Depends on what you want to achieve. "Intensity" is too broad a word. Very different workouts can all be intense. In general, unless you have already been exercising for quite a while, high intensity workouts tend to be unpleasant and thus quite frustrating. It is more important to be able to stick to an exercise at a moderate intensity than to dread your exercise sessions. Some ideas:
- If you want to run a marathon, you need to do endurance training, so being able to run for a long time is important. But don't try to accomplish too much too soon.
- There are fans of HIIT (high intensity interval training), but that is for people who are already in love with exercise.
- If you want to lose fat, do strength training starting with body weight exercises (there are many such exercises well explained in this site). Again, don't do it too intensely. When it becomes too easy, you graduate to free weights, but that requires some trainer to show you how to use them. Walking is also a great way to control the caloric deficiency, so you would want to do some walking too.
