Re: HIIT in a gym?
Didn't read thread carefully, so sorry if this has been mentioned:
You can absolutely do HIIT on ellipticals. Because I have injury prone knees, I don't like to do HIIT by sprinting outside or on treadmills, so I use ellipticals and it kicks my ass. I crank the resistance really high for 30 seconds and go balls to the wall, then make the resistance to the near lowest setting, and take it easy for 30 seconds. If this doesn't make you out of breath and/or near puking, then you probably aren't doing it right.
