Maintaining a healthy lifestyle isn’t easy. It’s not something you figure out once and forget about. It requires an immense amount of discipline, adaptability, and patience, spread over years and years of everyday life. As you get older, maintaining your level of health and fitness gets trickier.

Things will change with time, so be ready to adapt. These 5 habits will give you a baseline, and hopefully, keep you fit forever.

1. Stick to a solid sleeping schedule

Don’t underestimate the importance of getting a good night’s rest. Sleep is when your body recovers — whether it’s from exercise, stress, or something else entirely. Getting a solid amount of sleep every night has been linked to higher productivity, increased ability in the gym, and higher levels of mental activity. In short, sleep is important.

2. Follow an easy morning routine

The morning — or whenever you wake up — may be the most important part of your day. That’s why you need to develop a routine, keep it, and use it as a springboard to set you off for another round of victories, says Mark’s Daily Apple.

A morning routine can be simple — shower, eat a healthy breakfast, make your bed, and you’re off. Maybe mix in some meditation.

3. Concentrate on your diet

Many of us struggle to control our diet, but one easy way to do so is to concentrate on the things we eat. That is, centralize your diet around a select group of foods, and only occasionally stray from your plan. U.S. News & World Report suggests constructing a diet that’s vegetable-based — not necessarily vegetarian or vegan, but heavy on the greens — and not so dependent on meats, breads, and fats.

4. Find ways to relieve stress

You’re going to need to find a way to decompress or blow off some steam. Some like to go to the shooting range or play pickup basketball or soccer. A great habit to get into is weight lifting or running to relieve stress. Other fantastic, stress-relieving habits to pick up are meditation and yoga

5. Drink more water

Not drinking enough water can lead to mental and physical fatigue. Research also suggests drinking more water throughout the day can help you lose weight. Many people often confuse hunger and thirst, and end up eating more than they need to because they reach for food instead of a glass of water.
