I tried it just to try it. I have a peloton treadmill and bike and use both regularly, averaging 70 running miles and 100 biking miles per month. Also I do weightlifting.

The cardio is less challenging than running and cycling. But it really targets the glutes and hamstrings. I thought it was a nice change and the pace is slow enough to watch a show (I have the peloton treadmill beta that allows me to watch Netflix on it). I wouldn't do it daily, though. It focuses too much on one muscle area. Cross training with running or speed walking would be better than just doing the 12 incline all the time.

I have back issues and I definitely felt it the day I tried this and didn’t last long. I have to be really careful about what I do if my back is acting up.

My ankles don't like the 12% incline but I did 5 miles at 4.0+mph and 9 or 10% incline for a few years and was able to eat whatever I wanted while dropping to and maintaining my HS weight. (I will apparently do anything to avoid running)

Op here- I did it with 30 mins with lots of breaks at 10 incline. Wow what a workout! Will try it again soon!

It is definitely not easy. I say that as a man OPs age is that can run about a 1:30 stand alone half marathon right now.

OP - just get after it! Don’t forget mobility and stretching, especially your hips.

Definitely not easy! I am trying the same thing, op, but I’m starting at 60 minutes at 3-4 mph w 6% incline bc I found I wasn’t actually making the time for 12-3-30 bc I found it pretty unpleasant-hopefully that will change!

That’s a pretty leisurely pace. Not sure how that would get your heart rate up. But anything is certainly better than nothing. So go for it.

NP: Leisurely? have you ever walked on a 12% incline? Try it, I dare you.

I do it occasionally on days I want an easier workout (I usually run). I still have yet to make to a 12 incline. I’m at 10 right now. Granted I only do it a few times a month so I’m not used to it.

OP start on a lower incline and work your way up if 12 is too high to start.

Yeah, you should try it before you say that. I found it unbearable, and I work out daily! Even knocking down the incline to 10 is tough.

It does because you’re on a steep incline. I don’t use the treadmill much but when I’m walking I do this for awhile and it does get my heart rate up more than flat walking at a higher speed.

No idea what this means

I am thinking about starting the 12-3-30 to get in shape. I am 41 female with 2 children and have gained 15lbs in last year so would like to get in shape.

Any tips?
