So I have one person telling me I need cardio in order to put on muscle and healthy fat and I have another person saying cardio will only make you skinner.I know cardio is essential to toning but I do not wish to become skinner in fact I would like to put on 10 healthy pounds.I want my body to be full.I'm tall so I look extra skinny. This week I only worked out 3 days this week & next I have to workout every day for an hour. This workout consists of bicycling exercise,squats,lunges,treadmil workouts, using the stepper along with a workout video,and using an exercise ball along with a video,and lifting weight. I recently started to use ankle weights and arm trimmers.Next week I know will be super hard but I'm up for it. I'm still not sure about the actual affects of cardio on my trying to gain weight,so I guess I better just talk to a professional and tell them exactly what my goals are. Trying to get rid of stomach fat and tone loose skin while trying to gain weight/muscle is the hardest.
