Will 20 Minutes make a difference?

Oh it's almost that time, back to school time and for the months of August and September the "time" to workout is even shorter. Lots of people say 30 minutes is plenty of time and some people say on its  not. Well what if I said a targeted 20 minutes can still make a difference. Now, if you choose these INTENSE 20 minutes it must be just that! You should be out of breath, sweating, and feel the burn if it's to work.  You can't take those 1-2 minute breaks at all! I mean it's on,y 20 minutes and you need to do it 5-6 dats a week.  

So what does 20 minutes that work look like? Here's an example

Warm up
50 jumping jacks
50 high knees
50 butt kicks
50 vertical leaps
50 side to side lunges
50 step backs
--------1 minute break--------
