Why do ProLon® with MobiGym instead of simply doing it on your own?
The ProLon kit gives you the structured 5-day nutrition program.
MobiGym adds the measurement, guidance and accountability around it.
Your September Challenge includes:
• Preparation before starting
• Private WhatsApp support
• Daily guidance and check-ins
• Body Composition Analysis before the challenge
• Body Composition Analysis after the challenge
• Personalized interpretation of your results
The two assessments normally represent €76 in value.
Most importantly, they allow us to compare your individual response before and after the five days.
Before Measurement → 5-Day Challenge → After Measurement
That reflects the broader MobiGym philosophy:
Measure → Act → Re-measure.
📅 Official registration closes 12 September
🚩 Challenge starts 19 September
5 Days. Measure the Difference.
