yes! do tabata training! here is a link to get you started.. http://tabatatraining.org/
tabata workouts are short (usually 4 mins..) high intensity interval sets that you repeat three times.. it’s short but to the point, and it’s a GREAT way to get in to shape.. it’s really hard though, because it’s really high intensity, but you of course can build up your ability and endurance through time! :) Also, www.blogilates.com has some good short workouts you can follow. :) good luck!
