I switch it up throughout the week. I will try to do 2-3 higher intensity sessions and then 2-3 moderate intensity. The stair climbers will kick your butt if you push yourself. If I'm really tired or really sore, I'll use the elliptical.
I do the treadmil, going to start doing some jump rope
Would love to do HITT but the way our gym is set up here it's hard, everyone walks behind the treadmils, im scared ill fuckin blow off it and take someone out lol
I do HIIT on the treadmill - crank it up to 15% incline and alternate running with walking.....it will totally kick your a$$! I do the stair machine sometimes just to mix it up a little......
