@dew88 just a comment, it is known that while exerting your BP spikes significantly especially if your holding your breath, and starts coming down immediately after the exercise/rep from its peak so if you measured 170/79 right after, the peak was actually higher.

I asked Dr Prakash once about ways to measure BP while exercising, and he told me there is absolutely no way for someone to do that, the current methods are just too sensitive to movement.
