Exercising will improve your overall health. Moving from a sedentary lifestyle in which you do very little activity to a lifestyle in which you engage in even just moderate activity will go a very long way in giving you some real health benefits such as lower blood pressure, increased muscle mass and a lower body fat percentage. Tweaking your exercise routine can help you even further. There are plenty of strength training routines you can choose, the two main ones being: 1) full body or 2) split routine.
