I want to strengthen my joints and back and I want a professional to help me and I don’t want essential oils to be part of it

Yoga works; weightlifting does too and it’s quicker. You don’t need to lift as heavy as I do (relative to your size/gender) to strengthen your joints. Something more moderate with higher reps is good. Yoga does indeed work, but weightlifting gets you there faster and makes your joints and your back stronger than yoga alone can.
As long as you use proper form not only do your joints get stronger but the muscles around them help insulate them and protect the joints from harm. It’s a myth that weightlifting does damage to your joints. Sure, if you deadlift some absurd amount with bad form over many months or years, you will hurt yourself. But that’s true of any exercise, even yoga.
So the slow way is yoga. The quicker way is lifting weights.
