Many naysayers will tell you that exercise will aggravate a blood pressure problem, as your blood pressure is connected to your heart’s activity. And, yes, that would be true, with the exception that regular exercise improves the muscle strength of your heart, and in so doing so, helps your blood pressure to be regulated. A strong heart will be able to pump more blood with less effort. This equates to your arteries having to work less, and essentially lowering your blood pressure.
Your blood pressure will rise during any exercises, but it will soon relax to a normal activity after your have cooled down. The best type of exercise to improve your blood pressure would be any type essentially, but it is idealistic to choose exercise that is aerobic. 
And by aerobic, we mean the type that raises your heart rate above normal day-to-day beats. Having said that, any exercise, no matter how little, will bring on positive results to your body and lifestyle, as a whole.
You want to be maintaining blood pressure a little lower than or equal to 120/80 mm HG. Weight control is paramount to keeping your blood pressure down. The more weight you hold, the better chance of your body taking strain and your blood pressure rising. In particular, when you start to age, your body, overall, will take a lot more effort to function, and the blood pressure is generally one of the first areas to show the age.
While we suggest including one or a few of these aerobic exercise regimes into your daily lifestyle, we do also recommend that you check in with your doctor first.
Regular exercise is vital to a holistic healthy lifestyle, but especially if you have blood pressure issues. You should have a health check completed by a qualified medical practitioner before starting out on this exercise journey. And, you may want to start off slow, progressively increasing the pace and effort as you feel fitter and more able to, always paying attention to how you feel, and how your heart is reacting to the training. 
The 5 Best Exercises to improve your blood pressure
It is the easiest form of exercise, in terms of slipping on a pair of walking appropriate shoes, gear, and getting going. And if done right, you can drastically improve your quality of life and sort out any blood pressure issues.
Walking has many other benefits that all aid how your heart manages. The calories burnt whilst walking will help you bring the weight down, and having a 30 minute walk every day, also helps with increasing brain power. It is said that dementia can be held off longer if you just ensure you take at least a 6 mile walk a day, that amongst other brain fuelling activities. 
Running takes the exercise up a beat, as it does require more effort and is harder on the muscles and bones, especially the joints.
Again, like with walking, you will burn calories and keep a clear mind for longer, but a regular running routine extends further, with helping you boost confidence, lower blood pressure (this by opening up the arteries and veins for better blood flow), and in turn reducing stress. 
Aerobic classes at a gym or outdoors adds a new dimension to aerobic style exercise. You get the benefit of raising your heart rate, but also the diversity and anti-boredom aspect, that walking and running can induce.
Other Outdoor Aerobic Sports
Other aerobic sports, generally enjoyed outdoors, can include cycling, swimming, basketball, and tennis.
Swimming, specifically, is a great beginner style sport or training. It is gentle on the body, with no jarring motion or the hitting of foot to tar, and you can really start out as slow as you want, even walking in the water till you are ready to progress further.
Ball sports, such as tennis, basketball, cricket, football, and many others, are great for the aerobic effort, but also the effort it places on the brain. You have to move, energizing the heart, pumping the blood faster and creating a path for good blood pressure; and in addition, you need to exercise the brain more, what with the ball needing to be kept in eye distance all the time.
Cross-over type sports that involve a ball and perhaps also a “utensil” such as a racquet or bat, require that you apply your gross motor skills into the equation, always good for getting the brain cells working. 
This one may not get your juices going at first glance, but if the cleaning must be done, then you may as well put it down to part of your exercise regime. Vacuuming, dusting, polishing, and scrubbing floors, all require some effort and muscle activity.
You will be surprised at how much your heart rate will increase when indulging in the art of house chores. And, it really is an art, because, while you may be making an effort, not everyone can clean expertly.
But, nevertheless, grab that cloth, pick up the vacuum, and get moving, and if you find your heart rate isn’t picking up too much, try jogging on the spot to just aid the benefit you are giving to your heart strengthening.
