Thank you. That really helps. That information confirmed a lot of what I have already, but I actually didn't know that isometrics were used to TREAT hypertension. That's very interesting.

On Blood Pressure by: Paul from Isometric-Training.com
Hi Jacob,
You mentioned the risks associated with high blood pressure - it may surprise you that the risks are far higher with conventional weight lifting. (I'm discussing this in more detail and the compression damage caused by conventional lifting in my upcoming ebook on Arm Development). Isometrics performed while holding one's breath certainly is dangerous and something I would never advocate, furthermore it's not effective. I discuss proper isometric breathing techniques in my Ebook.
In the March 13th Issue of the Wall Street Journal 2003 appeared an article "Fears Mount Over Dangers of Pumping Iron" - http://www.pulitzer.org/year/2004/explanatory-reporting/works/story2.html - discusses the evidence that conventional weight training produces dangerous blood pressure levels.
Strangely the most common treatment of Hypertension (High Blood Pressure) was Isometric Contractions with breathing techniques. This method was popularised by Rene Callet M.D. Clinical Professor at the University of South Carolina School of Medicine and Bronio Kiveloff M.D. Associate Chief of Rehabilitation Medicine at New York Infirmary Beekman Downtown Hospital and actually significantly lowers blood pressure and improves cardiovascular strength, health and performance.
Furthermore studies were also published in the Journal of the Royal Society for the Promotion of Health about isometrics and the treatment of diabetes (due to fast increases in musculature over any other training method without compromised health and safety).
As for rupturing blood vessels, yep that's quite true. But then again, so does blinking...and also every time your fingers hits a key your rupture a load of capillaries blood vessels..(incidentally you might not be aware but as well as my personal training company I also run a full time Private Medical Practice specialising in Acupuncture and TCM, though I am also a qualified Western Clinical Medic).
