So,
@kaemicha donāt do squats, donāt do deep squats, donāt do whatever a split squat is, donāt practice getting up and down off the floor and the old adage āuse it or lose itā applies only if you have not already lost it, or are about to lose it, or you are in chronic pain.
The only way moving lubricates your joints is, oh wait, moving does not lubricate your joints because you are not a car, a bike, or a tread mill. Moving, specifically walking, can help maintain your joints and ease stiffness, but lubricate-nope.
@kaemicha talk to your doctor about what you can and can not do. Seek help from the senior services in your town. listen to some of the advice given here, but always check with your doctor first on what level of movement you can do. Most people who have the ability to walk, can walk at least a little.
Be careful.
