Someone I know gave me a copy of the workout plan he was given by his personal trainer. It involves 3 days at about 1 1/2 hours a day. Currently, I do this, but I spend about 1 hour of it doing cardio, then half an hour doing weights (only the main muscle groups). This new plan recommends 15-20 minutes of higher intensity cardio per day, and the rest of the time doing weights. Now I really know nothing about working out, but one thing I do know is that the more cardio you do, the more calories you burn. Since I first and foremost want to lose weight, should I be cutting down my cardio so significantly?
