Being a fitness professional there are three main reasons I see why people fail to change their bodies
1. Not changing their nutritional lifestyle. Remember lifestyle changes can take time and for some it comes much faster than others, but always focus on your goal.
2. Not pushing and challenging themselves in their workouts. If you have been walking for years and not seeing the results you want then you must increase intensity levels!
3. Not believing you can change and not making a commitment to change.
So Jeremy what can I do?
Learn about nutrition, seek out those that can help including fitness professionals, nutrition professionals, and anybody else that can help. Make a commitment that you will stick with this new lifestyle but if you slip up then start again tomorrow. Learn how to set goals and do not let anyone stop you from these goals. Find those that support you and learn from them.
Yours in fitness
