I've been hypertensive for more than 10 years. And, this is one of the reasons why I went into biking 6 years ago hoping to control my blood pressure.
On Facebook, I found a group called "Hypertensive Cycling Group Philippines". It's obviously for bikers with hypertension as well as those with other cardiovascular problems. A member is encouraged to share his health concerns, tips, experiences for the benefit of other members.
If you are a biker who has any cardiovascular problem, you may also join this group at www.facebook.com/groups/hypertensivebikeclub
See you there!
