Sometimes i don't even do the exercise remotely close to what u are doing, i am just wiggling around like a worm. 😂😂😂
This is my face😖😖😖😖😖

I almost did it! Had to stop a few times, but I'm a beginner so i guess thats alright. Day 16, ♥

[thebestvillager]

Wow I was not prepared for that. This is abs on fire times three. Soooo painful but so good

[beverlyaboateng]

I really don't understand how cassey can do this all without stopping and have a conversation as well because I stopped a few times and just listened her and ab days are my least favourite because I'm so weak :')

[michelletapham]

I love how she know's when you're having thoughts of slacking. Her encouraging words brought me up all right !!!

I used grapefruit as a weight and on 8 min stopped video for a little rest but insted of this i just insensibly ate it. I`m :D

[jessicab.]

Did the whole thing without stopping for the first time! Slowly, but surely making improvements!

[ginaabobina]

I used a candle so every time it went by me, it smelled good and made me wanna do more! Haha :)

Day 16 of the beginners calendar! I know, I'm a little late 😝😝 I was actually a tad excited to see hollow rock (I know. I'm a bit crazy) but I remember feeling the burn last time and it felt so good! ..and then I got to that part of the video and I barely got to do any cause I was so. Burned. Out. And. Tired. By the time I got there but yay for getting through it!

[claral]

When you see hollow rocks and you're wondering if this video is really /that/ important, after all

[kennylee]

i got my periods in the middel lol but i done my things and continue. beginner calandre day 16 done.

[LivandletLiv]

I did this yesterday for the first time and thought ' that wasn't as hard as I thought it would be.'
This morning I woke up and it hurt so much to sit up I almost cried! Thanks You always know how to work us hard! Xxxx

[ThatGibsonGirl]
