Don't quit because you can't do a 100 pounds once. Do ONE pound a hundred times until you CAN do it.
I am often caught in this thought when it comes to different exercises, especially Pull ups or Chin ups.
No other exercise is as a great example of Bifurcation tasks.
Either you CAN do a Pull or Chin or you Can't. Either you do or you die. NOW, you have two choices if you can't. You can either lose weight (hmmm, I train so I can eat, and I eat so I can train) or you can get stronger. I like option 2.
If you can't do 10 reps, why not do 1 rep over 10 sets? Same volume! Just different intensities.
Anyway...I wrote about this a while ago, but it's been on my mind the last couple days. All I am certain of, it works!
