I restarted playing golf a month ago. 9 holes at first to get the muscles active. Dreading the next 18 hole round. The walking is ok as I am out every day anyway but it is the muscles used during swinging the club that ache. Lack of use. Same with gardening. Little used muscle groups suddenly crying out in pain.
I’ve had inflammation of the Achilles tendon in one leg that comes and goes. That knee aches a bit too.
I need to up my mobility exercising/ stretching.
