What are the best types of exercise?
1. Cardiovascular Exercise (Aerobic)
Cardio exercises are essential for improving heart health, increasing stamina, and burning calories. They involve activities that elevate your heart rate and engage large muscle groups. The most common forms of cardio include:
-
Running or Jogging: One of the most accessible forms of cardio. Running builds endurance and burns fat effectively.
-
Cycling: Both outdoor and indoor cycling are great for improving cardiovascular health and building leg strength.
-
Swimming: Provides a full-body workout while being gentle on the joints, making it ideal for people with joint pain or those recovering from injury.
-
Walking: A low-impact exercise that is easy on the joints but still promotes heart health, weight loss, and overall well-being.
Cardiovascular exercise helps improve lung capacity, reduces the risk of chronic diseases like heart disease and diabetes, and can contribute to weight loss when paired with proper nutrition.
2. Strength Training (Resistance Exercise)
Strength training is crucial for building muscle, increasing metabolism, and improving bone density. It involves using resistance, such as weights, resistance bands, or bodyweight, to challenge your muscles. Benefits include:
-
Weightlifting: Using dumbbells, barbells, or machines, weightlifting builds muscle mass, boosts metabolism, and strengthens bones.
-
Bodyweight exercises: Movements like push-ups, squats, lunges, and planks use your body weight for resistance. These exercises are great for beginners and can be done anywhere.
-
Resistance bands: These are portable and can be used for exercises that target various muscle groups, helping with strength building and muscle toning.
Incorporating strength training into your routine helps with functional movements, supports weight management, and reduces the risk of injury.

3. Flexibility and Mobility Exercises
Flexibility exercises, such as yoga and Pilates, enhance joint range of motion and prevent stiffness. Regular stretching improves muscle elasticity and helps with posture and balance. Notable options include:
-
Yoga: Combines breathing exercises, strength, flexibility, and relaxation. It can help reduce stress, improve posture, and enhance flexibility and mobility.
-
Pilates: Focuses on core strength, balance, and flexibility. It’s particularly beneficial for improving posture and preventing back pain.
Flexibility exercises reduce the risk of injury by promoting better movement mechanics and can aid in faster recovery from other workouts.
4. High-Intensity Interval Training (HIIT)
HIIT involves short bursts of intense activity followed by rest or low-intensity periods. This type of workout can be done with various exercises like jumping jacks, sprints, squats, or burpees. The benefits of HIIT include:
-
Time efficiency: HIIT workouts can be completed in as little as 20-30 minutes while still providing significant fitness improvements.
-
Fat burning: HIIT boosts your metabolism and continues to burn calories even after the workout is done, thanks to the afterburn effect (EPOC—Excess Post-Exercise Oxygen Consumption).
-
Cardiovascular health: Improves both aerobic and anaerobic endurance.
HIIT is excellent for those looking to maximize their results in a short period, improve cardiovascular fitness, and burn fat.
5. Balance and Coordination Exercises
Balance exercises are often overlooked but are important for maintaining stability, preventing falls, and improving overall coordination. Examples include:
-
Tai Chi: A low-impact, slow-motion practice that improves balance and flexibility.
-
Standing on one leg: Simple exercises like standing on one leg while maintaining balance can improve coordination and core stability.
These exercises are particularly important for older adults, but anyone can benefit from them.
Conclusion
Ultimately, the best exercise is the one that aligns with your goals, keeps you motivated, and is sustainable in the long term. A combination of cardiovascular exercise, strength training, flexibility exercises, and activities that promote balance and coordination can create a well-rounded fitness routine that maximizes health benefits. Whether you're aiming to lose weight, gain muscle, improve endurance, or simply feel better, there’s an exercise that can help you achieve your objectives.

How much exercise do I need?
The amount of exercise you should get depends on various factors, including your current fitness level, your specific goals, the types of exercises you plan to do, and whether you have any imbalances in areas like strength, flexibility, or balance.
As a general guideline, it’s recommended to get 150 minutes of moderate-intensity aerobic activity (or 75 minutes of vigorous exercise) each week as a minimum. As you improve your fitness, you may want to exceed this amount to maximize your benefits. You can split the 150 minutes in a way that works best for your schedule, such as 30-minute sessions five times per week, or even two 15-minute sessions in a single day.
For strength training, aim to target all your major muscle groups two to three times per week, ensuring you allow at least 48 hours of rest between sessions to support muscle recovery. If you’re doing total-body workouts, two sessions per week should suffice. If you prefer splitting your workouts to focus on specific muscle groups (like a "leg day"), you may need to train more frequently, but still allow 48 hours of recovery before working the same muscle group again.
If you’re experiencing issues with balance, such as unsteadiness, dizziness, or vertigo, it’s a good idea to consult with a healthcare provider for personalized recommendations on balance exercises. Aim for three half-hour balance-focused sessions each week, along with at least two 30-minute walks.
When it comes to stretching, it’s best to warm up for a few minutes first, or stretch after your workout is complete. Stretching should be done slowly and steadily, holding each stretch for 15-30 seconds before releasing and repeating.
As for how much exercise is too much, some muscle soreness is normal, especially when starting a new routine or increasing intensity. However, if your body isn't recovering between sessions, you might be overtraining. This is especially true for seniors, who typically need more recovery time than younger individuals. With the exception of some "welcome" soreness, a good exercise program should leave you feeling energized. If it doesn’t, you're likely overdoing it. This doesn’t mean you should stop working out, but rather reduce the intensity or frequency until you find a balance that allows you to work hard but recover enough to enjoy your next session.
What are the benefits of exercise?
A well-designed exercise program can bring countless benefits to both your body and mind.
The positive impact of exercise on mental health is well-established. For instance, one significant study found that sedentary individuals are 44% more likely to experience depression. Another study revealed that people with mild to moderate depression who exercised for just 90 minutes a week experienced results comparable to those achieved with antidepressants. The key factor seems to be the release of brain chemicals like serotonin and dopamine, which help improve mood and reduce stress.
While exercise is widely recognized for its cardiovascular benefits, it also plays a role in lowering blood pressure. When you engage in aerobic exercise, your blood pressure temporarily rises as your circulatory system works harder. However, after your workout, your blood pressure typically drops to a level lower than it was before you began, helping to improve overall cardiovascular health over time.
Exercise is often linked to weight loss, and while diet is certainly important, exercise plays a key role in burning calories and reducing fat. Cardio exercises, such as running, cycling, or swimming, are particularly effective at burning calories. However, strength training is equally important, as it helps optimize your body’s muscle-to-fat ratio and strengthens bones, making it a vital part of a weight-loss program.
There is no one-size-fits-all "best" exercise for weight loss. The most effective exercise for shedding pounds is the one you’ll stick with. Whether it’s cardio or strength training, the key is consistency. Find an activity that raises your heart rate, keeps you engaged, and is enjoyable enough to stay motivated—this is the exercise that will help you achieve your weight loss goals.
Psychological benefits of exercise for older adults:
Exercise offers numerous psychological benefits for older adults. It helps reduce symptoms of depression and anxiety by releasing endorphins, which improve mood and promote a sense of well-being. Regular physical activity can also boost cognitive function, enhancing memory and focus, and may reduce the risk of cognitive decline. Exercise promotes better sleep, which is crucial for mental health. Additionally, staying active fosters a sense of accomplishment and self-esteem, leading to improved social engagement and overall quality of life.
What exercises are best for heart health?
The most effective exercise program combines both aerobic and strength training to strengthen your entire body, boost endurance, and promote long-term health. However, if your primary focus is improving cardiovascular health, you should prioritize cardiovascular exercises that challenge your heart and lungs, increasing oxygen flow to your cells. While strength training does offer cardiovascular benefits, aerobic exercise is particularly effective at reducing blood pressure, maintaining the health of your arteries' inner walls, breaking down blood clots through enzyme release, and even fostering the growth of new arteries that supply blood to the heart.
Consistent aerobic exercise also plays a key role in reducing the risk of type 2 diabetes. Although diabetes is often not considered a heart issue, lowering your risk of diabetes also helps lower your risk of heart disease. High blood sugar can damage blood vessels and nerves that control heart function. Exercise encourages your body’s cells to absorb glucose (sugar) from the blood, improving insulin sensitivity, which is crucial for regulating glucose metabolism. The benefits of exercise extend beyond the workout itself, as your cells remain more sensitive to insulin even after you've finished exercising. Since obesity is a major risk factor for diabetes, activities that help reduce body fat, particularly around the waist, can significantly lower your risk of developing the condition.
What can I do where my exercise ability is limited?
Everyone can and should do some form of exercise, even if they face severe limitations. Experts have designed specific exercises for seniors that are low-impact, safe, and able to be done even from a sitting position if necessary.
If you're concerned about fall risk, balance exercises for seniors can be done holding onto a chair or door frame. For example, standing behind a chair, you can hold its back and lift one leg to about the height of the middle of the calf of the other leg while tightening your abdominal muscles. As you progress, you might try holding the chair with just one hand, and eventually letting go of the chair.
Even core-strengthening exercises for seniors can be adapted to those with limited abilities. For example, a standard plank is done by holding yourself parallel to the floor with only your forearms and toes touching the mat. An easier version allows you to also place your knees on the mat. But a still easier method is to do the plank while standing and leaning forward. You put your elbows and forearms on a desk, table, or wall while resting on the balls of your feet and keeping your back straight.
There are a variety of stretching exercises for seniors to suit people of different abilities. If holding poses on your hands and knees is out of the question, you could try a full-body stretch in which you lie on your back, straighten your legs, and extend your hands along the floor past your head. Some stretches can be done while seated, such as overhead stretches and neck rotations.
In fact, other types of exercise also can be done from a seated position. Other chair exercises for seniors include bicep curls (with dumbbells or elastic bands), overhead dumbbell presses, shoulder blade squeezes, calf raises, sit-to-stands (chair squats), and knee extensions.
