Although there are many sites that claim that they will show you weight training exercises online, in reality this is not the way to go.
If you want to start a weight training exercise program, you really need to be working with someone else. There are many options available. You can go to the gym, use free weights at home with a buddy, or get one of those machines, but if you do not do your weight training exercise with proper safety precautions, it is quite possible for you to get seriously injured.
I recommend doing your weight training exercise at the gym. There are several good reasons for this, and I will go ahead and tell you some of the very best ones. First of all, you can get a spot at the gym. Of all of the weight training exercise injuries, most of them could have been avoided with a proper spotter. This is especially true with free weights which can injure or even kill you if you are forced to drop them based on muscle fatigue. This is the most important reason to go to the gym, but it is really far from the only one. The fact is that it is easier to psyche yourself up for your weight training exercise when you do go to the gym. With all of those people around you are dedicating their time to getting in shape, there is just no way you will feel like slacking off in your weight training program while you are at the gym. Many gyms even have personal trainers available, who will help you to meet your personal best, by working you harder than you will yourself, and helping to chart your goals. They can even suggest which weight training exercises you should use and how many, to strengthen the muscle groups which interest you.
Before you start doing weight training exercise, however, you should do some cardiovascular stuff. While you can get by quite well without weight training exercise, cardio is absolutely essential to your health. You will live longer, be healthier, and happier, and even have more energy if you do some aerobic activities every day to keep you active. We do not stay young forever, but those of us who get adequate aerobic exercises do stay young for longer than those who do not. Once you start doing that, then you can add your weight training exercise program.
