Besides going to doctor and getting their OK, the most important part about learning how to start exercising again is "why." The "why" or the reason behind starting has to come from the person, not a family member, doctor or spouse.
After the "why" is determined, goal(s) would be the next step. Too often people look at simply "losing weight" or "getting back into shape" as the goal. This is not a goal but a vague hope. When a person establishes a S.M.A.R.T.E.R goal they are more likely to not only hit it, but exceed it. This applies to all areas of a person life, not just learning how to start exercising.
