      It really depends on your training goals and your health status. If you have no known cardiovascular issues, the only limit is your ventilatory threshold (when it gets hard to breathe), and that is simply because exercise that exceeds that level is not sustainable for long. Otherwise, you can work out at any heart rate you want to. You’ll likely get more training benefits from doing at least some vigorous exercise, or some faster intervals during moderate workouts. Don’t work out harder than is a comfortable pace at which you can still talk until you have some baseline conditioning under your belt; even then, you don’t have to work out so hard that you can’t talk to get the benefits of training.
