And like all lies...they don't stay hidden.

Sure, nobody saw that terrible squat form yesterday, and I wasn't there to laugh at the ridiculous pushups with a sagging back.  No one can confirm that you only took 175 paces during the Farmer's Carry when you were supposed to do 200, but it's all good.  In the end, the iron...the work...it doesn't lie; it's just you.  

Your fitness (mental, spiritual, and physical) is a debit account.  You can only withdraw what you've invested and when it comes time for a trial or a test, that's when your half-assed performance will catch up with you. 

When I worked as a personal trainer in a local gym, I would be amazed at clients who would come up with all kinds of excuses for why the weight wasn't coming off.  They would swear that they were sticking to the plan and giving it their all in the gym and, more importantly, in the kitchen.  The fact of the matter is...many of those folks just weren't committed.  They wanted the easy way out...and you know what, I'm cool with that, just don't lie about it.  

Invest sweets and fried foods regularly...that's what you've got to withdraw from in your time of testing.  Invest sub-par effort in training...that's what you've got to rely on during your next physical trial.  Look ahead.  So much of this is just looking ahead at what's coming...and prepare for it.  

Whatever you choose, own it.  Don't lie to yourself about the quality of the work you're putting in...and certainly don't lie to anyone else about it.
