Ziplining with Health issues
A. Most of the time if you have to ask the question, you already know the answer. Zip lining is an energetic and frequently strenuous activity which could easily place strain on a heart which is already compromised by disease or problems. You must frequently lift your own body weight and hold it for several seconds at the beginning and end of each run. You would be best to avoid this activity if you have heart problems of any kind.
You must also talk to your doctor about zip lining if you have certain conditions such as: Heart conditions, High blood pressure, Neck and/or back issues, Dizziness, Seizures, or Debilitating fear of heights
