Hope this isn't dumb. I'm not starting a cycle any time soon but it could very well be in my future later on down the road. I'm just wondering what the advantage is (if there is any) of pinning tris/bis/trap/calves. Friends and acquaintances of mine usually just stick to delts/quads/ and glutes. So does it affect the body different or do people just pin in those random other areas (bi/tris etc) just to switch it up?
