Will building muscle after a BBL ruin my results?

For most patients strenuous activity can be resumed 6 weeks post op.  Squats and lunges after BBL will increase muscle bulk and definition, which is probably a good thing if you are looking to achieve a more projected, lifted buttock.  However, just make sure that the body fat percentage is held in check or you will lose some of the fat. 

Hello, thank you for the question.
I personally dont recommend to excercise till you're fully recovered. After that, exercising will improve the look of your buttocks. So, you don't have to worry about it. Best of lucks.

Dear gogina,
building your gluts is a great way to enhance your buttock region and I recommend to all of my BBL patients. It not only ads volume to the buttocks but lifts the buttocks in a more anatomic position.  But every plastic surgeon has his own postoperative protocol which he recommends to his patients. I would suggest you to discuss this with your plastic surgeon.
