The thinking for some was and probably still is in some cases, that the body fairs best around about 2-5 PM, because that is when the body should be most alert, for people using commonplace waking and sleeping times, so exercising between these times should theoretically have a more optimal performance yield.
However, it's when you can find the time, not when it might be physiologically best to do it. It's no use having that theoretical performance peak, if you cannot take advantage of it, due to commitments during that 3 hour time period, so it's a case of fit it into your life the best way you think you can and try not to worry about it.
