Tone It Up

[@Raddiebaddie]

Tone It Up This workout was awesommmmme! Thanks so much for keeping it fun while we tone. Sometimes I get bored and mentally that's the hardest part so thanks for this :) Is it possible to do a HIIT that won't make my downstairs neighbors want to kill me? :-/ haha, i'm thinking there are other apartment #tiusisters that are in the same boat!

[@MerMoleiro]

Can someone with an herniated lumbar disc do this kind of hiit routines? Thanks kk!

[@MechL66]

Mercedes Moleiro These workouts seem to be helping mine. My dr said it builds up the muscle in the area and makes my back stronger

[@MerMoleiro]

mmerci1 thank you so much!

[@sophiebuckingham6949]

I did this for the fist time in like June 2015, and now in March 2016! I'm loving it!! I can do the whole thing without even stopping!!! Before I could do like 5 jump squats, now I can do it for a straight whole minute!!!! So I really have to thank you girls for all the challenges!! THEY MAKE ME STRONGER!!!!

[@melissadunaway1358]

This is the first time I've been able to complete this workout! I'm so proud of myself!

Tone It Up is there any move I don't love?!! :))) Nope!! Since I'm working out with you two I can't wait for my daily workout! :)

[@marybishop6105]

Tone It Up Those burpee jumps!

[@xSuzieMx]

Tone It Up Reverse Plank Thrust !!!

[@megandietz5520]

Those tuck jump side openers! I wasn't too coordinated with those criss cross jacks. Definitely felt like Elaine on Seinfeld when she's dancing

[@barbarellaandco]

Tone It Up I love all the moves, but unluckily I have bad knees so, could you suggest me some variations for the tuck jumps and burpees jump? Thanks for your great workouts girls, you're such a good inspiration for me

[@taracardinal6789]

I love this workout! I come back to it often. I modify some of the moves and add extra rest time when needed. The jump squats and burpee/jump tucks kill me every time!

[@toneitup]

hey Tara! we all have to modify sometimes so don't be hard on yourself babe ~ SO proud of you for gettin' your workout in! love u! xxo 💗

[@arielleotero9008]

I woke up at 2am and saw that you posted the workout and was able to get right out of bed at 5 for my bootycall. This workout is AMAZING!! I'm still sweating and shaking. A minute has never felt longer. What an excellent way to start the day. xoxoxoxo A

[@SharonDidThat]

Ouch. My everything is awake and Ouch. But I'm still Alive. 51 and working on my Fabulousness. Thank you, Ladies.

[@hollowriver]

I have MS and I got to the jump squat burpee and thought lol (know your own body and with my illness I'll just do jump squats again.) My jump squats barely lift the ground. I lasted 16 minutes and called it quits. I'm proud of me. Never stop trying to get stronger is my goal! I feel good though.

[@toneitup]

Chrisa Sedore Big hugs to you!! You are amazing!!

[@hollowriver]

Awe thank you but you guys inspire all of us

[@MuseCatherine]

+Chrisa Sedore Great job!!

[@aimeedalrymple2730]

+Chrisa Sedore Well done, all you can do is go for it each time!! This is very intense and I take more breaks than the trainers, but I'm noticing that reduction after only 2 views of this video. Your body is your challenge, all the best to you xx

[@starmsjc]

Thanks for sharing your determination and perseverance with fitness.

[@daisyv6050]

I think it's great that you're listening to TIU members and viewers feedback on posting the videos earlier for east coast and international ladies. Can't wait to try this in the morning!

[@toneitup]

Daisy V We love our #TIUTeam so much!!

[@StephanieNicoleArtistry]

Criscross jacks look awesome! Also the sky in the background during that move looked beautifulll!

[@amandabarranco2776]

omg im so excited! Why couldn't this have been on the Beach Babe 3 DVD for 40 minutes.. i LOVE your HIT workouts!

[@justinemilon6701]

Thank you so much Karena and Katrina. This challenge just started, so my body probably haven't changed much. But this positive energy is so empowering. I've never felt this good in my life. I finally love what I see in the mirror and I feel sexy!! I can't wait to show this confidence off in my hit bikinis this summer!!

[@Marinaandthemouse]

Wow! I'm so excited. This is going to kick my booty. Lets do it #TIUteam!

[@HeyHunniBee]

Tone It Up You guys are literally my life and fitness inspiration! So much love for you both

[@addisonneria]

i haven't actually done a full on work out for months and this work out kicked my ass!!

[@12345saoma]

Addison Neria yeah girl, you go!

[@aherberg1]

I'm doing this tomorrow... so excited! I've been really sick the last 2 days so I've felt off without my TIU!

[@smoothielover07]

Can't wait to do this tomorrow morning! Thanks Karena & Katrina!! AND for the music-free version too! You two are thee best! ;D

[@missmelissala4113]

smoothielover07 heyaaa wheres the music free version? xx

[@nataliespear9526]

This was the first TIU workout I ever did. It is my happy place . Thank you!

[@lanus420]

This is by far the best Tone It Up workout on KZbin. Kicks my ass every time.

[@kristinashouse]

I love this workout!! It's one of my favorites for an effective HIIT burner. Always coming back! 💗💪

[@jillianlamoreau8638]

This workout always helps me gauge how fit I am! Just noticed it was published on my birthday two years ago! Ive been doing it on and off since it came out. It just got way cooler since it went up on my bday! Thanks K&K - you girls rock!

[@cristalc751]

I started doing this two weeks ago. I could't finish, especially the jump tucks. I've never sweated so much and felt my body work so hard. I'm glad to say I was able to finish the jump tucks (not at the same speed as Katrina), but I finished and I feel so much stronger!

[@shawnawalz]

Just did this to start my day- paired with one of your total body workouts and Karena’s ab video. Great morning routine!

[@jenniferscallorn5248]

awesome quick stand alone workout for when you're short on time and a great add-on for days when you've got energy and time for more. Love it!

[@jesserglad]

Did this as part of my 40 mins of cardio of Bikini Series 2016 day 3! This workout still makes me sweat sooooo much!

[@KyrasBeautyStation]

Ahhhhhh so excited! You ladies look amazing as ever and are my biggest inspiration! You inspired me to pursue a career in nutrition and I hope to get to one day meet you!

[@SimoneCorbettC]

EVERYTHING HURTS! But thats when you know you just did a bomb workout. Thanks Karena and Katrina!

[@BriannaFox]

Doing this tomorrow morning!! Cant wait!!

[@kloekat62]

this work out was amazing so proud of myself for completing the entire thing, doing toneitup workouts and my beach babe DVDS have really improved my fitness level THANKS

[@jencorallo8783]

One of the best w/o I've seen in a while. Thanks ladies! I'm fifty but I'm going to give this a try

[@Floglo]

This is amazing, this helps with my anxiety!! Helps me to get energized & by the end it calms me down

[@Capchip619]

One of my all time favorites! Thanks K&K

[@madhurimadas2616]

what a workou!!! probably equivalent 2 a 45 min workout...by far the best HIIT i hav seen!!

[@WonderGini]

I love how Katrina always has the perfect form while performing moves.

[@birdseed41]

Yay! Can't wait for tomorrow morning, thx for posting early ❤️

[@LeanneHubert]

Holy Crap. I did not expect this to be as challenging as it was! I literally could not complete the full 60 seconds for some of the moves (i.e. the burpee) but I still finished the entire workout! New goal for me: be able to complete the full 60 seconds for each move! Thanks Karena and Katrina!! xo

[@brookelafrenz7635]

What a great workout! I will be coming back to do this one again! Now ready to take on the day with my kids.

[@kimboslice10kh]

i am really loving you guys! been subscribed for a while, but till now im actually doing the workouts its so hard but you guys are a great motivation and i really want to keep this going!

[@breannakatherine09]

Even after months and months of working out daily, this HIIT routine is the toughest I've ever done! Holy sweat!

[@amandathomas7305]

Just did this for the first time and don't think I made it through any round without a break! But such a good workout, will keep coming back and trying to improve. Thanks K&K!

[@toneitup]

Yay!! LOVE that! Each time will get easier and easier!! xoxo!!

[@jstarheim]

My favourite TIU workout. 20 mins and challenging. How about some Fall themed workouts like this??

[@Floglo]

Love you guys! this is now part of my regular weekly workouts and I am starting to feel stronger! Thank you

[@megano.3434]

Holy guacamole, Karena & Katrina!! I'm literally dripping sweat after the Hitty Bitty Bikini Workout! Wasn't able to do every move for the full 60 seconds, but this workout is saved in my favourites and I'm going to keep doing it until I can! Thanks for being such awesome trainers! Recently discovered you girls and I'm so happy I did! Off I go to do the Bikini Yoga Flow!!!👙

[@Usersf34]

this was what i needed to shake up my run today, it's also sunny in the UK so i definitely visualised being on the beach with this one :) ! THANK YOU.

[@roxanepogut3409]

Just did it and it was AWESOME ! Easy to follow but so hard at the same time !

[@meganhilands4043]

Color me impressed with this HIIT!! Distance running has been my preferred exercise for years but I developed an injury this summer and I was looking for an alternate workout. I stumbled your channel and have been doing your workouts almost daily! Even though I was doing fast-ish 5-mile runs before I started these, I break a serious sweat during the HIITs. This one is the most challenging in my option. That jump-tuck/ burpee move is a killer! I also bought some of your protein powder after seeing the stellar reviews it got. Glad you offer vegan options!! :-)

[@springtime1009]

Who needs to go to gym when I can do this exercise at my own place without an expensive equipments. Thanks ladies!

[@aandrejjka2]

What a nice surprise! I was just about to look for a workout video to do now before breakfast! wohoo :)

[@dfranklinify]

When I did the HiityBittyWorkout the first time during the #bikiniseries I thought it was so hard and struggled to get through, I do this one at least once a week now and absolutely LOVE it! I seriously can't get enough of it! I love that I work up such a sweat and it's under 20 min. Thank you thank you Tone It Up!! xoxo @dianamfranklin

[@toneitup]

Diana Franklin You are amazing!! Big hugs to you for all your hard work and dedication, XOXO!

[@sophiebuckingham6949]

+Diana Franklin YES!!! Same, thank you TIU!!!!

[@josiebaez3520]

I have done this for a while not consistently but intravenously with other workouts and this never gets old, always the same intense feeling like I am about to pass out! Ty K&K

[@madisonchiappetta]

this workout had me dripping sweat! this is my new workout!!! ty girls so much

[@mandytjart]

This video is killer! I'm literally dripping with sweat!! This, hands down, is the hardest #TIU workout!

[@araceliluna4625]

One of the best HIIT workouts I've done. I am going to incorporate this at lest 2x a week in my workouts.Thank you for kicking my butt!

[@ed6954]

Go Kat, go! I could only do half of those burpee jump squat moves!

[@kenyamvaughn]

WOW!!! This workout is exactly what I need!

[@pamela1063]

holy cow! I just did this workout for the first time. I couldn't keep up, bet then again I haven't been working out for a long time. Need to keep my motivation going. I didn't do solid 30 seconds on every move but did my best and kept jumping back in. Definitely sweating and breathing heavy. thank you!

[@KellyPatootie]

Wooo I can take on anything in my day now after this! The burn.

[@ErinHonor]

This is by FAR the best HIIT routine I have seen from you guys yet! So much fun and so challenging. Can't wait to see more! Just wondering, are there going to be anymore HIIT treadmill routines like there were in the bikini and love your body series in the past? I loved those so much and still use them today and would love more! =)

[@personaltrainer1097]

I love your workouts !!! Very well done. Very impressive. Thanks.

[@jaspreetkaur9575]

Haha love the description- 'I-have-crazy-trainers workout' and loved the workout itself. Left me drenched in sweat. Couldn't manage a single curtsy lunge though, my legs just don't work that way. You girls rock!

[@Ayre2]

Omg out of this world workout! Love the silver sports bra!

[@agolympians1911]

WOW! This was so great! I've tried so many HIIT workouts but never found one that worked for me. But this one was AMAZING! I just finished the whole video! I'm sweating from head to toe! So excited to do this tomorrow! Thank you so much for this awesome video!

[@mariaheveritt96]

Now this was a workout! I would love it if you made more videos like these! wow so awesome!

[@andreaciciarelli8773]

WOW! This workout targets every part of the body in so little time. The best total body workout I've done/seen yet!! You girls rock! B-)

[@Littlemisseeyore96]

I have never been so tired after a workout! Those burpee jumps were a little too advanced for me so hopefully i'll get them the next time I do this!

[@anastasiakef5234]

Never have I done such a hard workout in my entire life! At the end I was crying with relief😂

[@sara54501]

Holy holy cow I struggled through this and didn't do so well on so of the moves but I tried and kept going. I love how fast and furious this is. I feel like with HIIT you really get the most bang for your buck. Do you have other HIIT videos?
