Ok, in my life,I have been thaught 2 ways to do a sidekick.

Some say the supporting leg should be bent for more stability and other things...

Some say the supporting leg should be strait for more power...

Both seem to work well and give stability and strenght, I have been doing it the leg bent for one year then, I was told it had to be leg strait and did it for a year like that , and recently I have been told I should do it leg bent.

anyone knows whats the real way of doing it, or it doesnt really matter?
