Professional table tennis player, 1st French League (PRO A), former player of Czech National Table Tennis Team, WR: 275.

I tested SpeedChain and Torso Burner during summer camp within the training for speed and swing speed. I trained with both products five days, after which there has been a noticeable increase in the flexibility of muscles, especially in the hips and abdomen. I felt improvement in overall coordination of rotational movements, especially in fluency during various phases of the swing. I recommend exercises with SpeedChain and Torso Burner, it is great and very effective way to increase the maximal speed of your shots.
