My exercise routine has changed slightly but it's working. I've discovered that I love exercising in the mornings. It keeps my energy up all day. The plan is simple:
Exercise Monday - Saturday with Sunday as a rest day.
Each day, do at least thirty minutes of cardio. Then, strength train all six days, alternating upper body and lower body. Monday I worked my upper body, today I worked my lower, tomorrow I will work upper, etc.
Finish all that off with ab training each of the days.
