Hey guys!!

Hope you’re having a wonderful weekend. I just filmed your new Flat Stomach Fat Melter video yesterday and got it up in time for your Monday workout on the #AprilAbs Calendar! Woohoo! This one is INTENSE. It’s a combination of sweat-worthy HIIT moves and some of my best and newest Pilates abs exercises:

1. Squat Claps

2. Lengthened Ab Holds

3. Single Legged Burpees (yup, I just said that)

4. Inching Caterpillar

5. Plank

6. Jumping Reptile

7. Ballerina Leg Outs

Oh! And I am SUPER obsessed with my new shirt featuring hipster beast. I mean, look at him.



He’s cute and effortless but he so isn’t fooling around. He’s gonna go beast mode with you 🙂 The shirt comes in Black and in White like the one I wore in my video. Click here to shop.

Also, this video was LONG OVERDUE but it was a post natal workout I filmed with Colette Butler of the Shaytards family! It was so fun exercising with her and baby Brotard! Watch this video for a good laugh even if you don’t have a 14lb baby to use as a weight 🙂


It’s important to be active before your pregnancy, during, and to get back into exercise once you feel ready to after you’ve delivered. Like Colette said in the video, when she was instructing fitness classes during her pregnancy, she bounced back wayyyy faster than when she did not. Her body was much more resilient. It obviously doesn’t have to be anything crazy intense – you just gotta keep the momentum going.

Oh! And watch til the end. Somebody gets jealous and it’s good.

Alrighty guys, hope you have a MAGNIFICENT start to your week!

<3 Cassey

    I’m totally going to have a go at this. I need a bit of a fat melting session!

  2. debbie says:

    Lately I haven’t been able to view these videos. Is there a problem with youtube? I get a green screen that wiggles so I had no idea what some of the exercises were.

    Dear Cassey,
    I am a 23 year old mom of two boys. Time is pretty pressed to get in a good workout with a preschooler and a toddler. Is there a workout you can suggest or do that they can do with me? My toddler is a walker and doesn’t enjoy it when mommy is working out lol and I need something he can somewhat do too! My 5 year old LOVES your workouts, but some days they’re just long workouts and I’m hardly up past their bedtime, so working out after bed is hard. I have tried early morning workouts, but they just wake up lol. Our walls are pretty thin!! Help please!!!!!! 🙂

    Hey Cassey, I’ve been visiting your Youtube channel on and off for 1y and a half now, and it occured to me that you’re one of the few trainers to actually OFFER your workouts, and I wanted to thank you for that.
    I think nowadays, “poor” people are the ones who eat the more junk food – by choice or not – because it’s cheaper, so I appreciate that you stay true to what you say about wanting people to realise how much good stuff working out can bring in your life, and offering possibilities to try your workouts before buying the DVD.
    (I’m not saying everyhting should be free, I get that fitness trainers have to earn a living, but maybe 100$ a DVD isn’t necessary…)

    Could you please make a short (5 isn min) High intensity butt workout.

  6. Ashley says:

    Oh please please do more post baby workouts!!!! I love your workouts and your videos and I just wish there were a few specific for moms working out post baby or people with diastasis recti. For the whole body!! Let’s get rid of those “mom wings” and “pudgy tummies” and “thunder thighs”!!! All taking in consideration what the mom’s body just went through over the pas year. The other videos online just aren’t as fun your videos! 😉 They could really use a bit of “Cassey Personality”, if you know what I mean… lol

    Would you be able to make a chest workout video? I’m always searching for perky boob exercises and nobody makes workouts better than you!

  9. Robie says:

    Is there a printable for this workout out? 🙂

  10. paige says:

    hello, i am really into getting a tone body. Im 16 and weigh around 145. I play on a high performance sports team and understand that 50% of it is muscle. Though i really would like to get a flat(er) stomach and thin my muscular legs? Any ideas how to help? or any routines to follow?

  11. Lynn says:

    Such a cute video! The jealous baby made me smile! 🙂

  12. Bronwyn says:

    Thanks Cassey! Expecting my second daughter this summer and keeping fit with Pilates, yoga and low-impact cardio. This video is perfect.

  13. Jennifer says:

    Hey Cassey, I loved your video-like always. I just have a question, are we supposed to stretch everyday before and after the workouts even though its not on the calendar?
    Thanks in advance, your Popster Jennifer

    1. Jennifer says:

      You should because it’s better for your body and muscles to stretch before and after to have the optimal performance. It really helps you perform the moves better! It doesn’t have to be long!

      1. jennifer says:

        thanks so much! very helpful! 😀

  14. asal says:

    thank you so much Cassey, you give me so much motivation to carry on and workout, love u

  15. Yousef says:

    Very nice ! Cassey all of your workout are amazing but ….. Sometimes I have no energy to do it I feel lazy what should I do ?

    1. Jennifer says:

      Hey i know im not Cassey, but i wanna give you some advice. If you really want to be fit this, you need to disipline yourself. You really need to want it-if you really badly want it you should just need to get up and do it. Laziness is a choice, and if you want this you need to choose no to be lazy. Hope this helps.
      P.s. I have these “lazy” days alot so I hope you dont feel like Im judging you. I am only speaking from experience. have an awesome day!! 😀

      1. Yousef says:

        thank you very much on your advice

        1. jennifer says:

          Glad I could help 😀

  16. Catherine says:

    I actually think one legged burpees r easier then the regular burpees

  17. Stefania says:

    Dear Cassey, I’m really in love with and I love having the calendar there, but please please I’d love to comment (and read the comments other popsters write) below the daily playlist! That’s what I liked the most about the old playlists… this way I feel “alone” in my journey despite being part of the social network. So yeah, thanks again for everything you do (I’m finishing a regular calendar for the first time and it’s amazing seeing how stronger I get week by week), and please add a comment section below the daily playlists! Bye <3

    1. Jackie says:

      I agree! I love but do agree that I miss the comments section underneath the daily playlists. Sometimes when I don’t feel like working out or if a particular workout seems really challenging that day, the comments often motivate me to keep going. I also like to see if other people had the same difficulties that I did with certain moves.

    2. Noami says:

      me too! please bring them back! 🙂

    Thank you Cassey for this workout for mums. You have helped me alot during my 6 month post natal. I´ve lost 16kg in 6 months (my youngest is just 6 months) and i have to thank you for the work you do. Due to the videos from your webbsite, i´ve got a good posture, which help me when i carry my Children, and all my work at home. I have a nicer body than i every had before my pregnancies. So i want to thank you. I hope you read this.

  19. I love your abs videos! I’m always happy whenever I see definition in my abs, thanks to your awesome videos!

  20. Anna-Kaisa says:

    Yay I loved the Fat Melter workout! I really loved the Flat Belly Fat Burner so this was quite a similar format which works for me! (even though they are crazy challenging!)

    P.S. Commenting on the workout playlists on the my.blogilates social network isn’t working 🙁 no biggie, but just thought i’d let you know! 🙂
