Phase 1 — Foundation
Build movement quality and baseline strength. Every rep should be controlled. If you can't do a full push-up, do it from your knees — but track when you move to full. Frequency: 4 days on, 3 off.
Phase 1 priority: don't train to failure. Stop 1–2 reps before you can't continue. Your joints and tendons need time to adapt even when your muscles feel ready for more.
