So I have no idea where to start. Im 5 foot 5 inches and 181 lbs, so im considered obese. i have two small children, work full time, and im a part time college student so my schedule is very full. nonetheless, i need to lose weight. also, im in the process of quitting smoking cigarettes, so i hope to be able to breathe through a workout soon. i started walking with a friend but i dont feel like its enough to really get the pounds off so i need help! any suggestions?
