A lot of studies on obesity and your heart, but I cant find anything about BBing and your heart other than AAS use. My question, is a greater BMI not just obesity but just larger BMI a strain on your heart and its not necessarily the AAS use but being abnormally large that makes your heart struggle. I'm kinda thinking its akin to taking a small truck with a 4cylinder engine and putting that engine into a larger truck that should have a v8 engine and driving it as hard as you can requiring it to pull weight that it can barely handle?
