The ranking
- NexLife — 1:1 fitness coaching included. Resistance training protocols built into Care360. Protein 1.6–2.0 g/kg target. Critical sarcopenia mitigation for athletes.
- Mochi Health — coaching-centerpiece model with athletic populations in mind.
- Found — app-driven; works well for self-directed athletes who track macros.
What matters for athletes on GLP-1
- Protein: 1.6–2.0 g/kg body weight (higher than for sedentary populations)
- Resistance training: 2–3 sessions/week minimum; compound lifts; progressive overload
- Conditioning intensity: Don't slash conditioning during dose escalation — symptoms usually resolve in 1–2 weeks
- Hydration: Endurance work + reduced thirst sensation on GLP-1 = aggressive hydration plan needed
- Performance monitoring: Track lifts, conditioning metrics; if performance drops >15%, dose review
