Haven’t changed my exercises for years.
I would say to just add more variety, tempo, intensity, reps, sets, daily/weekly volume, static holds, switch to unilateral.
It’s like eating a ribeye. You don’t change to sirloin and swear it’s better. You try a different salt, cook it over a grill/pan/fire, French butter, aged, etc chew it slow, try it with chutney, sweet potatoes…
Maybe not the best analogy… Just hungry atm
