About AgeShift
Training that fits your life, not the other way around
AgeShift was built for active people in their 30s, 40s, and 50s who are juggling careers, families, travel, and real life but still want to train seriously.
Most training apps are built around perfect weeks and single goals. They assume you have unlimited time, no stress, no injuries, and no competing demands. That is not how real life works.
AgeShift is different. It is a system that reasons about your whole life: sleep, schedule, recovery, and sport mix. It builds a training plan around all of it, automatically.
Founder
Heinrich Tessendorf — Founder, Age Shift App
Heinrich built Age Shift App after years of coaching active adults and seeing the same problem: people quit not because they lacked motivation, but because their plans couldn't keep up with their lives.
