I really enjoy looking at the differences between programs and I've done breakdowns for a few different series, so I've started sharing them in case any of you would enjoy discussing them and adding your own perspectives ♡

 Some caveats:
• can't guarantee my data entry is perfect
• does not account for warm-up/cooldown (I often encourage people to pick the ones they like best/have time for rather than the scheduled ones)
• the minutes are rounded
• I count anything "full body" as cardio for this type of program
• 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:
• just purely looking at minutes, the programs are pretty similar - I think this is definitely a situation where the actual intensity of the videos used may have a bigger impact on the feel of the program than the time spent
• technically there's not much dedicated upper-body in any of these, but since a lot of core work involves plank variations, it may help balance that out
• 2019 is great if you enjoy its videos, but you may struggle if you prefer more variety
• 2020 has the most cardio/full-body and the longest average days, which makes sense as it's considered the hardest of the three 2 Week Shreds
• 2021 has the most video variety and the least dedicated core work
• Intense Core has the most dedicated core work and the least dedicated upper-body (but again, planks!) and second-longest average days


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!
