Developing the mental edge:
When you are training, use positive mental images throughout your workout to create feelings of speed, strength, and power especially during your set up before each repetition.
If you’re squatting, visualize your body wrapped in a cocoon of tightness. Inflating the lungs, pushing out with your abdominal wall, squeezing your glutes as tightly as possible.
If you’re snatching, see the lift in its entirety as fluid poetry in motion. Gripping the bar tightly, setting your hips and shoulders, inflating the lungs, pushing out with your abdominal wall, moving your body around the barbell as you apply force to it, bracing for impact as you catch it overhead.
See yourself completing each repetition effortlessly. Focus on your movement.
Use visualization before, during and after your training to build confidence and new motivation.
