Shape, firm and lift your booty in only 5 minutes a day.

With Killer Butt, you'll learn the secret moves to sculpt those hard-to-reach areas and get a butt that makes them look twice.

With Killer Butt you can do a quick 5-minute tone up whenever you have a free moment or you can push yourself with a killer 15 minute workout. Every workout is customized to your fitness level and to the equipment you have available.

Each exercise includes an audio description to help walk you through the movement and a video you can view DURING YOUR WORKOUT, so you can always double-check your form.

• A complete leg and butt workout everyday. Strengthen and tone your butt and thighs quickly and easily.
• Workouts customized for Beginner, Intermediate, and Advanced exercisers.
• Over 70 unique exercises. Each one includes a video and audio description to help you perfect your form.
• Works anywhere! Over 30 body weight exercises to push you to your fitness goal. You can also add in equipment if you want a little extra challenge.
• lolo's beat-sync technology perfectly matches the tempo of your music to your workout.
• Completely interactive. Swap out exercises to personalize your workouts. Increase or decrease the intensity at anytime and your trainer — and your music — will respond!
• Sync your workouts to the Health app.
• Compatible with most bluetooth heart rate monitors.

Killer Butt dynamically changes the beat of YOUR music to perfectly match your movements. Research shows that music distracts the brain during exercise and faster music causes people to accept and even prefer a greater degree of effort. This means you will work harder without trying (or without even feeling the difference), you will get better results from the increased effort, and most importantly, the time will fly by.

lolo Connect allows you to save your fitness results to the cloud, track your progress across lolo apps, and share your success with friends and family through social media.

Killer Butt features an interactive personal trainer whose voice guides you through each workout, giving you the tips you need to get the most out of your workout and the motivation to keep going no matter how tough it gets. Killer Butt gives you complete control as you move through your workout. Turn the intensity down a bit when you're struggling or crank it up when you're ready for more, and your trainer adjusts your workout - and your music - on the fly.

Whether you're a beginner or an athlete, Killer Butt will design the perfect program to match your schedule, equipment, and fitness level.

Your personal network is key to reaching your goals. Share your successes with them through Facebook.

Good exercise app

Overall this is a good app, easy to use without special equipment and intermediate was right for my fitness level. The routines are short and can easily be accomplished before waking up the kids in the morning.
My only complaint is that the voice counting the reps goes at the same pace for every exercise even though some forms take longer than others. I am always behind the count. Please fix this.

I was so excited to try out this app. In order to open the app, you have to have an account. For the past two hours, I have been trying to register. All it says is registration error. I am so upset that I wasted my money on this. Please don't purchase this app!!!

Beautiful interface and challenging training

I have to say that I love all of the Lolo apps. I love that you can tailer each workout to your level, time frame, and available equipment. It's also great how a video of each exercise plays as you are doing it... Especially with the more difficult positions and movements. On top of that I actually feel challenged with the excercises, and see that my body looks more toned and I feel stronger. I was thrilled that they made the killer-butt app.... It totally holds up to the high standard of the other Lolo apps. I'm a fan forever.....
