 Your fist should go back to about two inches from your chest and when you punch out, punch out to about 95% extension. Do not extend your arms completely and do not lock out your elbows. Okay now I want you to do double time. One, two, three, four, five, six, seven, eight, nine, ten. Count as you go. Count them to ten. Every ten I want you to count. One, two, three, four, five, six, seven, eight, nine, ten.
