Important Principles

1. No Pain

Strengthening should not cause joint pain. Modify or stop if painful.

2. Full Range (When Possible)

Use as much range as comfortable. Don't force through pain.

3. Alignment

Keep knee tracking over 2nd-3rd toe. Don't let knee cave in.

4. Progress Gradually

Add resistance slowly over weeks.

5. Don't Skip Hips

Hip strength is crucial for knee health.

1. Quad focus — Especially VMO

2. Hip strengthening — Controls the knee

3. Functional exercises — Squats, lunges, steps

4. Pain-free range — Don't push through pain

5. Consistency — Weeks of regular work
