Are there any effective HIIT exercises that can be done in the gym? Treadmill is a no go due to the difficulty of the controls at an extremely fast pace. Haven't really tried it on any other machine. I normally do my HIIT outdoors but I need something for the incoming winter season. Tips? Ideas?

Ellipctical, rower, bike, etc.

It's all about effort and heart rate, so anything you can do as SS cardio, you can do as HIIT.

Everything in this thread seems to state that you have to go "all out" for 10 secs to 1 min. I am a little scared to go over 10 miles per hour on the treadmill because of the threat of falling. But this is not hard enough for me. Any thoughts?

I have done it on the treadmill (yes, running on those things at 10 mph is a little scary at first, but just be careful), the stepper is effective as hell, bike is good too...

I'm careful
How fast have you gone on a treadmill?
Thanks

Well, the ones at my gym max out at 10 mph, which is decent. I'd be better served going on a track since I feel like I might be able to sprint at 11 mph or better, but it works fine for me.

I've recently found that the stairmaster works well for me for hiit. I set it on manual and do:
1 minute warm up at level 10
30 secs at lvl 1
30 secs at lvl 20
30 secs at 1
30 secs at 20
45 secs at 1
30 secs at 20
1 min at 1
30 secs at 20
1 min at 1
30 sec at 20
2 min cooldown at 3
My heartrate gets up to about 95% of my max.
This seems to be safer than the treadmill and more intense than the stationary bike.

Use the bike.

Bike works pretty well. Stairs get your heartrate going a little bit more and a little less leg fatigue.

anyone use a rowing machine for hiit?

just wondering which machine would be better for hiit for my home gym: recumbant bike, rower or stepper. thoughts?

I have used a rower. It's a good one, but since HIIT is all about heart rate and intervals rather than any particular form of cardio, the best one is going to be the one you use regularly.

However, avoid the recumbent bike and go with an upright, if you go with a bike.

try increasing the gradient on the treadmill before the speed that will make it harder without going to fast.

Do you have to be on level 10 for HIIT? I usually run between 6.5 - 7.2 and that is EXTREMELY tough for me to do. Granted, im doing my HIIT for 5 minutes..maybe I should go faster for a shorter time?

I would.
At my highest intensity, I would not be able to run for 5 minutes...
i ususally do just 1 min per interval..
but it really depends on your heart rate

jumping rope is a good way
