Lol, thanks Aesir . Just set short term goals for every week or every workout. Personally, my goals consist of either getting a rep or two more on each set or increasing each set by 5 lbs. The weight adds up faster than you would think. Key: The higher the intensity, the better the results. Many times I up the weight with doubt in my mind that I could complete the set. Usually, your body is able to do more than you believe it can.
It's not because I can, but because you couldn't if you tried.
