Despite these genetic findings, targeted genetic therapy seems to have little impact on hypertension. In the general population, not only does it appear that individual and joint genetic mutations have very small effects on BP levels, but it has not been shown that any of these genetic abnormalities are responsible for any applicable percentage of cases of hypertension in the general population. 
You can take additional magnesium if you do not think you’re getting enough in the diet. Dr. Weil recommends magnesium citrate, chelate, or glycinate. Avoid magnesium oxide, which can be irritating, and take half the amount of magnesium as the calcium you take in supplemental form. If you do not take any supplemental calcium, watch out for taking large amounts of magnesium, which can cause diarrhea.
The United Kingdom Prospective Diabetes Study (UKPDS) was a clinical study conducted by Z that was published in The Lancet in 1998. Around 3,800 people with type 2 diabetes were followed for an average of ten years, and were treated with tight glucose control or the standard of care, and again the treatment arm had far better outcomes. This confirmed the importance of tight glucose control, as well as blood pressure control, for people with this condition.
Development of metabolic syndrome depends on distribution as well as amount of fat. Excess fat in the abdomen (called apple shape), particularly when it results in a high waist-to-hip ratio (reflecting a relatively low muscle-to-fat mass ratio), increases risk. The syndrome is less common among people who have excess subcutaneous fat around the hips (called pear shape) and a low waist-to-hip ratio (reflecting a higher muscle-to-fat mass ratio). https://www.healthshare.com.au/storage/avatars/patricia-durning.jpg.60x60_q85_box-0,0,100,100.jpg
Taking this a step further, I'd note that there are exercises that might not be self-limiting initially, but reach that point eventually. For example, with a beginner, a suspension trainer inverted row is not self-limiting at all; there are several important technique elements that a lifter needs to master because doing the exercise under conditions of fatigue.
The AHA/ASA recommends a diet that is low in sodium, is high in potassium, and promotes the consumption of fruits, vegetables, and low-fat dairy products for reducing BP and lowering the risk of stroke. Other recommendations include increasing physical activity (30 minutes or more of moderate intensity activity on a daily basis) and losing weight (for overweight and obese persons).
