I really enjoy looking at the differences between programs and when I have time, I like to dig a little deeper and share my thoughts in case any of you would enjoy discussing and adding your own perspectives ♡

 Some caveats:
• can't guarantee my data entry is perfect
• does not account for warm-up/cooldown time (I often encourage people to pick the ones they like best/have time for rather than the scheduled ones)
• but I do include all other optional workout videos in my data
• the minutes are rounded
• /day is minutes/day
• videos with mixed focus are split between the categories
• this does not account in any way for actual intensity of the videos themselves, it's purely looking at time in minutes

 My thoughts:

2019 Lean Thigh:
• Definitely the most time-consuming schedule of these three programs, and the longest average daily workout length of any program I've analysed yet! There are some optional workout videos, including an entire optional day in Week 1. The schedule has the potential to feel a little intense as the program starts off with two 6-day stretches, but there are more regular rest days as the weeks go on. Personally, I would choose to take a few extra rest days so that I'm always getting at least two rest days per week.
• When deciding how to categorise the videos between "cardio" and "lower body," I looked at the speed Chloe chose when doing the workouts. So even though some videos might be titled in a way that would imply "lower" and use the legs a lot, I still deemed them to be more fitting to the "cardio" category (this is a thought process that applies to all of my program breakdowns!)
• As is typical with older programs, the video variety is fairly limited. There's two abs videos that are repeated (and I hope you like planks because the plank challenge video appears 16 times!), two cardio videos, and two lower-body focused videos. If you struggle with repetitiveness, you could swap in different videos from those categories to keep it feeling more interesting.
• Why should you pick it? If you're up for longer workouts, don't have any equipment, want to work your leg muscles and core without much upper-body involvement, then it may be a good choice.

2020 Slim Thigh:
• This program has long had a reputation as a more beginner-friendly program, and it certainly has a more approachable schedule and average workout length than Lean Thigh.
• The balance is shifted much more towards targeted lower-body work, with less average cardio and core. There is a standing abs video that appears 12 times. I tend to think it's best viewed as cardio rather than as core (as categories go), but it's still a good blend and I actually enjoy that video quite a bit.
• Again, the video variety is a bit limited. If you struggle with repetitiveness, please do swap in different videos to keep your enjoyment level higher!
• Why should you pick it? If you want a little more approachable schedule, don't have any equipment, want to primarily focus on your lower body with a bit less cardio/core and no upper body, then it may be a good choice.

2019 Lean Arms:
• This program has a very approachable workout/rest pattern, with no more than three workout days in a row. The average workout lengths are a little longer, especially in comparison with more recent programs, but regular rest days definitely help keep the intensity level down.
• The only program so far with an upper-body focus, making it unique! There's still plenty of cardio and core work, but you will absolutely feel the focus on the upper body.
• On a personal note, this is the only program of Chloe's I've ever quit without finishing it. Something about the volume or move choice ended up being uniquely stressful to my shoulder, and while I genuinely enjoyed several of the videos, I decided it wasn't a good fit for my body at that particular time. I include this as a reminder that it's always okay to stop a program if it does not work for you, and it's always okay to swap out a video for something different if you don't enjoy it or it has moves that are stressful to you ♡
• Why should you pick it? If you don't have any equipment and want to primarily focus on your upper body, with secondary focus on cardio/core, then it may be a good choice.

Have you done any of these programs? What did you think of them? Please feel free to share your impressions/experiences, I love to hear them and other users find them so helpful!
