Best exercise regimen to lower Blood pressure

Cardio? Weights? What ratio mix?

Best exercise regimen fits the individual.  It is enjoyable and sustainable in the long term.  Otherwise quiting early yields temporary health benefits.  Probably low intensity in longer time period for most people.    For example, senior citizens may prefer walking or sight seeing in a shopping mall when weather is bad.

Medium cardio would be my choice.  Weights aren't going to do much. When I ride bike, I have a few hills where I try and push the tempo a bit and then recover while I'm still in "medium exertion" mode.
