I just rejoined iFit.com. I have an older NordicTrack C2150 treadmill that I bought in 2012 and it has a 10" display. They recently started "retrofitting" their instructor led video programs to work with equipment that is older than 2015. There are some AWESOME programs available for iFit enabled treadmills, incline trainers, and spin bikes.
If your treadmill has the "track" display (not video) and it's iFit enabled, you can get the program to load but it will just control the treadmill without the video. Not as much fun, in my opinion.
I enjoy the outdoor programs that are filmed on locations. Right now I'm doing a Beginner running program that's six weeks long that works up to running 30 minutes straight (at a slower pace of 4.8 mph). It was filmed in Portugal and Morocco with Tommy Rivers Puzey who is an amazing endurance athlete that has tons of running tips, form pointers, and location information. He has a degree in anthropology and he's also a Physical Therapist so his runs are very informative and fascinating. There are several programs that "build" on this so I can progress with him or another trainer. (I'm working my way back to mostly running again after a hiatus of run/walking).
If you prefer to walk, there are several walking programs as well. Hanna Eden just did a 16 workout program filmed in Bolivia. Beautiful scenery and very doable for all fitness levels (you can lower the incline or speed when needed). I did one of the workouts from this series yesterday and LOVED it! She is so encouraging, funny, and friendly! Nothing like her hard core persona on some of the videos I've seen of her. I'm going to keep adding these workouts as a nice change and because they are so enjoyable.
This rediscovery of iFit has renewed my passion for running (and incline walking) again! I have always been a "video" workout person and this feels like an extension of that on my treadmill. I'm never bored and look forward to getting on it every other day.
Oh, and I was able to buy a yearly subscription a lot cheaper than paying monthly...from a third party.
