What going in your mind in between sets can make the difference between awesome gains and No gains

Mind is the builder.. Whats going on in YOUR mind as your resting for the next set? What are you saying to yourself? What kind of mental pictures are you making? Read: are you mentally rehearsing yourself blazing through the set to come? Are you breathing deeply and exhaling powerfully so that you muscles are getting all the oxygen they need to work? (Note: exercise like the squat AUTOMATICALLY cause you to breath deeper... and thus automatically help you burn more fat easier and faster... cool right?) Are you paying attention to how your muscles FEEL vs. looking in the mirror or kissing your bicep because it pumped from the recent set? Are you keeping in mind your fitness goals? The reason I ask you is because when you keep your fitness goals in the front of your mind as you train, you'll have a constant remainder of where you want to be. The mind can be like a wild horse... like a untamed beast.... sometimes you need mental devices to .... keep focused on the outcome. Are you talking to yourself and visualizing the end result of your training session ie you're feeling stronger than when you started? If you're not doing any of these things, or anything similar, then... You're farting in the wind. Amir
