:

1. That you breathe a little heavier than normal, but are not out of breath. For example, you should be able to chat with your walking partner, but not easily sing a song.
2. That your body feels warmer as you move, but not overheated or very sweaty.

Overcoming mental health obstacles to exercise

So now you know that exercise will help you feel much better and that it doesn’t take as much effort as you might have thought. But taking that first step is still easier said than done. Exercise obstacles are very real—particularly when you’re also struggling with mental health. Here are some common barriers and how you can get past them.

Feeling exhausted. When you’re tired or stressed, it feels like working out will just make it worse. But the truth is that physical activity is a powerful energizer. Studies show that regular exercise can dramatically reduce fatigue and increase your energy levels. If you are really feeling tired, promise yourself a 5-minute walk. Chances are, you’ll be able to go five more minutes.

Feeling overwhelmed. When you’re stressed or depressed, the thought of adding another obligation can seem overwhelming. Working out just doesn’t seem doable. If you have children, managing childcare while you exercise can be a big hurdle. Just remember that physical activity helps us do everything else better. If you begin thinking of physical activity as a priority, you will soon find ways to fit small amounts into a busy schedule.

Feeling hopeless. Even if you’re starting at “ground zero,” you can still workout. Exercise helps you get in shape. If you have no experience exercising, start slow with low-impact movement a few minutes each day.

Feeling bad about yourself. Are you your own worst critic? It’s time to try a new way of thinking about your body. No matter your weight, age or fitness level, there are others like you with the same goal of getting fit. Try surrounding yourself with people in your shoes. Take a class with people at a variety of fitness levels. Accomplishing even the smallest fitness goals will help you gain body confidence.

Feeling pain. If you have a disability, severe weight problem, arthritis, or any injury or illness that limits your mobility, talk to your healthcare provider about ways to safely exercise. You shouldn’t ignore pain, but rather do what you can, when you can. Divide your exercise into shorter, more frequent chunks of time if that helps, or try exercising in water to reduce joint or muscle discomfort.

Getting started exercising when you’re anxious or depressed

Many of us find it hard enough to motivate ourselves to exercise at the best of times. When we feel depressed, anxious, stressed or have other mental or emotional problems, it can seem doubly difficult. This is especially true of depression and anxiety, which can leave you feeling trapped in a catch-22 situation. You know exercise will make you feel better, but depression has robbed you of the energy and motivation you need to work out, or your social anxiety means you can’t bear the thought of being seen at an exercise class or running through the park. So, what can you do?

It’s okay to start small. In fact, it’s smart.

When you’re under the cloud of an emotional disorder and haven’t exercised for a long time, setting extravagant goals like completing a marathon or working out for an hour every morning will only leave you more despondent if you fall short. Better to set achievable goals and build up from there.

Schedule your workout at the time of day when your energy is highest

That may be first thing in the morning before work or school,  at lunchtime before the mid-afternoon lull hits, or for longer sessions over the weekend. If depression or anxiety has you feeling tired and unmotivated all day long, try dancing to some music or simply going for a walk. Even a short, 15-minute walk can help clear your mind, improve your mood, and boost your energy level. As you move and start to feel a little better, you’ll experience a greater sense of control over your well-being. You may even feel energized enough to exercise more vigorously—by walking further, breaking into a run, or adding a bike ride, for example.

Other tips for staying motivated when you’re also struggling with mental health

Focus on activities you enjoy. Any activity that gets you moving counts. That could include throwing a Frisbee with a dog or friend, walking laps of a mall window shopping, or cycling to the grocery store. If you’ve never exercised before or don’t know what you might enjoy, try a few different things. Activities such as gardening or tackling a home improvement project can be great ways to start moving more when you have a mood disorder—as well as helping you become more active, they can also leave you with a sense of purpose and accomplishment.

Be comfortable. Whatever time of day you decide to exercise, wear clothing that’s comfortable and choose a setting that you find calming or energizing. That may be a quiet corner of your home, a scenic path, or your favorite city park.

Reward yourself. Part of the reward of completing an activity is how much better you’ll feel afterwards, but it always helps your motivation to promise yourself an extra treat for exercising. Reward yourself with a hot bubble bath after a workout, a delicious smoothie, or with an extra episode of your favorite TV show.

Make exercise a social activity. Exercising with a friend or loved one, or even your kids, will not only make exercising more fun and enjoyable, it can also help motivate you to stick to a workout routine. You’ll also feel better than if you were exercising alone. In fact, when you’re suffering from a mood disorder such as depression, the companionship can be just as important as the exercise.
