The problem with lifting or spinning the support foot when performing this kick is that one you are now connected to the floor with only the ball of your foot and two that the kick will be easier to block or redirect. Often the block itself will be enough to break your balance and cause you to fall. Another point is that the centre of gravity rises and leves you vulnerable and weaker with balance.

 

We tend to do it because it is easier to perform the kick. If we spin the support foot it places less strain on the achillies tendon which many people do not have great mobility in.

We lift the heel so that we can kick higher or in an attempt to increase kicking range.

 

How to correct this?

 

The first and most important part in correcting this error is that you need to be aware that you are doing it. Once you have recognised it you should;

work on keeping the front leg bent at the same level that it was when in your stance.

Picture a partner standing on your foot not allowing it to spin or lift.

Use the mirror to self correct this mistake.

Ask a training partner to stand on your foot in the attempt to keep it still.

Ask a training partner to practise blocking your kicks and focus on sending the power of the kick dirrectly at your opponent.

Avoid sending your centre of gravity too far past your supporting leg at this causes the heel to lift.
