However, I have researched the issue at length and found evidence that at max exercise in trained men,
SBP of 210 to 230 is the norm. To answer the question
for myself, I enrolled in a cardiac rehab class and had them check my bp at varying levels of exertion. The significant finding was that bp tended to shoot up rather quickly as I started exercising, but if I did an extended warmup at heart rate of 110 or less, it reached significantly lower levels at the greater exertion.
