What is the best way to maintain a healthy heart and prevent thickening of the heart muscle? I feel like cardio would help keep your blood pressure down, but I know that runners typically have larger than average sized hearts, so I'm not sure if cardio is the best strategy to keep your heart from becoming large/unhealthy. Any good OTC supplements as well?
Just make sure your fats come from mono/poly sources, i eat eggwhites with peanut butter and mix extra virgin olive oil into non fat yogurt, supplement the regular regiment of cod liver oil, coq10 and nessecary multivits etc.
All luck of the draw eitherway, a relative of mine has been competing and using since his teens and is now in his 50's and still competing, orals, oils, slin, gh, every type of fat burner bar dnp, got his recent check up and he had one liver enzyme slightly higher than normal coming off a show where he was running tren,mast,prop every day 10iu hgh every day and at least 30 units of insulin a day minimum.
Other end of the spectrum a friend of mine just got diagnosed with high cholesterol and has been prescribed statins before 25, his father had a quad bypass in his early 40's and his grandfather died of a heart attack around the same age.
Avoid rec drugs since they compound problems for zero gain but there's nothing anyone can say to me at this point to deter me from steroids, always take precautions by all means but seriously the health concerns are way fucking over blown, genetics are the biggest factor by far and some of us just arent destined for a long life.
Also heart hypertrophy is only detrimental if its actively causing reduced function which you can check with an echocardiogram, everyone who lifts seriously has this to some degree and it's not life threatening in its self, the worst factor contributing to heart failiure is just being too fucking heavy and is a common symptom of obesity.
Long story short, don't worry so much, give your body a rest, be mindful of your diet, don't expect to maintain 300lbs into your 50's unless you want to wind up in a big coffin.
