That's a nice Ski picture, anon.
A lot of people have written about how different lifters have different needs in terms of variety. Westside has its congugate method, which itself was based on some Russian research iirc. But basically if you're getting burned out on an exercise, switching variables can get you revitalized.
Adding bands, belts/beltless, closer/wider grip, closer/wider stance, squatting high/low bar, pulling sumo/conventional, adding in accessory exercises for parent exercises.
So if you're getting burned out try these.
