Help me. I've plateaued :(?

You need to change your routine. Change the time fo day you go to the gym, and change the machines you are using. Use the elyptical, treadmill, and bike. Use the various weight machines and do a high amount of reps with a relatively low amount of weight. Alternate between cardio, weights, and ab workouts. Modify your diet even further to eliminate excess fat, while ensuring you are getting the calories and nutrition you need.
