CoachSync

hobodave/coachsync-mcp

Barbell programming tools wrapped in an MCP interface. This exposes warmup set calculations, plate loading math, and linear progression tracking from CoachSync, a coaching platform built around the squat, bench, press, and deadlift. You'd use this when Claude needs to calculate working sets from a percentage scheme, figure out what plates to load on the bar for a given weight, or track progression on a simple linear program. The source shows CoachSync itself handles workout calendars, form check videos, and coach-client messaging, but the MCP server appears focused on the strength-specific calculations rather than the full platform. Useful if you're building training logs, programming assistants, or anything that needs to speak barbell.
