Do platysma muscles get worse (more prominent) from weight lifting?

The platysma muscle can become more prominent if during weight lifting, you are straining your neck.  This also applies to sit ups and any other repeated strenuous facial and neck exercises that cause the bands to contract.  We will, in fact, often inject Botox into the platysma muscle to relax it and give a sort of instant neck lift.  Patients often ask about facial exercises and keeping their facial muscles tight.  There are a few yoga exercises for the face which are fine, but unlike skeletal muscle on your body, I don't recommend strenuous exercise of your facial muscles as it can lead to more wrinkles with time.  Weight loss can also make the platysma more prominent.  Botox, Ultherapy, ThermiRF, Exilis Ultra can all help with bands.
