Wubby, when you hit a plateau, up the ante in your workouts (keep hitting your peak everytime) tell your body we's gonna do things differently 'round 'ere
Let your body know it's under NEW MANAGEMENT, and its not business as usual.

So try changing up your workouts (hit new peaks), and try to change up your meals by trying this . Here's a suggestion that I read :
^^^^Have a month where you do (4 on, 2 off - 4 days of the week you eat the way you have prescribed for your diet and for 2 days, you eat a VERY HIGH PROTEIN LITTLE OR NO CARB diet.^^^^^
This is designed to trick your body into thinking something new is going on and adjust to the changes. ___I hope you find something that works.
