Using the Speed System
Make sure the speed lines are not adjusted
too short, but that you can use the whole
accelerate range. To accelerate, first use
one foot and leave the other on the foot
board. When the first foot has reached the
footboard, and more speed is required, put
the other foot in the second speedloop
rung. Be careful not to push your heels into
the speedbag floor: this can strain and
damage the material.
