Should you switch up your workouts? This is something that found very situational, it really depends on what works for you. I personally do not switch up my workouts. I usually stick to a split Push, Pull, and Leg routine and I have been doing it weekly for 3+ Years now! I have been happy with the results of my workouts so I have never felt the need to change my workouts. Know your body and do what ever works best for you!
