Exercise to Reduce Cancer Risk

Recently, my boyfriend has taken up running as a cardiovascular activity to help him get into better shape. Already an experienced personal trainer who is familiar with weight training, he began to take a more active interest in pursuing cardiovascular exercise as a way to help him improve his overall health.
Exercise is good for you. It helps to keep your blood circulating smoothly and promotes new cell growth in your muscle tissue, which is great for burning more calories later. In turn, when you exercise, you are typically more motivated to make wiser food choices and you are also prone to just generally feeling better overall. The change for some people who have never exercise but who have recently started to exercise can be quite dramatic. For example, there was one story of a woman in the news who lost over two hundred pounds simply by starting a fitness routine that involved walking once a day for thirty minutes. After she made it through her first thirty minute walk and realized that it didn't kill her, this made her even more motivated for her second walk the next day. One thing led to another, and before she knew it, she was jogging in between her walks. Today, she feels better than ever.
There are some people who never fully benefit from all that exercise has to offer though. These are the people who have the gym membership because they think that by paying money for a gym membership, it will motivate them to use the gym more frequently, thus increasing the number of times that they work out. However, nothing could be further from the truth. In fact, most people who own gym memberships: a) never go to the gym except, of course, when the holidays roll around and/or b) go to the gym but only so that they can eat more afterwards. The second type of gym goer is the most common. This is the person that we see at the gym consistently, over and over again. However, for as often as we see this person at the gym, they never seem to be making any headway in terms of muscle development or weight loss. Part of this is due to the fact that they simply do not know how to utilize the weight machines/equipment the right way. But part of it is also due to the fact that many people are made to feel guilty to do the gym routine. They go to the gym thinking that if they run thirty minutes or more on the treadmill and the treadmill tells them that they've burned "X" amount of calories, that this will then mean that they have a calorie deficit which can then be filled with the junk food of their choice.
As studies (and real life) have proven, exercise is good for you, but you have to make sure that you are doing it effectively. You only get out of life what you put into it, and the same thing can be said for your body in terms of exercise and diet.
