Maximizing my gym time
 

Hi y'all...need some expert ideas. (Here's a chance for you all to play personal trainer!)

I have approximately 45-50 minutes a day to work out in the gym. Based on the following things I have available to me, what should I be doing to maximize my time at the gym? (NOTE: I want to burn fat as much as possible, since I have so much to lose!)

circuit w/10 machines and 10 recovery stations
treadmill
elliptical
Gazelle
stability balls
punching bag/kickboxing bag
hula hoops
hand weights
resistence bands
steps
medicine balls of all sizes
jump rope (not quite ready for this one yet!)

I like doing circuits where during the rest part I do to minutes or high intensity cardio.

I hadn't tried that....thanks!
