Change the plan without hunting through settings
Tell Coach the result you want or the constraint that changed. It can read the relevant programme context and ask RACK’s existing training systems to build a new overall proposal.
Build the lifting programme around a tested max, estimated max or reps-at-weight target.
Keep, rebuild or add a 5K-to-marathon run plan while the lifting side changes.
Rebuild around the days you can train, a fixed week or a flexible rolling schedule.
Tell Coach what equipment is available and let the programme system find a compatible route.
An AI fitness coach that works through the app
Coach is not a second programming system sitting beside RACK. It is a conversational way to use the programme, schedule and training-history capabilities already inside the app. The training systems handle the structure; Coach helps you steer them.
Keep the reason attached to the change
A proposal carries the goal and constraints that produced it. That makes a 100 kg bench target, a three-day training week or a limited-equipment plan part of the programme itself instead of advice that disappears up the chat.
