7 Muscle Gaining Exercises

I am a big fan of mixing up workouts, so I would think of a muscle building routine as one of various types of workouts to seek out for the Tough Mudder.  Clearly a structured running program is critical and we should discuss everyone's approach to this on some other post.  

But if we're talking about resistance training, I'm also a fan of Cross Fit and muscle confusion exercises.  I've actually distanced myself from the type of routine in this video and haven't done a heavy weight routine in quite some time.  However, I do think that all of the exercises described herein are effective and I would maybe through in lunges of some sort as well.

A heavy resistance day is awesome for generating that power you want out of your movements and is complimented well with a strength training routine that focuses on explosiveness versus heft.

Anyway, just FYI.  Knowledge is power.
