Thanks to a heads up from a client of mine I will retract the statement from the post of Aug. 27 where I recommended not exercising right before bed.
One of the few studies on the topic (http://www.ncbi.nlm.nih.gov/pubmed/9628115) actually found test subjects who exercised late at night slept better and felt more rested the next day. In addition, a leading researcher on sleep disorders, Dr. Shawn D. Youngstedt at the University of South Carolina, believes that exercise before bed can actually promote sleep.
So you can no longer use “it is too close to bedtime to exercise” for an excuse. Every individual will vary in response to exercise timing, find out what works best for you and your schedule.
