I have been training with Jentzen for around three months. I play club volleyball and wanted to increase my vertical jump and lateral speed. In the first 2 weeks of training I increased my vertical by 2 inches and it has since increased at an average rate of 2 inches every two weeks. My vertical started at 11 inches and is now 21 inches. As for lateral speed, I am getting to my blocking pins easier and faster allowing me to get more blocks. This is one of the best decisions I have made to increase my volleyball skills and make me an overall better player. Jentzen makes it fun and enjoyable to train, and he is very encouraging and motivating.
