I know that after 4-6 weeks of the same routine that its ability to work the muscles stagnates and you may hit a plateau, well I was wondering if there was a way to eliminate that problem forever, for me at least. Instead of changing routines every 4-6 weeks, what if I were to give myself a list of about 10 different exercises to do for each muscle group, and then when I work out, just choose a random 4-5 exercises. That way no workout is exactly the same, and it will keep it interesting for me. Does anyone see a problem with this? Would I not benefit as much from my workouts because I'm constantly changing it even if I keep up the same intensity? Any feedback appreciated. Thanks!
