Side planks are dumb. they obviously don't understand the knee. the knee is a hinge joint and you putting the stress at 90 degrees directly accross the hinge! duh. No human being would ever perform this motion for any reason at all, consequently the MCL and LCL are not that strong. they wouldn't have to be because we would never do this. And you're supposed to be an expert?
