Easy work out for after my jog

Options
Im looking for a quick and easy routine for after I get done with my mile jog I do before I head to work. Right now ive been doing 3 sets of push ups and sit ups (about 5 each set) I'm usually in a time crunch in the morning because i usually work at 8 am and I am thinking about adding another half mile to my jog which now only takes me 15 minutes so im looking to fill in about another 20 minutes tops so I can still get up at a decent time get this done and then get showered and ready for work

Thanks again everyone has been extreamly helpful so far
