HIIT of some sort. I get shinsplints so I don't have much luck w/ the sprints, but you can do intervals on any eqpt. I tend to mix up all 4 of those and also spread steady-state and HIIT across them as well.
eliptical hit by far. i burn over 1100 calories an hour, usually 400-600 for a 20-30 min set on low 1-3 level but 10+ speed. it's basically running but without the impact.
You're in Florida, right? Some of us knuckleheads in the NE are fairly limited in when can run outside, unless of course we want to head out for our cardio looking like the little brother from A Christmas Story, lol...

possibly because they raise GH levels(a powerful cutter)
look at pics of pro sprinters vs pro long distasncers
Researchers show that HGH can be increased by as much as 530 percent through sprinting activities
