I love the back and abs combo. Back is my favorite part to workout and the abs at the end adds to that burn a little more. ;)

I'm so very grateful for this program with Ektfit, not only did I gain strength but I saw what I was made of. I passed my goal and I feel like a winner 💫 this challenge came at the most difficult time in my life. My father-in-law passed away, my husband just lost his job the very next day we found out they were closing his company's cutter in 5 weeks, I found this a glimmer of hope in solving my health and helping my family. I went from 29% body fat to 24% in 6 weeks. Insane lost 12lbs. Thankfully my husband found another job, and I turned around and did this for myself. To see how far I can push. I sure did! I cried pretty often in the middle of workouts, staying in good health truly protected my mental health during this time. As a mom of 4, I would highly recommend this app, based on the ability to work out from home and the gym. The community gave me accountability, the push to keep showing up. Thank you.

I love this app and the workout program so far. It’s easy to follow the workouts, watch a quick demo on the moves, and track your weight and reps, all in the same app. I feel more productive in the gym not that I have a plan instead of just doing whatever I felt like at the moment. I’m one week in and I’m so sore all over in places I haven’t felt sore before.

I did this to hold myself accountable, what I didn’t know is I would have the worst 2 weeks of my life. Some very personal things have put me into a dark place. But I’ve been able to focus on this challenge and stay engaged with some of the most amazing people! Thank you Erin ❤️❤️❤️❤️

This program is absolutely fabulous. I love that both gym and at home workouts are equally challenging. I found it to be the perfect length of time and very rewarding when crossing off each workout. The app makes it super easy to log your progress, which I love being able to do that. I loved my results and can’t wait to try more of Erin’s programs!

I’ve worked several eight week programs and this was my first six week. I loved the length and found it optimal. I really liked how you mixed up programming’s half way through….it was refreshing and kept engagement. I really liked the sprints you included as it made me feel youthful again. Overall, fantastic program.

I absolutely loved the variation this challenge provided— switching it up part way through. That helped me stay focused and I think optimized my results!! The community is by far the most motivating part of the challenge— if I’m feeling flat, I check in on others’ posts to feel encouraged and excited to keep going!
