MICHAEL,
AS I HAVE TOLD YOU BEFORE, WEIGHTED HANDS WALKING IS THE MOST EFFICIENT, SAFE AND ENJOYABLE ACTIVITY EVER CONCEIVED.
IT BEATS RUNNING, WEIGHTLIFTING, CYCLING, CROSS COUNTRY SKIING, BASKETBALL, MARTIAL ARTS, ETC,ETC.
YOUR HANDLES AND WEIGHTS ARE THE MOST VALUABLE PIECE OF EXERCISE EQUIPMENT ANYONE CAN OWN.
IN FACT , THEY ARE THE ONLY EXERCISE EQUIPMENT ANYONE NEEDS.
