I've worked out between 4 and 6 times a week for as long as I can remember. Some times the intensity dies out but I keep up with it. I was still carrying around and extra 10-12 lbs from not eating right and drinking too much.
My wife booked a vacation trip to Playa del Carmen for 1/1/12 to 1/8/12. I cranked up the intensity on the workouts, didn't skip my cardio workouts, and ate clean over since the end of October. I lost 12 lbs before we left. We had a great time and we worked out almost every morning before going to the beach/pool each day. We ate and a drank what we wanted and my wife was shocked when I got on the scale at the fitness center on the 5th day. I was only up 1lb.
I've kept it off and plan to drop another 5 to 7 lbs. before the end of March. It's all about shutting the pie hole. Don't each anything with refined sugar and stay away from high glycemic carbs.
This is our last night in Playa del Carmen well on our way to be over-served with some friends. I'm all the way on the right and my wife is all the way on the left.
