I am new to CNS. I am just finishing my first week of re-orientation. I have a question about exercise while following the CNS protocol. I typically weight train 3 days a week and do HIIT (high intensity interval training) 3 times a week. In the book, Kiefer says not to do high intensity cardio. My HIIT sessions are usually 25 min during which I do 5 sprints each 45 – 60 seconds (85-95% max heart rate) in duration followed by 3-4 minutes of rest. Is it ok to continue this exercise? Also, during my weight training sessions (about 1 hour long) I wear a heart monitor and my heart rate is in the high intensity (80 to 90%) range about half of the time. Is it ok to continue this? I look forward to your feedback.
Thank you
