Hello everyone, recently been going to the gym at a later hour in which only the late night regulars are around. As you would think, this leaves a lot of the equipment open for use when it previously would have had an hour wait line to it. For example, the prowler is open to use now! I tried it out a few nights ago but I was really sick so I didn't get a good experience out of it (mostly me wheezing and struggling to breathe)... But this brings up the point about different types of cardio and which ones are the most effective and unique for specific styles of training. So of course everyone knows there is steady state (which is still a bit controversial in accordance to maintaining muscle), HIIT, circuit styles and many more. How well do each of these work for maintaining muscle mass but increasing your cardiovascular heath?

My other question is what about cardio like boxing or MMA? Some people really like fighting for cardio (like Mike Rashid). Or what about the prowler? Is the prowler only able to be used for cardio? I don't see very many bodybuilders in my gym using it but that's just my gym. Any of you guys ever use different forms of cardio besides the stair master, treadmill or bike? Oh yeah, almost forgot to mention we have a Jacobs ladder too! For some reason, at my gym only the girls use it I don't really know why... Is it any good??

I'm really curious about this!
