For optimal results, making a mind-muscle connection is key. Mind-muscle connection is a term used to describe the focus on the muscle being used and consciously placing intention behind the movement. In order to have proper control over your body, you must create and maintain neurological pathways. This takes time and focus, but will soon become habit. Without making a conscious connection to the muscles you are working, there is more reliance on momentum, putting stress on your tendons and ligaments. If you find it challenging to make a connection to a muscle while doing weighted exercises, try lowering the weight, slowing down the movement and avoiding any swinging or bouncing.
