Marie Steffen x Julia Reppel Mobility eight day challenge review
The last month and the beginning days of October have been pretty rough for me, my sleep schedule has been terrible and my diet has been pretty irregular. As for my workout routine, I successfully trained a 5K and tried to keep up with Sydney Cummings' BOLD program but I felt very tired. I decided to just focus on mobility, an aspect of fitness I've always neglected, in hopes of deloading my body to feel better.

To be completely honest: I hate stretching. I'm extremely stiff and I tend to skip the stretches after my workouts, my mobility overall is okay but could be so much better. Determined to overcome my fear of stretching, I searched Julia Reppel's channel for beginner challenges and found a short challenge made in collaboration with Marie Steffen. Julia, a sport scientist and Marie, a personal trainer and former bodybuilder, are both from Germany and post follow along workout on their respective channels. Julia's channel is mostly focused on mobility and Marie's channel hosts Pilates, mobility and strength training workouts; both channels are pretty active and getting constant new videos. I found out about Julia's channel while searching cool down for runners, her concise videos and great credentials caught my eye and made me try more.
As for Marie, I tried a few of her Pilates videos before but they were too advanced for my level and had no vocal cues. Though I did enjoy her polished editing and graceful movements, her workouts are definitely too overcomplicated for those unfamiliar with Pilates. Now that I was more familiar with Pilates and in urgent need of deloading, I decided to give their collaboration a try.
The challenge can be found in both channels, I followed the playlist from Marie's channel. These videos were not created as a program, but I decided to follow them as such.
Challenge details:
- Eight videos total, I did one every day.
- I'd definitely label these videos as intermediate.
- Videos range from 15 to 25 minutes in length.
- No equipment required besides a non slip fitness mat.
- Warm up and cool down are provided in every video.
- No vocal cues are provided, some written cues are shown on screen.
- Easier and harder modifications are provided for many exercises. All exercises are low impact.
Day 1 is a great start to the challenge. With circuits targeting the spine, hips and shoulders respectively, this workout is excellent to train your mobility with simple exercises. The transitions are easy to follow, easier modifications are shown by Julia if you're not too confident on your form. This session felt so doable and made my entire body feel less tight, so I decided to keep up with the challenge. This video is also fairly beginner friendly, so don't hesitate to try it even if you're a beginner to mobility.
Day 2: Pilates x Mobility
Day 3: Full Body Mobility Animal x Primal
Day 4: Daily Morning Mobility Routine
Day 5: Deep & Dynamic Stretch + Mobility
I wouldn't recommend this workout if you're not familiar with Pilates, Yoga or other mat based bodyweight practices. Yes, the workout challenges your core but your wrists and shoulders will be challenged with many bird dog and side plank variations. I didn't quite enjoy this workout as much as the others on the playlist, the repetitive moves didn't flow as well. This one has no modifications and seeing Julia struggle with some of the moves was refreshing.
After finishing the playlist on Marie's channel, I noticed that Julia had her own playlist with one more video. This Pilates based workout is beginner friendly, combining mobility moves with the Pilates methodology of controlled exercises. This flow was great and overall far more dynamic than the Day 6 Pilates x Core workout, so I recommend substituting for this one if you're more of a beginner. As in other videos, Julia show easier modifications of the harder movements.
- Both trainers have excellent form.
- Modifications are provided for harder exercises.
- Creative moves and flows.
- All low impact.
- Warm up and cool down are included in every video.
- Comprehensive approach to fitness including Pilates, mobility and functional training.
- Movements are previewed on screen.
- Excellent video quality and editing.
- Great background music choices.
- No vocal cues. Written cues and previews are provided but transition times are very fast.
- Most videos are not beginner friendly even if labeled as such.
- Some exercises can be hard to follow.
- Can be heavy on the wrists and shoulders at times.
