The problem really happens when you assume that what is helpful yesterday is the same thing that is helpful today. And they both can be different from what’s helpful tomorrow. ​ Are you working out too much, because that’s just what you do? Most athletes have gotten to the point of needing to step back and admit that whoa, I shouldn’t actually run this week because my knee is pretty fucked up right now, and I kind of wish I took it a little easier last time. Maybe then I wouldn’t have gotten to where I am now.
