A yoga coach would help you with:

1. Proper alignment
Learning how to place your feet, hips, spine, shoulders, and neck correctly.

2. Safe modifications
A good coach can adjust poses for tight hips, back stiffness, balance concerns, shoulder limits, or recovery needs.

3. Breathing
They can teach you how to connect movement with breath, which is where yoga becomes calming, not just physical.

4. A personal routine
Instead of guessing, you could get a simple routine for strength, flexibility, balance, posture, and stress reduction.

5. Accountability
A coach helps you get started and stay consistent.

I would look for a coach who teaches beginner, gentle, therapeutic, restorative, or mobility-based yoga — not someone pushing advanced poses, hot yoga, or intense power yoga right away.

A good first goal would be:

Hire a yoga coach for 4 sessions, then practice on your own 3 days per week for 15–20 minutes.

Ask the coach:
“Can you build me a safe beginner yoga routine focused on strength, flexibility, balance, breathing, and calm?”
