Preserving Muscle Mass After 50

A practical training and protein protocol — prioritizing real food, with realistic alternatives (bars, whey) for everyday life — based on international scientific literature. Designed especially for people who lost weight with weight-loss medications and need to rebuild lean mass.

Why this matters

Losing weight with medication also costs muscle mass

Body composition studies with semaglutide and tirzepatide show that part of the weight lost is lean mass, not just fat. Without a protein and resistance-training strategy, that loss affects strength, metabolism, and functionality — especially after 50, when age-related sarcopenia is already accelerating on its own.
