Much of this will depend on your current fitness level. If you are just beginning exercise then each session may be a challenge. If you are fairly active then you may be able to complete up to 3 hard workouts per week. You must first figure out your fitness level and decide from there. A good suggestion would be to complete 1 to 3 hard workouts per week.

As a general rule, most fitness experts say don't work out hard more than three times a week. Of course, what is "hard" is highly individual and refers to whatever level of effort elevates your heart rate, brings on a slight sweat, and deepens your breathing. If you're prone to injuries, three "hard" workouts a week may be excessive, at least for the first several weeks, until your body becomes accustomed to the effort; there's good evidence that the risk of injury increases as you work out hard more than three times a week. If you're cross-training, however, you'll have more latitude in this regard if you alternate activities that work the upper and lower body.
