T. E. M. P. O. does not mean “slow it down, Susan!” Often a FASTER tempo creates a faster club head speed. (Henrik Stenson and Michelle Wie to name a few fast tempo swingers)
Good tempo is a product of FEELING the club head and staying with the motion.
The “Sergio” helps you feel the weight of the club and stay in sync with the motion
The “One Armed Man” makes the club feel heavy so you have to rely on smoothness and momentum to swing the club.
The “Machine Gun” helps you feel the connection between your upper and lower body motion
