Obsessed!
I love this app! I’ve tried a few different workout apps & this one is by far the best. The workouts are super varied, so I never feel bored. They’re also challenging & fun & extremely time efficient. I love the voice over feature where Erin explains proper form…I find this to be game changing as far as making sure each move is effective. You also have the option to mute so you can listen to whatever you want. Most importantly I’m seeing great results! I can’t recommend this program enough.
Hands down my favorite
I’ve tried so many different apps.. this is by far my favorite. It’s easy to use, easy to follow, and I feel SO good when I’m finished with a workout! It makes staying consistent a lot easier too.
The BEST fitness app!
I have done so many different types of workouts but I always come back to the Pretty Muscles app. It is easy to follow and most importantly, it’s FUN! You can modify the workouts for ALL fitness levels to make it your own. Hearing Erin describe each move/workout is key! I’m always adjusting my form and pushing myself harder based on her verbal cues. It is worth every penny and you will not regret it. Not only will it transform your body, it will transform your mind and how you look at fitness…like it has for me.
It works!
I am loving this app! The workouts are amazing, you can tell Erin really put a lot of thought into making each workout. I used the beachbody app for years and never noticed the change in my body that I am seeing with using the pretty muscles app for just a few months.
Love, love, love!
I love that the workouts are all laid out for you and you work on different muscle groups each day. It’s a very user-friendly app and Erin shows you how to do all the moves. It’s great for all fitness levels and you don’t need a lot of equipment to get the workouts done. Get it now.
Pretty fun!
I am loving the Pretty Muscles app. I have the “fancy” bike and it has been good for cardio But…sinc pandemic I was floundering with a personal routine off the bike. What I love most about PM is the variety while still getting the organized feel of a planned/trainer workout. So many apps leave you on your own to “patch” a program together. This feels like personal training and is challenging. I appreciate Erin’s humor and her timely reminders for proper form. So glad I tried Pretty Muscles! I am hooked✨
Amazing workout
Erin’s workouts are tough, I’ll start with that. They are not, however, impossible! She offers alternatives to moves so that it’s beginner friendly and enjoyable. As a former athlete who fell out of love with fitness for years (like 10 years), Erin is helping me find my rhythm again, and I am finally enjoying working out like I used to! I cannot recommend this app enough, no matter what your fitness level is!
Fantastic!
2 kids later and 50 lbs heavier, I’ve tried a few different fitness apps, but THIS IS THE FIRST that has made me sweat this much! I’m so excited to see the long term results from this awesome fitness program. AND it has fun incentives and a great daily routine for muscle focus, cardio, full body… you name it! 💯 recommend.
Terrific
This is a phenomenal app. Erin has DELIVERED! Efficient and effective with a smart attention to detail and form. No circus moves, just clean simple moves that dig right in to allll the bits. Her selection of sequencing also is beautifully designed to truly build pretty muscles without bulk. Genius! To top it off Erin’s energy and spunk make it so fun. This is a fabulous tool in my toolbox. I LOVE it!
Amazing Results!
I started following Erin Oprea on Instagram a few years back & have been using her app for over a year. Erin has a special gift of making exercise challenging yet fun. The PM app has been a blessing on my fitness path—I’m a 50+ woman and was sick of trying to stay in shape with running and cardio classes. Erin is the kick in the shorts I need daily and continues to be that mantra in my head that says if it doesn’t challenge you, it doesn’t change you. I recommend this app to anyone who is willing to do the work to see amazing results! If it can work for me, it can work for anyone.
