Cardio Exercise
(Great for Heart and Endurance)
Cardio exerciseβshort for cardiovascular exerciseβrefers to physical activity that raises your heart rate and keeps it elevated for a sustained period. It primarily strengthens the heart and lungs, improving overall cardiovascular health.
Key Benefits:
- Improves heart health and circulation
- Burns calories, aiding in weight loss or maintenance
- Boosts endurance and stamina
- Enhances mood by releasing endorphins
- Lowers risk of chronic diseases like heart disease, diabetes, and high blood pressure
Common Types:
- Running or jogging
- Walking briskly
- Cycling (indoor or outdoor)
- Swimming
- Jump rope
- Rowing
- Dancing
- HIIT (High-Intensity Interval Training)
Guidelines:
Health authorities recommend at least 150 minutes of moderate-intensity or 75 minutes of high-intensity cardio per week for general health.
Running and jogging are powerful forms of cardiovascular exercise that benefit both the body and mind. While jogging is typically done at a slower, more relaxed pace and running at a faster, more intense one, both activities improve heart health, boost lung capacity, and strengthen musclesβespecially in the legs and core. Regular practice helps burn calories, promote fat loss, and increase overall endurance. Beyond the physical benefits, running and jogging also support mental well-being by reducing stress, improving mood, and releasing feel-good hormones like endorphins. Whether you’re aiming to stay fit, lose weight, or clear your mind, running and jogging are simple, effective ways to enhance your health and energy.
