stairmaster is king of the cardio equipment, id rate xtrainer 2nd then treadmill ..... i wouldnt use anything else...... theres just somthing about the stair master that knocks the fuck out of you.. improved my legs no end cuts wise last time i stepped on stage , was night and day from just a few month prior
how much u wanna do and how hard u wanna do it all depend on what your goals are,,, just generaly looking good or gettn ripped... if your wanting to be dripping in veins you have to do whatever is necessary to get the last few ounces of fat off, even if it means 2hrs plus each day
