Stretching incorrectly = not stretching at all. Depending on your body type, sport or work, not everyone should stretch the same way or duration. Here’s my client who has a desk job performing the N° Stretch for Tennis players: We actively stretch Ilio-Psoas + back musculature Latissimus Dorsi + Serratus (rib region) to create + Fluid movements for Pain-Free Tennis or Golf practice.

Time-Money Efficiency + Return on Investment


In a society of over-consomption + over-information where things have to go too fast, where consumers have so many choices regarding service providers that actually all provide the same: PrivateFITNESSstudio – Bertrange has since 2011 proudly distinguished from concurrency with only and solely 30min of targeted Personal Training for a reasonable price: It has been 6 years now that clients have experienced science-proven results, kept it Long-Term and this business model not only is growing but also allowing to apply to a brand new Fitness Solution in the market of Fitness: PRIVATEFITNESSSTUDIO ONLINE COACHING where you count on the experience of a coach whose career has been built around busy yet ambitious people who don’t have time neither certainly money to waste on unprofessional -unprepared trainers who play in sub-optimal infrastructures that are far from delivering an individualised atmosphere that should characterise the ESSENCE OF PERSONAL TRAINING.


Personal Training has many factors that guarantee you success, but the 1° and foremost is the COMMITMENT aspect: show-up to your meeting with your trainer and make it happen NOW instead of later: MAKE IT HAPPEN NOW, NOT LATER, week after week, step-by-step for solid & healthier Long-Term Fitness success.

Once your technique improves, your ability to go from 1 exercise to the another with targeted rest (minimal rest) allows your heart rate frequency to be higher & see major qualitative improvements in your cardio-vascular system in a natural & adapted way to your physical level.

Muscle mass isn’t necessarily a main body-building concern: POSTURE is greatly enhanced by adding muscle mass where it matters the most.

Abdominals are the most wanted muscle in the body, yet the least qualitatively trained area by fitness professionals around. In PRIVATEFITNESSSTUDIO you experiment the safest yet most effective abdominal exercises you could ever try to improve the way you look & feel once for all.

Exercises we select get your life easier: carrying a Maxicosi with your baby inside, carrying shopping bags, transporting heavy objects or simply carrying anything  asymmetrically day to day causes back pain, the only way to prevent it is using proper Functional Training that adapts to your  own individual needs, respecting your past injury profile.
