My pectoral and what Im assuming are my latissimus dorsi muscles are pretty pronounced, and there isnt alot of tissue in between. When I lift my arm, there is a pit. Most razors dont fit width wise, and the heads dont pivot from side to side. The hardest part is getting under the pect. It takes a lot of careful maneuvering to get the whole pit shaved. I've been looking online, but Im not having success on google. Does anyone else have this issue, and have you found a solution?
