Frequently Asked Questions

Cardio exercise strengthens the heart and lungs, improves circulation, boosts endurance, and helps regulate blood pressure. It also supports weight management, enhances mood, and reduces the risk of chronic diseases like heart disease, diabetes, and stroke. 

The best cardio workouts depend on your goals and fitness level. Popular options include running, cycling, swimming, rowing, jump rope, stair climbing, and high-intensity interval training (HIIT). Low-impact choices like walking or using an elliptical are great for joint health. 

The American Heart Association recommends at least 150 minutes of moderate-intensity cardio or 75 minutes of vigorous-intensity cardio per week. This can be spread over 3-5 days depending on intensity and fitness goals.

HIIT burns more calories in less time, improves cardiovascular fitness, and boosts metabolism post-workout. However, steady-state cardio (like jogging or cycling at a moderate pace) is better for endurance and can be easier on the joints. A mix of both is ideal. 

Both play a role! Cardio burns more calories during a workout, while strength training builds muscle, which increases your resting metabolism. A combination of both is the most effective approach for long-term fat loss and overall fitness. Cardio primarily improves endurance and burns calories, but certain types, like rowing, stair climbing, and sprinting, can help strengthen muscles. However, for significant muscle growth, strength training is essential.
