I work about 40 to 45 hours a week at my office, sitting most of the time. My company allows me to adjust my time table and I can arrange my working hours as I like, as long as the job gets done.
I want to increase my productivity during working hours, so I analyzed my daily productivity curve. Morning is perfect for me, I achieve a lot from 9am until lunch break, which I usually take around 1pm. Afterwards I often feel drowsy and my motivation starts to lack, especially after eating too much. Sometimes this condition lasts for several hours, affecting my productivity more than I like.
The first two changes I want to make to improve this situation is sleeping more during the night and changing my diet to lighter meals for lunch. I am also considering hitting the gym after lunch (it is in the same building as my office) to get fresh energy. Now I need to find out, which kind of training will help me to regain my mental fitness for my work in the afternoon.
Which exercises would be good and how long should I work out? Including a quick shower I do not want to spend more than an hour, but I guess more wouldn't help my cause anyway. Should I start my workout right after I ate or is it better to wait a little? Or is this a bad idea all together and it wouldn't help me to achieve my goal?
