Occasionally you stumble across a Youtube video that really speaks to you. Recently I found this one. It is only 15 seconds long. What it says is— Watch!! THIS is how to do it.
Marco Foyot shows the same thing in this coaching session; his first boule (at around the 15 second mark) is a beauty.
When lobbing, do NOT come up off your heels and onto your toes like the student is unconsciously doing at the beginning of the video. He thinks he’s imitating Marco’s form, but he’s not. (This is where a coach can help.) Marco’s feet stay flat and firmly planted on the ground at all times; his heels never leave the ground. Your feet are your base; you want a solid foundation for your throw. You throw with your arm, not with your toes.
