Mind/Body Connection-When lifting weights focus on the muscle(s) that is doing the work! 

The Cleveland Clinic Foundation in Ohio conducted case studies that included visualization sessions that recorded brain activity while participants imagined exercising a muscle.  They reported that muscle strength can be maintained and that there are strength benefits by just THINKING about exercise.  Having the mind/body connection will bring your weight training sessions to the next level!
