Will aggressive weight lifting over time accelerate the undoing of my corset platysmaplasty?

Remember, remember, the truth of one's September:1. Aging will continue, whether you weight lift or not.2. Some degree of regression of repositioned tissue is invariable in everyone. If you lift weights, you will blame the loosening on the lifting of weights! If you don't lift weights, the degree of loosening you see will be apparent for what it is: natural relaxation of repositioned tissues. Not a return to the preoperative state but a mild to moderate regression!3. There is no substitute for following your surgeon's advice as you trusted him with your surgery. He will have experience of this type of surgery and result and will have had to answer this question before bearing in mind your age, degree of invasiveness of the surgery, etc.4. The best way to maintain the result is to not gain weight!!!Good question: gives one a chance to think about healing and regression.Enjoy your obviously excellent result.Prof. Bhupendra C. K. Patel MD, FRCS

I am happy that you are thrilled with your result.  Although weight lifting at 6 weeks shouldn't have any negative effects on the outcome of your procedure, I strongly recommend that you defer to the instructions of your Surgeon.

Platysmal banding, protrusion, and skin laxity can be more noticeable in those with a low body weight, but if your weight remains relatively stable post-op then it's unlikely that your results would be affected by resuming exercise. Once you do start lifting weights again, use caution and ease into it. To avoid an increase in blood pressure, be sure to follow regular breathing patterns during exercise.
