Here's an example of some conditioning work you can do with little to no equipment that I demonstrated in my last video.  You don't always have to 30/45/60 minutes doing cardio.

Remember, be patient and go at your fitness level.  Do this routine 2-3 times per week, increase your time by 5-10 seconds each week.  Do other activites on the alternate days. Get out and play with your kids, go to the park, hang on the monkey bars, swing on the swing for 1 minute as hard as you can, race them to an object the park, make it a game. Let your body adapt.  If you are exercising for the first time or haven't done so in awhile, please consult your physican before you start.  Have fun!
