When i'm doing standing calf raises, at the top of the movement, i'm finding it really difficult to squeeze my calf muscles and develop the mind muscle connection with the muscle. I'm not sure why this is the case, because when i used to train calves consistently about a year ago, i could always squeeze the calf muscles for every rep at the top of the movement. Any tips would be much appreciated. For instance, for some reps, I feel it more in the ankle than the calf muscle itself.
