Working Out on the Homefront
Some detractors may say the gym is better at keeping you motivated because other people are there. This doesn't have to be the case. You can turn on your favorite kind of music and have fun while you train. You will stay motivated knowing you don't have to waste time waiting for a particular piece of equipment to free up. It also helps to know you don't have to spend time traveling to and from the gym.
Safety concerns may cause some people to prefer a gym workout, because there is always someone there to aid you. But if you are careful at home, your chances of injury are slim. If you do need a spotter, just do those exercises when another family member is there to help you. The use of multi-exercise machines eliminates the need for spotters.
If you want to workout at home, you can very successfully do so. Go for it, and make your body the healthy machine it was meant to be.
