I'm keen to know more on when I can do specific exercises after neck/chin liposuction?

It is always best to be at your ideal weight for this procedure but to be honest this fat is persistent in most people even with weight loss which is why we do it.
As far as exercise goes, it is up to your surgeon. I allow people to slowly start back up with cardio at 2 weeks. Then advance as their body allows them without pain and swelling. Hope this helps.Best of luck,DrC   

A quicker #recovery for a patient may be two to three weeks without any strenuous activity. This includes the short period of suggested rest of 12-24 hours soon following the procedure. #Exercise and activity are contingent on how the patient feels. Mild activity is not likely to hinder recovery or healing or create problems with recovery.  However, it is recommended to acquire your doctor's permission to do so. Once you begin exercising again, start gently and let your body tell you what it can tolerate. Don’t rush!  If you have concerns about your healing, or pain that you question to be unusual, it is important to call your plastic surgeon to discuss these further asked to be examined. 

 Hi, I have performed many facial shaping procedures using dermal fillers, facial implants (cheek, chin), liposuction and/or facelifts for over 30 years.  It's best to follow your doctor's post op instructions.  We typically use 1 month as the time limit to refrain from all "strenuous" physical activity. The type doesn't matter, it's the increase in heart rate and resulting increase in blood flow to the surgical area...in this case your neck that can increase bruising and swelling in that area.  That's the basis behind limiting activity and blood thinners during the post op period.Hope this helps.
