Kick-Off/Push-Off

If you are able to stand on the floor of the pool, with your back almost leaning against the wall,

• place one leg, knee bended, with foot flat on the surface of the wall (leg position should look something like and 'L' shape underwater)
• start kicking softly off the wall with the bended leg and slowly raising the other leg from the floor to the wall
• as soon as the other leg touches the wall, kick-off the wall with both legs together
• position hands straight like an arrow head - see photo below (this position allows you to glide further)

• do the flutter kick or start swimming when the glide starts to fade out...

If your feet is unable to touch the floor of the pool,

• hold on to the wall with one hand and body twisted a little to the front (almost 45 degrees), *sigh* wish I had some pictures to show what I mean...
• place leg position as of the above steps ('L' shape)
• stretch the other hand straight in front, getting ready to kick-off
• start kicking off the wall with both legs, slowly releasing hand from wall and moving it forward in line with the other hand
