Thank you for your question and your picture. In the picture, the wound looks healed already. The healing process of this surgery is greatly dependent on the following factors and can be highly variable:
1) Surgeon factors: the technique of surgery, the after surgery care.
2) Patient factors: whether the patient has some conditions that might affect wound healing.
3) Wound factors: the size and the location.
Every single wound is different, the best person to ask should really be the surgeon.
You should check with your surgeon if if is ok for you to start exercising when you go for your follow-up check ups.
