Exercise - Longer May Not Be Better

How much physical exercise do you really need? You definitely need some every day. How much time do you need to devote to physical exercise every day? Opinions differ. According to Dr. Borkin, studies have shown that physical exercise beyond 42.5 minutes can have a negative response on cortisol levels (cortisol is one of the stress hormones--you need some of it lp you manage stressors effectively; too much cortisol can cause all manner of havoc in the brain and body). Knowing this, Borkin recommends exercise for only 40 minutes at a time. If you want to do more, wait at least 20 minutes before restarting exercise. (Borkin, Michael, PhD. Sabre Sciences, IncTM.
