I’m a 31 year old male, 5′10 and weigh almost 200 pounds. I am trying to lose weight and have started doing around 30 minutes a day of running in place along with some other cardio exercises. Is it going to put too much strain on my heart if I start doing it twice a day?

No its great as long as you are in good health! You might want to add some variety to your workouts by adding strength training.
