[schubek1982]

hey nice arm muscles! could you show your strength with an armwrestling match against a boy or girlfriend?

[swedo23]

you really have big muscles!!!

[kingchilliez]

try extending ur arms fully

[strong1235]

Show your body full length next time to prove to the haters that you didn't have any help! And see how many situps you can do in 9 min 50 seconds!

[muhslegit]

2:14 haha

[crooklyn817]

Damn shes stronger than me and im a guy :(, i need to work out.

[batts1150]

[PigBeata]

My neck got caught up on that one time and i almost died.

[uuukkjj]

[maca586]

Try doing a video with u liffting weights and longer flexing as well in a tank top and try show your muscles when ur doing ur pull ups and weights

[strong1235]

She is not afraid to go for her max! Love to see you show up most guys with a max at hands behind the head situps and leg raises!

[weackychicky]

Great work..:D

[bk12bk321]

Very good. Try "flexed arm hang"!

[123meatstick]

could u do a stretching vid and splits?

[AndyAngelZ]

show ur whole body please

[wdw1]

You have some muscular arms and your legs look really muscular as well. Awesome!

[AndyAngelZ]

is some1 spotting her or somthing? it looks like someone's holding her lags even tho u cant see

[cardfan13]

You are adorable, but work on a more full range of motion. On your overhand chinups try a wider grip. Still it was very impressive! My favorite exercise!

[gymnasticsmuscles]

Great pull ups and flex at the end!

[Fastidious01]

I gave ya 5 stars!!

[UraganOtEnergiya]

Amazing!

[mygymgirls]

oh do u think u can make a video of u holding a chin up for a minute... we do it everyday at practice.

[Antony777777]

I'm Impressed.

Do a flexing video, you seem to have the potential for it

[benjamin199000]

haha ur friends r explaining ur not cheating with the chin ups but its clearly shows u dont go full way down much harder that way but its better exercise ;)

[TaylorThaHick]

Hi Casi, that is really impressive. 

Make an arm flexing video, we want to see you in motion. Gymnasts have MUSCLES, right? :D GO for it!

[fitgirl78]

That's awesome, you're definitely very strong! However, you have to go all the way up and then all the way down, otherwise it doesn't count as a full rep. Your elbows stay bent and you're only going down halfway. Try full chins and pull-ups, I bet you can still do quite a few.

[swedo23]

handstand pushups next?

[XanthiJr]

You're strong.

[MrEtc]

Nice :) You should try 100 squat thrusts in a row next lol

[bluetennisball]

their not fake i'd like to see you do those!! casi is probably the strongest girl in our grade and those r NOT fake

[luvkitties246]

agreed!

[Legman007]

great vid. great arms and arm strength

[luvkitties246]

okay, i'm one of casi's best friends and i know for a fact that casi is an amazing gymnast and would never cheat. (as if she would even need to?!) way to go cas! :) love you!

[einsteinsdad]

Casi, With everyone saying you 'cheated', why not do 25 chinups again showing your entire body? I know it is possible to do that many, but it's not easy. And I'd like to see you do as many one-legged squats as you can.

[Pajamasandrobes039]

ok fine!i filmed the video of my entire body...the only reason i did it so close was so people could see it better...you people are really stupid to think a gymnast would really cheat on pull-ups....unbelievable....th­e new video will be up sometime next week when i can uploead it.

[nasaguy]

Thank you! Sorry for doubting you. We do appreciate your efforts and your videos, we really do!

[armf123]

when will it be up?

[nasaguy]

Hi Casi - I was wondering if you could post your updated video of chinups? Doesn't matter if you got 25 or whatever, you're STILL awesome! Most fit people would kill to be able to do what you can. :)

[jayg2009]

how is she cheating?

[aron3535]

=O...WOW youre amazingly strong!

[nasaguy]

Wow, thanks for doing the request Casi! You are super-strong. When you're rested, would you be willing to try it again, with a full-body shot?

And how are the pushups going? :)

You rock,

nasaguy

[asteroidedu23]

wow,nice video

how old are you and how do you weigh?

[bluetennisball]

[delciouslyrandom]
