Works on fundamental blocking technique
Leg strength to block and recover without use of hands
Driving knees forward towards the ball cutting down the distance
Head and chin is up
Glove out in front or not in contact with ground
Elbows not beside ribs
Body comes up before going down to block
Catcher moves down quickly, glove is buried deep in stance
Elbows and arms creating a little more width
Recovers quickly without assistance from hands
Stays athletic throughout the process
