Intense Exercise

Intense exercise uses everything. Unlike going to the gym for 2 hours to lift weights or jogging for an hour, an intense work out that lasts let's say twenty minutes will work everything. If the exercise is intense enough, you will be working your strength, balance, muscle endurance, mild cardio, moderate cardio, intense cardio, coordination, agility, speed, quickness, flexibility, recovery, lung capacity, nervous system, etc. Because it will be so hard on your body, every system has to coordinate to complete the task. As opposed to mild exercise that takes a long time like jogging or weight lifting where your body can rest a lot, use one system or one muscle at a time and take a break.

Believe it or not, not only will you save time, get better results, but you will get less injured. Most modern injuries are due to pattern overload, over use, or chronic repetitive trauma. Whereas with intense work outs, you don't need to do it every day or other day. Even once a week will tax your system to create beneficial change.
