Question: Is a heart rate of 150–160 bpm during cardio exercise normal for a 40-year-old male?

I'm a 40-year-old male, around 240 lbs, and recently started doing regular cardio (usually 30 minutes, 3 times a week). During exercise, my heart rate usually hits between 150 to 160 beats per minute. My resting heart rate is normal, and I feel okay during workouts, but I'm just not sure if this heart rate range is safe or too high for my age and weight.

Should I be concerned? Is this within a healthy range for fat loss and heart health, or am I overdoing it? I’d appreciate insights from fitness folks, health-conscious users, or anyone who’s been through similar changes. Thanks!
