How much cardio does my heart actually need?

150 minutes per week of moderate movement (like brisk walking) is the AHA recommendation. Splitting it into 20–30 minute daily sessions works well.

Are high-intensity workouts safe for heart health?

For most healthy adults, yes — but build a base of Zone 2 walking or cycling for 6–8 weeks first, and clear it with your doctor if you have a cardiac history.

Can walking really lower blood pressure?

Yes. Consistent daily walking of 30+ minutes has been shown to reduce systolic blood pressure by 4–9 mmHg over a few months.
