The number one reason why diets fail is because without support people burn out quickly and the lofty plans to get to the gym every day and cut back the calories fall by the way side.
Sticking to a strict workout plan and diet plan is hard, which is why having a partner in crime can be the best decision you ever made. That way when one of you gets weak the other one is there to whip you back in shape and get you back to the gym or your diet plan and vice versa.
One of the best ways to stick to a diet and exercise plan is by finding an exercise buddy that wants to lose weight just as much as you do. After all, while you may be able to talk yourself out of going to the gym, if you know that someone else is already on their way to meet you it will be harder to make the decision to sit a day out. When people have someone else to lean on they also have someone else they are responsible to making it harder to quit out early.
Therefore, if you have failed in the past at any true exercise routine this time around you need to grab a girlfriend and make plans to pump some iron. Whether you choose someone who is already in shape or someone who wants to shed a few pounds, the very fact that you have someone watching your every move will inspire you to work that much harder. The more people who want to help you lose weight the better the chance that this time your plans are going to stick, and the higher the chance that you will get off the couch every time.
